CONCLUSIONS
Based on the findings of the four Sub-committees it is concluded that the development of a nuclear power station of approximately 2 x 900 Mwe capacity in Guangdong Province jointly by GPC and CLP through HKNIC is both feasible and highly desirable.

On
the grounds of operating experience, overall costs and considerable world-wide programme on safety evaluation, the most suitable type of reactor for a nuclear power station in Guangdong would be the Pressurised Water Reactor (PWR).
Extensive studies of the Guangdong and Hong Kong power systems show that it is technically and economically feasible to accommodate nuclear power station of approximately 2 x 900 Mwe capacity in the late 1980's. It is also feasible to construct a 500/400 kV transmission system for power transfer from the nuclear power station to the Guangdong and Hong Kong power systems.
The supply of nuclear fuel to the nuclear power station should be reasonably secure, as nuclear fuel would gradually be supplied by China after an initial period of supply by reactor manufacturer.
The Tun Yang and Dong Shan sites are satisfactory in meeting technical requirements for construction of a PWR nuclear power station. Based on a series of site investigations, it is found that both sites can satisfy the technical requirements regarding environmental safety, geology, seismology, hydrology and meteorology, access
and
transportation. of the two sites. CLP favours Dong Shan it is more remote and screened from Shenzhen and Hong Kong by a range of mountains.
as
The selection of equipment and nuclear fuel suppliers should be on a basis of no requirement for nuclear inspection and an offer of technically sound and reliable plant which is competitive in price and supported by favourable loan conditions. A guaranteed long term supply of fuel will be required.
The safety standards to be adopted for the nuclear power station, apart from complying with the regulations of the People's Republic of China, will reter to the relevant standards and recommendations of the IAEA and ICRP, the standards of countries with operational experience of PWR power stations and the relevant experience which is being gained in the U.K. on the assessment of the safety of PWR plant. The method of safety analysis that will be used will draw on the experience existing in other countries at the time licensing is undertaken in Guangdong. At the present time, it is envisaged that the method adopted will mainly be based on the design basis accident approach, with use of the event or fault tree analysis method to give additional verification that there will be no unacceptable risks to the
environment.
