Surveillance capsule programs are codified into federal law per U.S. Nuclear Regulatory Commission 10 CFR 50, Appendix H. The purpose of material surveillance programs are to monitor changes in the fracture toughness properties of ferritic materials in the reactor vessel (RV) under neutron irradiation. Surveillance capsules are withdrawn periodically from the RV, tested, and evaluated, and the results are reported following the guidelines laid forth in ASTM E185-82, Standard Practice for Design of Surveillance Programs for Light-Water Moderated Nuclear Power Reactor Vessels. This paper will focus on the Westinghouse AP1000® surveillance program because the combustion engineering and older Westinghouse programs have been extensively described in a previous publication.
