THE CEO'S REASONS
24 In order to place Greenpeace's contentions in context, it will next be necessary to explain the CEO's process of reasoning.
25 In describing the process of assessment of the application, the CEO said that he had referred it to the ARPANSA Regulatory Branch for its review in detail, which Branch:-
"…is made up of officers with a wide range of expertise in radiation protection and nuclear safety, the officers leading the review being of international standing and highly experienced in assessing the safety of ANSTO's nuclear facilities. … An international expert was engaged to advise the staff and assist in the assessment of seismic design. The Canadian Nuclear Safety Commission provided an expert to work on thermal-hydraulic and transient analysis. …[T]he Argentine Nuclear Regulatory Authority (ARN) undertook a review of the PSAR [Preliminary Safety Analysis Report] against its regulatory standards and the leader of the ARN Review team … advise[d]…."
26 In considering the matters to be taken into account under s 32, the CEO, noting that the Act does not define the phrase "international best practice in radiation protection and nuclear safety", stated that he had "tried to find the plain meaning of the term, having regard to the context of the Act as a whole and especially the object of the Act". The term "best practice", to his knowledge, is not one used in the nuclear industry internationally as a particular term of art. However, in a foreward to a recent publication by the International Nuclear Safety Advisory Group ("INSAG") - Basic Safety Principles for Nuclear Power Plants INSAG (1999) - the Director-General of the International Atomic Energy Agency referred to the publication as presenting the "principles underlying the best current safety policies and practices of the nuclear power industry". The CEO explained that he had dealt with the notion of "international best practice in radiation protection and nuclear safety" from "first principles", bearing in mind that he was dealing with the proposed construction of a research reactor.
27 The CEO explained that the process involving designing, constructing, and then operating, a research reactor has several aspects:-
28 First, there are the "higher-level" decisions about the approach to be taken in the design to radiation protection and nuclear safety, and about how those approaches are to be "analysed and reviewed". The CEO refers to Annex 2, a summary of a "very well-established international safety framework" for these activities set up through the International Atomic Energy Agency ("IAEA") and associated bodies and through International Conventions. (Annex 2 is annexed also to these reasons for judgment for ease of reference.) This safety framework "strives" to be a description of how things "should" be done, rather than "merely a summary of how they are done". The CEO said:
"I accept that they represent international best practice [("IBP")] for the conceptual and analytical aspects of a design and construction project. Certainly, there are no competing approaches in respect of design and construction of research reactors even claiming to be [IBP] in radiation protection and nuclear safety."
29 Secondly, a specific reactor design will include a number of safety features - systems to detect problems and to shutdown the reactor, to cool the core after shutdown in various circumstances and to contain and control any released radioactivity. There is "increasing international agreement" about the desirable approach to such safety features - both within the general safety framework in Annex 2 and in discussions of future reactor systems. It is also a matter that can be addressed by comparing proposed safety features with those built into recently designed and constructed reactors in other countries.
30 Thirdly, in the construction phase itself, there are issues about management of construction, quality assurance approaches, and the codes of practice and standards for the construction of items important to safety. The CEO said: "[a]t this more detailed level, the international safety framework can only point to [IBP] in the broad sense". The codes of practice and standards should be consistent and chosen from those used internationally, "though there may not be a single set of such codes and standards that alone constitute [IBP]". IBP in radiation protection and nuclear safety may capture "more than one way" of doing things at this detailed level.
31 Fourthly, there are the radiation protection and nuclear safety outcomes that are actually achieved. These "can only be estimated" from the design at this time, yet it would nonetheless be "appropriate to benchmark these outcomes against those achieved in recent, modern research reactors in other countries, where these are available."
32 The CEO then expressed the view that "taking into account" IBP relating to radiation protection and nuclear safety "involves the following being considered":
· The radiation protection and nuclear safety objectives included as a part of the design, compared with those laid out in the international safety framework that is found to be IBP.
· The specific safety features of the design compared with those recommended in the international safety framework and most successfully applied in recent research reactor designs.
· The management of the design and construction project, the codes and standards applied to the design and construction of systems important to safety, compared with management approaches and the codes and standards used for similar systems in reactors designed in other countries with best practice safety systems.
· the design outcomes for occupational radiation doses, discharges to the environment and consequent radiation doses to the public, and the likelihood of core damage, compared with those achieved in recent research reactors in advanced countries.
