Abstract
The primary challenges associated with Light Water reactors stem from the degradation of stainless steel structural components during long reactor lifetimes. One problem in particular is the in-situ measurement of swelling and changes in modulus over the core lifetime. Lambda Instruments, Inc. proposes to develop extremely high-temperature, radiation-hardened fiber optic sensors based on their unique sapphire waveguide technology. Sapphire is an inherently high-temperature material and has been shown to retain acceptable transmission properties in moderate radiation environments. Project Outline: (Phase I) This is a feasibility study that will address sensor survivability in high radiation environments. Specifically, initial tests at the OSU TRIGA reactor will be designed to simulate future testing at the ATR facility at INL; (Phase II) This phase will be focused on finalizing test plans and procedures with the goal of completing initial testing in the ATR by the conclusion of Phase II. Sensor designs will continue to be improved and ruggedized; (Phase III) We will leverage commercial contacts with General Atomics, Westinghouse and others developed during the first two phases to generate/solicit commercial funding to continue work. Commercial Applications and Other Benefits: Beyond the nuclear reactor market, there is a significant commercial market in conventional power production. Initial target markets will focus on industries such as fossil fuel energy where there is a similar need for high-temperature instrumentation.
