It has been called to my attention that the initial core inventory of yield of Cs-136 (169 MCi) as calculated by the British codes CACHE and WIMS (see section VI.2.2. "Chornobyl Unit-4 Core Inventory Calculation") is seriously in error. 1 Upon investigation, it appears the source of the error is in the codes: because Cs-136 is a special case (so-called shielded nuclide) and comes largely from the activation of Cs-135, only.a small contribution arises from fission. Apparently, the codes do not take this into account. Using the cumulative fission yield of the 136 mass chain yields an incorrect result since the chain terminates at the stable nuclide Xe-136 that, of course, does not decay to Cs-136. The initial inventory of Cs-136 in previous studies is estimated to be in the range of 2.2 to 3.6 MCi, so that a relatively good estimate should be about 3.0 MCi. It should also be noted that the assumption implied by the table that 1-131 and 1-133 have the same fractional release ...

New Developments in Atomic Energy Research
Undoubtedly, energy production and their sustained growth constitute a relevant factor for ensuring the economic and social development of any country. Considering the different available energy sources that the world can use to satisfy the foreseeable increase in energy demand in the coming years, particularly for the production of electricity, at least for the next decades there are only a few realistic options available to reduce further the CO2 emissions, to satisfy the foreseeable demand of electricity, and to have secure supply of energy. One of these options is the use of nuclear energy for electricity generation. If this is true, then, why the public opinion of several countries is against the use of this type of energy sources? One of the reasons is the negative impact of an accident in a nuclear power plant for the human beings and for the environment. The second reason is the possible military uses of certain nuclear installations used for the generation of electricity. The third reason is the nuclear waste generated by nuclear power plants.

This case study discusses the causes, consequences and implications of the nuclear disaster at Tokyo Electric Power Company's (TEPCO's) Fukushima Dai-ichi nuclear power plant that was triggered by a massive 9.0 magnitude earthquake and subsequent tsunami waves on March 11, 2011. There are two essential questions: First, "How could it have come so far?" Japan is rightfully considered a ...
The disaster that struck Japan's Fukushima Daiichi nuclear power station on March 11, 2011, caused the most extensive release of radioactivity since the Chernobyl accident in 1986 and was far worse than the 1979 Three Mile Island accident in the United States. Unlike at Chernobyl and Three Mile Island, the destruction at Fukushima was ...

As the crisis deepened, Prime Minister Naoto Kan secretly instructed Shunsuke Kondo, chairman of the Japan Atomic Energy Commission (AEC), to draw up a worst-case scenario for the nuclear accident. This contingency scenario was submitted to the prime minister on March 25, 2011. 1 It projected that the crisis could deepen in the following manner:

This study focuses mainly on the Fukushima nuclear disaster; however, it also addresses the consequences of the tsunami, as both of them influenced the impacts and emergency management. The great east Japan earthquake (GEJE), with a magnitude of 9.0, occurred off the north-east coast of Japan at 14.46 local time on 11 March 2011.
Japan, prior to the Fukushima accident in 2011, received approximately 30% of its electricity from nuclear power. Japan is mineral and energy poor and relies on imports for 84% of its total energy requirements.4. In addition to being a carbon-free generation technology, nuclear power has fewer fatalities compared to other energy sources (Figure 1).
