NOTATION USED IN TABLE 15.4.1-1 S-Each shift D-Daily W-W;ekly Q-Quarterly M-Monthly P-Prior to reactor criticality if not performed during the previous week. R-Each refueling interval (but not to exceed 18 months) PWR-Power and Low Power Operation, as defined in Specifications 15.1.h. and 15.1.n. HOT S/D-Hot Shutdown, as defined in Specification 15.1.g.1. COLD S/D-Cold Shutdown, as defined in Specification 15.1.g.2. REF S/D-Refueling Shutdown, as defined in Specification 15.1.g.3. ALL-All conditions of operation, as defined in Specifications 15.1.g, h and n. NOTES USED IN TABLE 15.4.1-1 (1) Not required during periods of refueling shutdown, but must be performed prior to reactor criticality if it has not been performed during the previous surveillance period. (2) Tests of the low power trip bistable setpoints which cannot be done during power operations shall be conducted prior to reactor criticality if not done in the previous surveillance interval. (3) Perform test of the isolation valve signal. (4) Perform by means of the moveable incore detector system. (5) Recalibrate if the absolute difference is 23 percent. (6) Verification of proper breaker alignment and that the 120 Vac instrument buses are energized. (7) Radic::tive Effluent Monitoring In:trun:nt: tion Surv;ill:ne: Requir:::nt: r: :p :!fied in S :ti:n 15.7.4. (8Z) Verify that the associated rod insertion limit is not being violated at least once per 4 hours whenever.the rod insertion limit alarm for a control bank is inoperable. (98) Test of Narrow Range Pressure, 3.0 psig, -3.0 psig excluded. Unit 1 - Amendment No. Page 5 of 6 Unit 2 - Amendment No.
v.s NOTES USED IN TABLE 15.4.1-1 (continued) (Mg) When used for the Overpressure Mitigating System, each PORV shall be demonstrated operable by: a. Perfomance of a channel functional test on_ the PORV actuation channel, but excluding valve operation, within 31 days prior to entering a condition in which the PORV is required operable and at least once per 31' days thereafter when the PORV is required operable. i (Hjj) Performance of a channel functional test is required, excluding valve operation. (MM)Shiftly check is required when the reactor coolant system is not open to the atmosphere and the reactor coolant system temperature is less than the minimum temperature for the in-service pressure test as specified in.TS Figure 15.3.1-1.- (M}2)An AFW flow path to each steam generator shall be demonstrated operable, following each cold shutdown of greater than 30 days, prior to entering power operation by verifying AFW flow to each steam generator. (M)))Calibrationistobeaverificationofresponsetoasource. (HQ) Sample gas for calibration at 2% and 6%. l (M}})A check of one pressure channel per steam generator is required whenever the steam generator could be pressurized. (Wi() Includes test of logic for reactor trip on low-low level, automatic actuation logic for auxiliary feedwater pumps, and test of logic for feedwater isolation on high steam generator level. (481?) Rod positions must be logged at least once per hour, after a load change >10% or after >30 inches of control' rod motion-if the on-line computer is inoperable. (491))The daily heat halance is a gain adjustment performed to match Nuclear Instrumentation System indicated power level with reactor thermal output. (2019)To confirm that hot channel factor limits are being satisfied, the requirements of TS 15.3.10.B must be mat. (M20) Check required only when the overpressure mitigation system is in operation. (M21)Not required during period of cold and refueling shutdowns, but must be performed prior to reactor criticality if it ~ has not been performed during the previous surveillance period. (M)$)Each train tested at least every 62 days on a staggered basis. (Mi3) Neutron detectors excluded from calibration. Unit 1 - Amendment No. Page 6 of 6 Unit 2 - Amendment No. .}}
