Turbine Generator Vendors

There are thirteen major companies who are currently designing and manufacturing large steam driven turbine generators, though only nine of these have supplied machines for PWR stations. After comparing the available information it has been concluded that five companies, GEC Turbine Generators, G.E., Alsthom, Westinghouse and Kraftwerk Union should be considered in detail for the Joint Venture.

Safety Standards

Since the joint nuclear power station will be a PWR, it is appropriate to refer mainly to the Safety Standards concerning design, construction and operation of those countries who have built and operated PWR power stations. In addition, because of the participation of GPC and CLP in the project, it is important

to give sufficient consideration to the concerns about nuclear power plant safety that may be expressed in Guangdong and Hong Kong and reference will also be made to the useful experience which is currently being gained within the United Kingdom on the assessment of the safety of PWR plant. Particular attention will also be paid to IAEA and ICRP recommendations.

The method of safety analysis that will be used for the joint nuclear power station 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 a Design Basis Accident (DBA) 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. All the potential reactor vendors should be capable of supplying plant to meet the required safety standards and will be able to assist GPC and CLP to prepare the necessary safety documents.

The joint utility will take responsibility for the safety of the nuclear power station under the guidance and inspection of the relevant authorities of the People's Republic of China.

Quality Assurance

An effective approach to quality assurance will be required throughout the manufacturing and construction period, both to ensure the general quality of all components used and specifically to meet the stringent safety requirements associated with the nuclear related plant.

In order to implement the overall quality assurance intentions, it is necessary that appropriately staffed quality assurance organisations and acceptable programmes exist in all companies involved in the project. The quality assurance organisation of the joint venture company will report directly to the appropriate engineering management and will undertake the surveillance of the quality assurance organisations. of all other parties. In this way the quality assurance organisation of the Joint Venture Company will take full responsibility for all aspects of quality at each stage of the project.
