Evaluation of reliability data sources in China

The paper first reviews the development of probabilistic safety assessment in the last few years in China. We have done the following work: (1) Training and improving the personnel's capabilities of performing PSA. (2) Organizing activities for putting emphasis on solving the PSA problems for Qinshan and Guangdoing NPPs. (3) Working out the project for setting up the Reliability Data Bank in the Research Institute of Nuclear Power Operation. Secondly, the paper introduces a plan on the development of PSA in the Research Institute of Nuclear Power Operation in the near future. The plan includes: (1) Investigating and translating the information from abroad so as to continuously train personnel's capabilities. (2) Importing part of the applied analysis procedure and putting into computer-M240D. (3) Sending some people to Qinshan NPP to attend the commissioning there for collecting operating data. (4) Setting up the Reliability Data Bank. (5) Developing the analysis model and multifunction computer code and improving PSA methodology. The paper finally expresses our hope to co-operate and exchange experiences with other countries in the field of PSA technology. (author)
