  • Is Nuclear Power "Russian Roulette"? : Global Energy Policy Research
    risks Since the start of nuclear power generation in Japan in the 1960s more than 500 000 people have died in traffic accidents Even now close to 5 000 persons die per year but if we were to make it proportional to the numbers for nuclear power it would calculate to roughly 100 deaths per plant every year It should be clear which of the two is the riskier Russian roulette Now how do the global numbers look On this point international organizations such as the OECD are united in the conclusion that the energy source with the greatest risk per kWh is coal fired power generation Looking at GW years as the following chart shows the number of deaths for coal fired power generation is 6 9 persons while it is 0 048 persons for nuclear power This supposes the number of deaths from the Chernobyl accident at 31 persons but if we use the United Nations number of 60 persons it is 0 1 persons The risk of coal power is almost 70 times greater than that of nuclear power However in desperation Asuka et al include earthquake related deaths in their numbers and state that the magnitude of the risk of such a secondary disaster is enormous and a simple comparison to risks such as that of atmospheric pollution caused by coal fired power generation based on estimated increases in deaths due to illness etc is suffice to say meaningless This is sophistry If risks are not always simplified by abstracting their individual characteristics it is not possible to compare them quantitatively As the OECD also estimates it is irrefutable that tens of thousands of people around the world die every year as a result of direct damage from coal fired power generation This does not include damage from atmospheric pollution but as one can understand from looking at the recent PM 2 5 troubles the damage affects hundreds of thousands of people around the world every year In contrast the cause of the secondary disaster cited by Asuka et al was not radiation but rather the foolish crisis management by the Democratic Party government They also calculate the costs but as with former prime minister Morihiro Hosokawa they factor sunk costs such as past energy subsidies into future costs so it is not worthy of discussion The Democratic Party government calculated back end costs as well but even when these are included the cost of nuclear power rises only about 1 per kWh The cost of operating existing nuclear power plants is overwhelmingly cheap That said the cost of building new nuclear power plants is high The technical costs are low but this most recent accident has made the cost of safety measures immense Consequently building new light water reactors of the existing type in Japan is not prudent in terms of profitability The third generation light water reactors that this paper also touches upon are sufficiently safe but are disadvantageous from a cost perspective Until

  • Agora Conference "Considering Sustainable Energy Strategy" Report : Global Energy Policy Research
    fuel it is necessary to increase participation by the government and seek out a solution Takeo Kikkawa a professor at Hitotsubashi University who participates in government policy making as a member of the Fundamental Issues Subcommittee of the Advisory Committee for Natural Resources and Energy etc praised Dr Suzuki s assertions Regarding recent energy policy he indicated that the lack of reality is a problem Former Democratic Party policies such as advocating zero nuclear and the notion of returning to pre 3 11 policy held by some in the Liberal Democratic Party and METI are both problematic Ms Takeuchi indicated that there is a need to consider whether zero nuclear in the near future is possible She said In energy it is necessary to consider the Three E s of economics ecology and energy security The discussion on global warming countermeasures must also be promoted in coordination with other policies Hiroshi Tasaka representative of the SophiaBank think tank is known for his social commentary and entrepreneurial activities but he is an expert who has studied the final disposal of radioactive waste for 20 years He also advised the Kan administration on the response to the Fukushima disaster as a special advisor to the Cabinet He said that expansion of nuclear power must be prudent While geological disposal is possible from a technological standpoint we cannot find a place to do it We cannot secure public acceptance We must confront this reality he stated Furthermore the concept on NIMBY Not In My Back Yard I understand the necessity but don t build it in my back yard exists in every country including Japan If we had continued to conduct nuclear power generation safely in Japan and built trust we may have been able to make progress in the discussion on final disposal However in the wake of the Fukushima disaster it has been judged to be nearly impossible he indicated He further warned The irresponsibility that allows problems to progress without any serious self review is resulting in the distrust of the public The participants were unanimous that abruptly eliminating all nuclear power generation would be highly difficult They also predicted that with the legislation of the 40 year reactor decommissioning rule the proportion of energy produced by nuclear power would decline over the long term However opinion was divided In the current situation discussion of nuclear power generation becomes emotional No matter which direction you take you will run into a some kind of populism A long time will be necessary for the public to learn on their own stated Dr Tasaka In contrast Nobuo Ikeda chairman of the discussion and director of Agora Institute indicated We must resolve the problem that the discussion over the future of nuclear power urgently needs a solution In the current situation the cessation of nuclear power generation in Japan is incurring excess fuel costs of 10 billion per day Conclusion The Long Road to Restoring Trust A recurring point at the conference was