33 The CEO said that he had also considered the issue of defining "[IBP] in radiation protection and nuclear safety" with regard to the protection of the environment from the harmful effects of radiation. He said:
"I have construed my role, derived from the object of the Act, as being in relation to the protection of environment from the harmful effects of radiation. Other harms to the environment that may arise from the construction and operation of the [Reactor] were assessed in the EIS [Environmental Impact Statement] process."
34 The CEO noted that "[IBP] in relation to radiation protection and nuclear safety and protection of the environment" is changing. Although the International Commission on Radiological Protection ("ICRP") took the view that measures to protect humans from radiation also protected the environment, this view is currently coming under challenge. The CEO said:
"I consider that there is not yet an established radiation protection system for non-human species that can be regarded as [IBP] and for application in the context of a research reactor, other than focussing on the protection of humans."
35 Noting that the application was for a licence to construct the Reactor, the CEO adopted "the plain meaning" of the words "construct a controlled facility" in s 30(1)(b) to be:-
"[The] manufacturing, assembling and installing structures, systems and components of the reactor; carrying out civil works commencing with bulk excavation for foundations; and performing tests, inspections and commissioning of any of these items, up to but not including the loading of nuclear fuel."
36 Observing that s 30 of the Act "divides the conducts" relating to a "controlled facility" into these: prepare a site; construct; have possession or control; operate; and de-commission, dispose of or abandon; the CEO stated:
"Several of the matters to be taken into account by the CEO in making a decision about a facility licence refer to the conduct proposed to be covered by the licence. Taken literally, this might mean that, for example, in relation to the matter of undue risk, I need only consider the risks posed by the construction of the reactor, not by its operation, as that would be covered by another licence application. I do not interpret the Act and Regulations in this manner. To do so would empty the assessment of undue risk of meaning, as there are very few, if any, radiological risks involved in the construction phase, per se. My view is that Parliament divided the life of a nuclear installation or other controlled facility into the phases described above to reflect the complexity of such major projects and to ensure that they are properly assessed at each stage as they are developed."
37 The CEO went on to say:
"In assessing whether to issue a licence to allow the preparation of a site for the [Reactor] at Lucas Heights, I did make an assessment as to its operation on that site, as best as could be judged at that conceptual stage of the design. Similarly, I have taken into account any operation of the [Reactor] in my assessment as to whether ANSTO should be issued a licence to construct it, in the light of the greater amount of information now available from the design of the reactor. Satisfaction at this stage would not prevent me refusing a licence to operate if it were that significant siting or construction issues arose in the intervening period. That is, should the project proceed to seeking a licence to operate, then the safety will again be assessed, this time with the 'as built' reactor to review. This would seem to me to be Parliament's intention and consistent with the object of the Act. I consider that it also meets [IBP] in nuclear safety - for example, the IAEA safety guide on safety assessment of research reactors states that:
'To obtain a construction licence or an agreement for the start of construction, the operating organization shall submit information which demonstrates that the design will result in a safe facility and that construction will achieve the design intent.' "
38 In considering "Design for Radiation Protection", the CEO considered several waste management issues, noting that the Preliminary Safety Analysis Report ("PSAR") described the proposed waste management system for the Reactor, and the proposed arrangements for monitoring, control, segregation and classification of wastes. The CEO stated that the ARPANSA staff was satisfied with the on-site management of wastes proposed, noting the continuing progress with the ANSTO waste management action plan and the special licence conditions imposed on the existing waste operations licence, and that the CEO accepted this assessment.
39 The CEO also noted that ANSTO's application is predicated on low level wastes finally being sent for disposal to the national low level waste ("LLW") repository; and that ANSTO was designing a facility on the site to condition waste for transfer to this facility, which is being planned by the Federal Government as a national facility for use by all jurisdictions and will represent the route for final disposal of the LLW by ANSTO.
40 The CEO dealt separately (in Part 7) with the management of spent fuel and the resulting waste form after it is reprocessed or conditioned. Other radioactive waste management issues were, as has been noted, dealt with earlier (Part 4) in the Reasons.
41 The CEO stated:
"This issue is different from the other assessments I have undertaken. ANSTO can be held to be accountable and to be assessed in its proposals for management of spent fuel and radioactive waste until it is sent for disposal or long-term storage at national facilities. The development of these facilities is the responsibility of another agency and subject to Government policy."
