Abstract

This paper describes development and demonstration of remote crawling systems to support periodic examinations of interim dry storage system (DSS) canisters for spent nuclear fuel in the USA. Specifically, this work relates to robotic crawler developments for "canister"based DSS systems, which form the majority population of DSSs in the USA for interim storage of spent nuclear fuel. Consideration of potential degradation of the welded stainless-steel canister in these systems is required for continued usage in the period of extended operation (PEO) beyond their initial licensed or certified terms. Challenges with performing the periodic examinations are associated with physical access to the canister surface, which is constrained due to narrow annulus spaces between the canister and the overpack, tortuous entry pathways, and high temperatures and radiation doses that can be damaging to materials and electronics. Motivations for performing periodic examinations and developing robotic crawlers for performing those examinations remotely will be presented, and several activities to demonstrate robotic crawlers for different DSS systems are summarized.

This paper describes activities performed with contributions by several organizations: • This paper describes activities sponsored at PNNL by the NRC under work agreement NRC-HQ-60-17-D-0006. PNNL is a multi-program national laboratory operated by Battelle Memorial Institute for the U.S. DOE under DE-AC06-76RLO 1830. • This paper describes research sponsored by EPRI. • The first demonstration inspection at Maine Yankee was sponsored by the Electric Power Research Institute. The second preapplication inspection was sponsored by the NAC Utility Technology Users Group (NUTUG) and work was performed by NAC International. Maine Yankee is a stand-alone ISFSI. • This paper describes inspection activities sponsored by Orano TN. • The Palo Verde Nuclear Generating Station of APS supported some of the activities described in this paper.
