CNSC Presentations at NRC-RIC 2010

Two senior officials of the Canadian Nuclear Safety Commission (CNSC) made presentations at the US Nuclear Regulatory Commission Regulatory Information Conference 2010 (NRC-RIC 2010) last week. The President of the CNSC, Dr. Michael Binder, spoke at NRC-RIC-2010 on A Canadian Regulator's Perspective on International Cooperation. He noted that there were now 48 CANDU-type power reactors in 7 different countries (plus 3 reactors under construction - 1 in Argentina and 2 in India). Emphasizing that national regulators have responsibilities toward customer countries, which he considered an international extension of Canada's safety mandate, he outlined the three phases of Canada's current engagement with the regulatory mechanism in a customer country: (i) With the national regulating agency in the buyer country (ii) On-site, at the end-use location of Canadian-origin technology (e.g. at the site of a CANDU reactor). (iii) Training of regulators as well as interactions at the university level. As the Nuclear Renaissance unfolds, he also indicated that the pattern of Canadian inernational regulatory engagement might move beyond bilateral engagements and evolve to encompass more multilateral mechanisms such as the Multinational Design Evaluation Program (MDEP), with greater harmonization of codes and standards and perhaps including a code of conduct for vendors of nuclear technology.

The Vice President of the CNSC's Technical Services Branch, Terry Jamieson took the theme of International Cooperation in Nuclear Regulation forward, speaking on the MDEP's Role in Converging Codes and Standards. He outlined the efforts of the Codes and Standards Working Group (CSWG) of the MDEP, and indicated that the present focus of the group was on the pressure boundary components. Although different countries had their own codes and standards regarding pressure boundary components, the American Society of Mechanical Engineers (ASME) codes were used as a basis for comparison, focusing first on Class I Pressure Vessels. The objective was to eventually evolve a harmonized set of standards (since full convergence was not found feasible). Next steps will focus on codes for Class I piping, pumps and valves, and later on codes for components beyond those at the pressure boundary.

Nuclear Regulatory Commission Regulatory Information Conference NRC-RIC-2010

The US Nuclear Regulatory Commission (NRC) will be holding its annual Regulatory Information Conference (NRC-RIC) from March 9 to March 11, 2010. The conference will bring together a variety of stakeholders in the nuclear sector with regulators and technical specialists, both from the NRC and from US national laboratories. While most attendees will be from within the US, there will also be a large number of attendees from other countries, including Canada, who will share their own experiences and provide their own insights into nuclear regulatory affairs.

Apart from plenary sessions addressed by NRC Chairman and Commissioners, there will also be technical sessions on a number of cutting-edge issues at the interface of regulation and technology. These include a session on Materials Degradation at the Containment and Reactor Coolant System Pressure Boundary [Audio], which will discuss probabilistic analysis tools for carrying out the assessment of materials degradation at the pressure boundary, incorporating insights from investigations of the Pressurized Thermal Shock phenomenon. This is expected to contribute, for example, to better understanding of the probability of leak before rupture of piping systems. There are also at least two technical sessions on international issues: one on International Coordination between countries pursuing New Nuclear Power, another on International Cooperation on New Reactors [including the activities of the Multinational Design Evaluation Program (MDEP)]. Another session is devoted to discussing regulatory applications of International Experience in Operating Nuclear Reactors.

A technical session on Regulatory and Policy Issues for Small Modular Reactors should prove particularly interesting - since there is now great interest in the possibility of constructing small and modular reactors (including for isotope production; research; and local, off-grid power or heat applications). [Audio of event].

A separate session discussing the interest in Small and Modular Reactors will also be held [Audio].There will also be a session devoted to new developments in Probabilistic Risk Analysis (PRA) for nuclear power plants, including a talk on peer review of the US NRC's SPAR (Standardized Plant Analysis Risk) model. [Audio]

There is also a session on technical, policy and R&D issues related to the licensing of the Next Generation Nuclear Plant (NGNP), a gas-cooled reactor currently under development. [Session; Audio]. This includes a talk on the US NRC's efforts to develop an evaluation model(EM) for the NGNP. Other sessions of interest include a poster session on Central and Eastern US Seismic Source Characterization (SSC) model development, which may have implications for characterizing seismic sources in Canada as well.