42 In considering options for the management of "spent fuel" (fuel that has been used in a reactor for the period of time for which it was designed), the CEO noted that the key features of ANSTO's spent fuel management strategy are captured by a diagram showing three possible routes, as follows:
1. Reprocessing by COGEMA in France;
2. INVAP (an Argentine company, the contractor for the design and construction of the Reactor) to arrange processing in Argentina; or
3. INVAP to provide an alternative solution (presumably involving processing in another country).
43 After explaining the meaning of "spent fuel", the CEO stated:
"Spent fuel is highly radioactive as a result of the presence of fission products. It must be treated very carefully to ensure the safety of the operators who deal with it and to ensure that there is no release to the environment."
44 The CEO observed:
"Not all countries that operate nuclear power plants have decided that they should reprocess their spent fuel. The reasons for not proceeding with reprocessing are broadly two fold: one is that the economics of the reprocessing may not be regarded as favourable, given the ready availability of uranium on the world market; the second is that reprocessing does result in the separation, particularly, of plutonium and gives rise to concerns about nuclear proliferation. So, for example, the United States has a policy of not seeking to reprocess fuel from its nuclear power plants; Germany has decided that it will not continue reprocessing after 2005; and other countries such as Canada and Sweden have decided they will not use reprocessing. Yet other countries have not made a decision either way at this stage."
45 The CEO went on to say:
"… in the case of the [Reactor], the issue of reprocessing is not one that is contemplated primarily on the basis of seeking to recover materials for further nuclear fuel…. Rather, what ANSTO is seeking, I believe, is a way of conditioning the spent fuel such that it is in a form whereby it can be stored and ultimately disposed of. The reprocessing process adopted by COGEMA La Hague produces a satisfactory vitrified waste form. The general waste form produced by La Hague is known to me and I regard it as likely to be able to be safely stored for a significant period of time in Australia. There has not been a full assessment of this carried out by ARPANSA nor has ARPANSA made any assessment of the suitability of the COGEMA vitrified waste product for final disposal in a geological repository."
46 The CEO then stated:
"For the [Reactor], an alternative approach to the reprocessing of spent [Reactor] fuel is a form of conditioning. … It may also be possible for conditioning to be a physical process and for the spent fuel to be included in physical containment for direct disposal.…"
47 After explaining the estimated volume of vitrified fuel waste and associated compacted waste after 40 years of operation of the Reactor, the CEO stated:
"I do not foresee any major technical obstacle to the storage of this volume of material and quantity of radioactivity in a secure manner for a long period."
48 The CEO observed that it had been vigorously argued in very many of the public submissions that the construction of the Reactor should not be permitted on the grounds that the arrangements proposed by ANSTO for the management of spent fuel would not be effective. The option of reprocessing by COGEMA in France was objected to on the footing that:- (i) the type of fuel proposed for the Reactor is said not to be suitable for reprocessing in the La Hague plant; (ii) there is a legal challenge on foot in France to the processing of Australian spent fuel in La Hague; (iii) the existence of the La Hague plant and other similar facilities in Europe is becoming a matter of political and environmental controversy, with pressure to close down such plants. In respect of the other options, including INVAP's arranging processing in Argentina or another country, it was objected that such strategies require international transport of spent fuel and radioactive waste and that this is unsafe.
49 The CEO was aware that the particular process adopted at La Hague is not suitable for dealing with uranium silicide fuels in bulk (as will be generated here). However, referring to a letter sent from COGEMA to ANSTO in September 2000, the CEO said:
"I judge that it is reasonable to expect that …[a technical]… changeover will occur in a time period that will allow reprocessing to occur via COGEMA, or at worst for there to be a small quantity of U Si fuel remaining requiring a different approach."
50 In relation to the possibility of reprocessing Australian spent fuel in France, the CEO found -
"…there are paths available for the authorisation for reprocessing of the Australian fuel, including the [Reactor] fuel, but a political decision [in France] may be required. In the application, ANSTO refers to an agreement at inter-Governmental level to support the contractual arrangements."
51 Observing that opposition to Sellafield (UK) and La Hague turns largely on the OSPAR Commission (being an agreement of north-east Atlantic countries regarding reduction in discharge of pollutants in those waters), the CEO concluded:
"[T]here is no doubt that the other decisions made by the OSPAR Commission, albeit not supported by the UK and France, shows that there are substantial political pressures in Europe to end reprocessing and it might well be that these succeed sometime during the life of the [Reactor]."