  • Nuclear is the ideal energy source, best for the environment and the world economy too — Only fear, ignorance and blind regulation stand in the way : Global Energy Policy Research
    while the road traffic and fire antis of the past had strong safety arguments on their side the nuclear antis of today do not Intense ionising radiation for example ultraviolet in bright sunlight can cause cancer and skin cancer is responsible for 30 deaths per year per million population 14 less than road traffic 110 per million 15 but more than fire 11 per million 16 and far far more than radiation from any nuclear incident To be true to their concern people worried about radiation should take their holidays by starlight or underground to protect their skin Fortunately most people are more balanced and simply avoid over exposure while enjoying their summer holidays with everybody else The truth is that nuclear radiation is unique only because it still carries the stigma in the public mind that it received during the Cold War But the propaganda picture of radiation from a nuclear holocaust is flawed The actual blast and fire from the bombs at Hiroshima and Nagasaki were a hundred times more lethal than the later effects of radiation as confirmed over the past 60 years by the health records of the survivors What about radioactive waste and terrorist nuclear threats These are only dangerous to the extent that radiation is dangerous If the dangers of radiation have been overestimated then waste is less of a problem A terrorist dirty bomb incident becomes mostly a matter of handling public panic and less of a radiation hazard as such Nuclear waste though nasty stuff does not spread or infect like fire or the disease that follows biological waste Because nuclear energy is so concentrated little fuel is used and little waste is created about a millionth as much as fossil fuel High level waste needs to be cooled reprocessed to recover the valuable unused fuel and then buried after a few years not too big a task But returning to the central question why is the gap the gulf between public fear and real danger from radiation so large Official public information relates to national safety regulations based in turn on international advice This ineptly recommends that nuclear radiation be kept as low as reasonably achievable ALARA Reports of recent work in toxicology have emphasised just how mistaken this principle could be 17 It is a simple attempt to appease public fear without reference to any risk Unfortunately regulations based on it have also set the scale of reaction to any accident evacuation food restrictions and public perceptions personal and social stress economic confidence Appeasement has not worked there has been great suffering without benefit the extra fossil waste emissions caused by closing nuclear power plants have added to the damage and the added safety costs of nuclear programmes have been a blind response to public phobia Personal testimony by senior safety professionals tells how dangerous industrial safety hazards are routinely accepted rather than incur miniscule radiation risks 18 19 Such are the consequences of the current dogmatic use of ALARA

  • The current state of promising research into extraction of uranium from seawater — Utilization of Japan's plentiful seas : Global Energy Policy Research
    adsorption material in Mutsu waters Taking into consideration that an increase in seawater temperature of 10 resulted in an increase in adsorption ability of 1 5 times it can be said that the improvements in the structure of the adsorption material improved contact efficiency with the seawater doubling performance Furthermore in small scale trials they achieved performance of 3 0 g of uranium per 1 kg of adsorption material over 30 days of immersion meaning that it was possible estimate adsorption performance over 60 days of at least 4 0 g of uranium per 1 kg of adsorption material As well in the anchoring method using the braided adsorption material a float is incorporated into the core of the adsorption material and it is anchored to the ocean floor so that the installed anchor does not present any obstacle until 40 m below the surface of the water giving it the advantage of not hindering navigation by boats except when immersed for collection as well as lacking susceptibility to the effects of waves even the tidal bore due to the characteristics of this anchoring method making it very feasible in terms of safety as well Remaining points at issue and coexistence with fishing and marine industries In a realistic consideration of this sort of extraction method one challenge is coexistence with the fishing industry that is to say it is feared that immersion of the adsorption materials will change the living conditions of fish As has been said the higher the water temperature the greater the adsorption efficiency of the adsorption materials so warm waters are desirable Therefore considering the main route of the warm Kuroshio Current it is evident that there are suitable locations such as the waters between Iriomote jima and Miyako jima the western waters between Okinawa and Amami Oshima between Tanegashima and Yakushima Hyuga nada Sea and Tosa Bay Fishing that would be disrupted by the anchored adsorption materials include fixed net fishing and fish farms Fishing methods that operate while in motion such as longline fishing trawl fishing gill net fishing and round haul net fishing are a challenge for the future but it is thought that they could be able to adjust to the waters where the adsorption materials are anchored As for communications and electrical cables on the ocean floor as they are not laid or pulled up frequently it is believed that they will be able to coexist with the adsorption material s anchors which would be pulled up every two to three months The next subject to consider is while they are able to coexist more and more with fishing and marine recreation and leisure the point of view of whether it will indeed be possible for them to guarantee energy resources Currently conservation and management of marine resources is carried out through efforts such as catch limits on fishing and resource recovery projects but as for the state of the marine resources in the oceans surrounding our country especially bioresources
