Evaluation of snubber functional test methods: Tier 1. Final report
- Lake Engineering Co., Greenville, RI (United States)
The objective of the research is to establish technical bases in support of efforts on the part of the Snubber Utility Group (SNUG) and the Subsection ISTD Working Group of the ASME O&M Code in developing guidelines and methodologies for snubber functional testing to ensure that snubbers are tested in a manner that ensures reliable and meaningful test results. The methodology used in this research includes both a review of available industry information as well as the testing of different snubber models using various test machines. Information is provided pertaining to current industry practices in regard to snubber testing including recommended test procedures, technical description of various test machines, and the number and types of snubbers used in the nuclear power industry. A review of previous test methodology research conducted by the Snubber Utility Group is also included. The effects of variations in controllable test parameters on snubber test results are discussed. Also included are the results of confirmatory tests in which various snubber models were tested using various test machines. Recommendations are provided for standard test methods to be included in Subsection ISTD of the ASME O&M Code [4]. General information and recommendations are provided that may be used by utility personnel in specifying snubber test equipment that is most suited for plant-specific needs as well as information that may be effectively used in the review and interpretation of test results.