52 As to reprocessing in Argentina or a third country, the CEO said:
"I do not find that this fall back option is less developed than that offered by the COGEMA option. I expect ANSTO and INVAP, as part of any application to operate the reactor, to develop the proposals further.
The final option of arranging for processing in another country has not been addressed in any serious way at this time and I have not relied upon it in my assessment."
53 With respect to international transportation, the CEO considered that, while the international system "is not beyond criticism", international transport of Reactor spent fuel and resulting wastes "could be conducted safely". The Greenpeace report makes "a valid point" about Australia's emergency planning, and the CEO was aware that this is being addressed.
54 The CEO noted that the Australian government proposes to build a store for intermediate level radioactive waste; that an advisory group has been established and is preparing advice on the criteria for such a store; and that the group, which includes an ARPANSA officer, has produced a discussion paper that has been released for public comment. The proposal is for a store designed for safe storage "for a period of up to at least fifty years until a suitable geological repository is established". In the CEO's view, it would be "foolish" to design a store for a life of only fifty years. The issue of final repository may take a considerable amount of time. The CEO considered that there is no difficulty with safe storage well beyond 100 years.
55 The CEO stated:
"I earlier offered the opinion that at the time of the construction licence, I would expect to see progress in moving to establish a store and the above is progress."
56 The CEO went on to identify the following as issues raised in the public submissions in relation to "spent fuel and waste management".
· Whether ANSTO has demonstrated that molybdenum fuel will soon be available, or that silicide spent fuel will be able to be managed.
· Whether there should be an option for the handling of spent fuel entirely within Australia.
· The degree of progress with the national waste repository and national waste store before construction and operating licences may be granted.
· Adequacy of any strategies to monitor and control radioactive discharges to ensure that radiation doses to the public would be as low as reasonably achievable, social and economic factors being taken into account.
57 The CEO said that he had "taken all these issues into account and discussed them where appropriate [in the Reasons]".
58 The CEO noted that the issue of spent fuel and radioactive waste management, which had been discussed at Part 7 of the Reasons, was also considered in the Report of the Nuclear Safety Committee, in addressing the implications of uranium silicide fuel and the changeover to uranium molybdenum fuel. The CEO stated:
"The working group suggests that it appears that the earliest that U-Mo fuel will be qualified internationally for use will be 2005, and that there will be a further period of consideration by ARPANSA before approval could be given for the loading of the new fuel. The working group points out that this may have implications for the amount of spent U-Si fuel that will be generated by the [Reactor], and therefore the capacity of COGEMA to reprocess the fuel and return the waste to Australia in vitrified form.
The working group recommends that ARPANSA monitors the situation and establishes appropriate advisory mechanisms at the time ANSTO applies for a licence to operate the [Reactor]. The working group requests that progress reports on this matter are tabled twice yearly at NSC [Nuclear Safety Committee] meetings.
The discussion at Part Seven is not inconsistent with the position taken by the working group. The points made are appropriate and I have no difficulty in accepting the recommendation."
59 The CEO noted, further, that the working group identified a number of problems with the management of spent nuclear fuel. The CEO said:
"I found the working group's discussion to be informative and challenging. It is not inconsistent with my discussion of the issues at Part Seven. The working group, however, reaches the conclusion that it 'is not able to conclude that the Applicant has, to date, demonstrated the overall strategy for managing spent nuclear fuel… is adequate'. I do not agree with this conclusion - my own view is that the strategy for reprocessing in France and return of the vitrified waste is safe and acceptable. The alternative of reconditioning in Argentina is reasonable, though I concede that it is underdeveloped at this point and subject to more stringent reservations."
60 In his conclusion (Part 13 - "Assessment and Decision") the CEO observed:
"The Act requires me to take into account 'international best practice in relation to radiation protection and nuclear safety'. During the assessment, the applicant has demonstrated that the radiation protection and nuclear safety objectives included as a part of the design meet those laid out in the guidance provided by the international authorities. The specific safety features of the design comply with those recommended in international guidance and applied in resent research reactor designs. The management of the design and construction project, including the codes and standards applied to the design and construction of systems important to safety, is consistent with management approaches and the codes and standards used for similar systems in reactors designed in other countries with strong safety systems. Finally, the designed outcomes for occupational radiation doses, discharges to the environment and consequent radiation doses to the public, and the likelihood of core damage are at least as good as those achieved in the design of modern research reactors."
