8/3/2011 TSTF Technical Specifications Task Force A Joint Owners Group Activity ECCS Instrumentation B 3.3,5.1 BASES SURVEILLANCE REQUIREMENTS SR 3.3.5.1.4, SR 3.3.5.1.6, SR 3.3.5.1.7, and SR 3.3.5.1.8 A CHANNEL CALIBRATION is a complete check of the instrument loop and the sensor. This test verifies the channel responds to the measured parameter within the necessary range and accuracy. CHANNEL CALIBRATION leaves the channel adjusted to account for instrument drifts between successive calibrations consistent with the plant specific setpoint methodology.
The Frequency of SR 3.3.5.1.4 is based upon the assumption of a 92 day calibration interval in the determination of the magnitude of equipment drift in the setpoint analysis.
The Frequency of SR 3.3.5.1.6 is based upon the assumption of a 12 month calibration interval in the determination of the magnitude of equipment drift in the setpoint analysis.
The Frequency of SR 3.3.5.1,7 is based upon the assumption of an 18 month calibration interval in the determination of the magnitude of equipment drift in the setpoint analysis.
The Frequency of SR 3.3.5.1.8 is based upon the assumption of a 24 month calibration interval in the determination of the magnitude of equipment drift in the setpoint analysis.
Technical Specifications Task Force TSTF A Joint Owners Group Activity Examples of Recent Issues with TSTF-425 Adoption Submittals
" Staff Challenged the DAEC Categorization as an Administrative Change from TSTF-425
" Staff Viewed the Proposal not as a "Consolidation" but "Removal" of SRs (a Technical Change)
" Staff Cited §50.36(c)(3) as the Basis for Their Concern with the "Removal"
" DAEC Agree to Withdraw the Consolidation to Allow Continued Review of the LAR.