Overall, the conferences promises to be quite interesting indeed.

Update: The US NRC published a Commission Paper (SECY-10-0034) on Potential Policy, Licensing, and Key Technical Issues for Small Modular Nuclear Reactor Designs on 3-28-2010.

Canada: Nuclear Renaissance or Nuclear Vita Nova?

The Nuclear Renaissance has been a much-awaited thing in Canada, for at least the last four years, if not longer. Renaissance, of course, suggests the idea of 'rebirth', a beginning anew of a life once lived; with the subtext that things in this rebirthed life will be much the same as before, only newer.

Over the last several decades, the Canadian nuclear industry evolved to encompass three main sectors: Uranium Mining, Reactors for Power Production, and Radioisotopes for Medical Uses. Of these three, the reactor segment has had the greatest visibility, while, on a worldwide basis, it was actually the uranium mining and medical radioisotope segments which had the greatest relative market share. A 'renaissance' in the Canadian nuclear sector therefore came to be understood primarily in terms of new reactors, and new reactors essentially of the same CANDU pressure-tube configuration that Canada pioneered and which now are operating in many other countries as well.

But in his speech at the US Nuclear Regulatory Commission's Annual Regulatory Information Conference in March 2009, NRC-RIC-2009, the Deputy Director General of the International Atomic Energy Agency (IAEA), Mr. Tomohiro Taniguchi of Japan, speaking at the session on Global Perspectives on the Nuclear Renaissance, introduced a new phrase that he hoped would refocus the emphasis on new ways of doing things in the new nuclear age: Nuclear Vita Nova:

I, on the other hand, view this reality as a Vita Nova, or new life, because the nuclear community needs new ideas and innovative thinking to address new challenges, rather than a simple revival of the "good old days."

At the current juncture, when Nuclear New Build - which seemed imminent just a few months ago - has been indefinitely postponed in the main Canadian province; when the main Canadian reactor builder faces an uncertain future; and when the main private reactor operator in Canada has withdrawn its license applications for new nuclear reactors - it is certainly worth pondering what is in store for the Canadian nuclear sector - a Renaissance, or a Vita Nova? And if it is to be the latter, might the relative (and perceived) importance of the three main sectors change from what it was in the past? At the moment the answer is not clear, but the singular salience of the question must certainly be recognized.

(Dr. Taniguchi took care to mention at the end of his talk, for the benefit of those who might have missed the allusion, which, given his audience, was probably everybody - that his neologism 'Vita Nova' was actually the Latin form of the Italian La Vita Nuova, the title of a collection of verse that Dante Alighieri wrote in 1295, being an expression of the medieval genre of courtly love. Incidentally, the incoming Director General of the IAEA, beginning 01 December 2009, is also from Japan - Yukiya Amano. He will be taking over from Dr. Mohamed El-Baradei of Egypt, who has been named Director General Emeritus, an honor he shares with Dr. Hans Blix. Dr. Amano's appointment to the Director-Generalship of the IAEA will be ratified during the 53rd General Conference of the IAEA in Vienna, 14-18 September 2009. Like Dr. El-Baradei and Dr. Blix, Dr. Amano is also a lawyer. By coincidence, the current Director-General of ITER, Mr. Kaname Ikeda, and the current Executive Director of the International Energy Agency (IEA), Mr. Nobuo Tanaka, are also Japanese.)


Update: After I wrote this post, I discovered that on the TV Ontario program The Agenda, the season-opening episode on 8th September had been on Canada's Nuclear Future. I am pleased to embed the video, featuring an extremely spirited discussion (in which, as Steve Paikin, the host, quipped, they ran out of time but clearly not energy. The astute physicist reader of this blog will immediately see Steve Paikin's probably unintended pun here - since energy and time are classically canonically conjugate variables, they are related through a quantum uncertainty principle - the more precisely you bound one of them [in this case, time], the more uncertain the other will be!):
