“…ITER safety requirement state that the dose rate at the port interspace (where maintenance is to be carried out) are required to be less than 100 Sv/h 10 6 s after shutdown [5]. In order to include the activated tokamak internals as a gamma source term in the shutdown dose maps a cylindrical surface source was generated at the cryostat which captured the gamma field from tokamak internals, based on SS304 steel activation.…”

“…Based on the second equation above, steam oxidation of 18 kg of beryllium will generate the 4 kg of hydrogen necessary to produce an explosion in an ITER-sized vacuum vessel that exceeds safety limits [23]. The beryllium multiplier inventory in a single TBM is over 10 times that amount (∼240 kg [24]); extrapolating to a full ceramic breeder blanket, it is apparent that such limits will be difficult to meet.…”

a b s t r a c tWater has both advantages and disadvantages as a coolant in conceptual designs of future fusion power plants. In the United States, water has not been chosen as a fusion power core coolant for decades. Researchers in other countries continue to adopt water in their designs, in some cases as the leading or sole candidate. In this article, we summarize the technical challenges resulting from the choice of water coolant and the differences in approach and assumptions that lead to different design decisions amongst researchers in this field.

“…These include the confinement of radioactive material to prevent releases in normal operation and in postulated accidents, the limitation of human radiation exposure, and the minimization of radioactive waste [1]. Nuclear analysis therefore has an important role in support of the licensing process.…”

“…This is essential to ensure a consistent approach with appropriate quality control. This has an impact on the licensing process (for more discussion of the licensing process see companion paper [1]). The co-ordinated nuclear analysis effort must satisfy the concerns of the French regulatory authorities and provide technical justification to support the ITER safety case.…”
