Development of a honing tool for main steam isolation valve seats. Final report

Technical Report ·
OSTI ID:5349151
The main steam isolation valves (MSIV) of boiling-water reactor (BWR) nuclear power plants which fail the required periodic seat leak tests must be reworked to achieve leakage rates within allowable limits. ESD Corporation, under EPRI contract RP 1939-1, has designed, fabricated, and tested a portable valve seat honing tool for a 26-inch MSIV. Design specifications and test results are presented.
