US surveillance database

The need for a material surveillance testing program to monitor changes in the properties of ferritic materials in the reactor vessel beltline region has been recognized since the beginning of the commercial nuclear power industry. In 1961, the American Society for Testing and Materials provisionally introduced ASTM E 185, Surveillance Tests on Structural 

The reactor in which the materials will be irradiated and the reactor for which the materials are being irradiated must have sufficiently similar design and operating features to permit accurate comparisons of the predicted amount of radiation damage. 

Each reactor must have an adequate dosimetry program. 

There must be adequate arrangement for data sharing between plants. 

3 or 5 based on predicted temp, shift and EOL fluence value

Resistance to commonly prescribed antimicrobials such as the penicillins and macrolides/azalides increased dramatically in the late 1980s through the middle to late 1990s. Table 68-2 provides resistance information collected nationally from 1999 to 2004 using the Tracking Resistance in the US Today (TRUST) surveillance database.26 In 2004, the average national rate of resistance to penicillin and macrolides was approximately 18% and 25%, respectively. Susceptibility results alone do not account for clinical success or failures when treating pneumonia. 

Abstract This chapter describes the surveillance database of the Western pressurized water reactor (PWR) reactor pressure vessel (RPV) beltline materials obtained from US, French and Japanese nuclear power plants (NPPs) and those from other countries, together with an overview of the characteristics of PWR RPVs. Trends of surveillance data which will be obtained in the near future and the possibility of new data from reconstituted and miniature specimen techniques are presented. 

PWR surveillance data from countries other than the USA, France and Japan are collected from open literature. There are several sets of PWR surveillance data other than US commercial reactor data in Appendix A to NUREG/CR-6551 (Eason et al., 1998). Table 4.14 shows PWR surveillance data from other countries from the NUREG/CR-6551 database.
