Japan−India Nuclear Cooperation Agreement

NM791.4415 Japanese prime minister Shinzo Abe and the Indian prime minister Nrendora Modi discussed a proposed Nuclear Cooperation Agreement during Modi's recent visit to Japan, but the two countries have yet to finalise the agreement. In addition to ongoing work to finalise a Nuclear Cooperation Agreement, the prime ministers affirmed their commitment to work toward India becoming a full member of the Nuclear Suppliers Group.1

Negotiations on a Nuclear Cooperation Agreement began in 2010 but they were suspended after the March 2011 Fukushima disaster. The resumption of negotiations was announced during a May 2013 meeting between Abe and India's then prime minister Manmohan Singh.

According to a former Indian ambassador, obstacles include Japan's insistence that no reprocessing of spent fuel would be done in India, and that in the event of a nuclear test by India, the components supplied would be immediately returned to Japan.2

According to Reuters, Japan wants more intrusive inspections of India's nuclear facilities to ensure that spent fuel is not diverted, and explicit Indian guarantees not to conduct nuclear weapons tests.3 Japan wants something stronger than India's self-imposed moratorium on weapons tests. India refuses to sign the Comprehensive Test Ban Treaty.

International Atomic Energy Agency safeguards apply only to that part of the nuclear program that India considers surplus to military ''requirements''. IAEA safeguards inspections in India will at best be tokenistic. For example a leaked IAEA document states: "The frequency and intensity of IAEA inspections shall be kept to the minimum consistent with the aim of improving safeguards." That is standard diplomatic jargon – it means that safeguards will be infrequent or non-existent except in circumstances where the IAEA wants to test novel safeguards technologies or procedures and India agrees to take part.4

It is likely that another complication is India's law regarding nuclear liability. The law does not completely absolve nuclear suppliers of responsibility in the event of nuclear accidents. Nuclear suppliers and their governments are seeking to avoid any liability whatsoever.

355 organisations in 22 countries have signed a petition calling for the Japan−India Nuclear Cooperation Agreement to be scrapped.5






Reactor restart debates

On September 10, Japan's Nuclear Regulation Authority (NRA) announced that it had approved Kyushu Electric Power Company's design and safety features for the two Sendai reactors. Kyushu received draft NRA approval in mid-July. Two smaller regulatory approvals remain before the Sendai plant can restart. The NRA said that it will now review the detailed design and construction of the reactors and related facilities, as well as operational safety programs and procedures for accident responses. These final stages could possibly be completed by the end of the year according to the World Nuclear Association.1

Once those steps are complete, the NRA would be able to issue its final approval for operation. Kyushu would also need to gain approval from political leaders in Kagoshima prefecture − though that is not a legal requirement. The federal government has the final say on whether nuclear power plants operate.1

Greenpeace said: "The decision really means that Kyushu Electric has moved restarting the Sendai reactors forward a bit, but it's still not a restart approval. It doesn't mean the NRA has certified the reactors as safe to operate or that they will restart anytime soon."2

Sendai, at the southern end of the island of Kyushu, is 50 kms from an active volcano. "No-one believes that volcanic risks have been adequately discussed," said Setsuya Nakada, a professor of volcanology at the University of Tokyo, in June.3 The inadequacy of evacuation plans, and the NRA's unwillingness to consider evacuation plans in its reactor restart decisions, is another bone of contention.4

The pro-nuclear governor of the prefecture where the Sendai plant is located and the mayor of Satsumasendai, the plant's host city, are likely to approve the restart of Sendai reactors, but many nearby townships are opposed. More than half of the 30,000 residents in Ichikikushikino, a coastal town 5 kms from the plant, submitted a petition mid-year opposing a restart.5

None of Japan's 48 'operational' reactors are currently operating; none have operated since the Ohi 4 reactor in Fukui prefecture was shut down on September 15 2013. Reactor restart applications for 18 other reactors have been submitted to the NRA.1

A Reuters analysis earlier this year concluded that fewer than one-third, and at most about two-thirds, of the 48 reactors will pass NRA safety checks and clear the other seismological, economic, logistical and political hurdles needed to restart. The analysis was based on questionnaires and interviews with more than a dozen experts and input from the 10 nuclear operators.6

According to Reuters: "Some reactors can essentially be ruled out, like Tepco's Fukushima Daini station, which is well within the Daiichi plant evacuation zone and faces near-universal opposition from a traumatised local population. Also highly unlikely to switch back on is Japan Atomic Power Co's Tsuruga plant west of Tokyo. It sits on an active fault, according to experts commissioned by the NRA. Twelve reactors will reach or exceed the standard life expectancy of 40 years within the next five years, probably sealing their fate in the new, harsher regulatory climate. These include reactor No. 1 at Shikoku Electric's Ikata power station. The outlook is less clear for about a third of the other 48 reactors."6

RBC Capital Markets analysts Fraser Phillips and Patrick Morton argued in June that 28 reactors − just over half − will be online by 2018.7 Similarly, energy industry consultant (and former CEO of Ontario Hydro International) Thomas Drolet, said in February: "I don't believe predictions that most of the 49 reactors will come back. My prediction is that about half of that, about 25, will eventually come back, gradually and carefully over the next five years. The basic rationale for that is some of the reactors, the Mark I BWR, may never get re-permitted in Japan. Secondly, some local governments just don't want them."8

Some government and industry representatives are openly discussing the permanent shut-down of ageing reactors. For example, Yuko Obuchi, the minister for economy, trade and industry, said in early September: "For myself, I would like to proceed with smooth decommissioning (of some plants) and at the same time the restart of nuclear power stations certified as safe."9 Kansai Electric Power Co. is one of the utilities considering that strategy. Kansai is considering decommissioning two ageing reactors at its Mihama nuclear power plant in Fukui Prefecture, but is intent on restarting two others at its Takahama plant in the same prefecture.10

Jeff Kingston, director of Asian Studies at Temple University's Japan campus, told Reuters in April: "I think the government is incredibly clever by doing the restarts in the most modern, advanced places that have the most local support and are yet far from centres of political activity. Then you use that to create momentum for the agenda of restarting as many reactors as possible."6

Some reports suggest that around a dozen reactors may be permanently shut down because they are either too old or too costly to upgrade.11 Twelve reactors began operation in the 1970s.12 A survey of utilities earlier this year by the Asahi Shimbun newspaper found that there was no near-term likelihood of restarting 30 reactors. Thirteen of those, mainly due to their age, are having particular difficulty in complying with the new standards according to the survey, and are likely to be decommissioned.10

Academics Daniel Aldrich and James Platte noted in an article in August: "By the end of 2020, 13 reactors will have reached the 40-year limit of their operating licenses, and an additional 10 more reactors will be 40 years old by 2025. Unless the NRA begins considering license extensions, it seems reasonable to assume that most of these older reactors will not restart. Thus, one could estimate that 25 to 30 reactors would restart in the next five years or so, and this does not account for newer reactors that the NRA or local governments could declare unfit for restart. While restarting some reactors will help generate revenue for Japan's struggling power utilities, the cost of decommissioning about half of Japan's pre-Fukushima reactor fleet will be significant. Despite the nuclear revival ambitions of the LDP and industrial leaders, Japan's nuclear sector appears to have a long, difficult road ahead of it."13
