TS 6.8.4.i, lnseryice Testing Program, requires the inservice testing of
ASME Code Class 1,2, and 3 components in accordance with the
ASME Boiler and Pressure Vessel Code.
ASME Code requires that l BCPSV-4425, the
RHR shutdown cooling common suction relief valve, a Class 1 valve, be tested every 24 months and that it open within a lift setpoint of +/- 3o/o of the specified code safety valve lift setting. Contrary to this requirement, on November 1, 2010,
PSEG identified that l BCPSV-4425 opened above the +/- 3% acceptable range. Since the valve was last tested on October 25,2007, this constituted a failed late surveillance test.
PSEG entered this issue into their
CAP as notification 20484572. This licensee-identified
NCV is of very low safety significance based on a Phase 1
SDP screening, because the relief valve lifted below the maximum rating of the piping. Thus, the condition resulted in the inoperability of the valve, but did not result in a loss of system safety function.
