Annex B

Contingency Planning Report

Some of the salient points made in the report:

(i) Many nuclear power stations are located within a

few tens of kilometres of large centres of

population. Construction of the Daya Bay plant

some 50 km from the densely populated areas of Hong

Kong is therefore not a unique situation. [Table 1.1 on page 6]

(ii)

(iii)

Pressurized Water Reactors (PWRS), of the type to

be installed at Daya Bay, have never experienced an

accident that has resulted in a significant

radiological hazard to the public. [Chapter 4,

introductory paragraph, page 18]

With regard to any accidental release, weather and distance have a significant effect on the dispersion of radioactivity. [Table 4.1 on page 19]

(iv) The consensus of international opinion is that

beyond 25 kilometres there is only a need for monitoring and perhaps the control of foodstuffs. Plans for evacuation, sheltering and issue of stable iodine are not generally considered necessary. [Chapter 5, paragraph 5.1 and 5.5,

pages 25 and 28]

(v) The Hong Kong Government's existing organisation

for dealing with various natural disasters and other emergencies provides a sound foundation for the Daya Bay emergency organisation. A suggested structure for the response organization is given.
