judgement of the consultants, be required to take account of such features of the Daya Bay design as shall have been provided to the consultants. The significance of any such modifications will be commented on. Comment shall also be made on the relevance of such information about the Chernobyl accident as is generally available within the nuclear safety community by the beginning of the second phase.
a brief initial review of published data relating to the risks arising from external hazards, such as aircraft crash, flooding, earthquakes, hurricanes and tornadoes, for the Daya Bay power station.

Additionally arising out of the studies referred to above. the effects of food chain (terrestrial and aquatic) and liquid pathways will be assessed. It will not be possible to evaluate these pathways for all possible accident sequences and weather conditions, therefore a few key scenarios (ie. combinations of accident sequences and weather conditions contributing significantly to risk) will be identified for detailed

a comparison of the assessed risks (both in terms of magnitude and likelihood) with selected non-nuclear risks.
(iii) Upon submission of the report upon the work described in (ii) above,
the consultants shall liaise with the HKG concerning the production of a summary version of the report in which the reasoning and conclusions will be presented in a manner most likely to be intelligible and informative to non-technical readers, and shall thereafter, in the light of those discussions, write the said summary report.
