INSTRUMENTATION 3/4.3.6 CONTROL R00 BLOCK INSTRUMENTATION llMITING CONDITION FOR OPERATION 3.3.6. The ciint'rol rod block instrumentation channels shown in Table 3.3.6-1 ,
shall be OPERABLE with their trip setpoints set consistent with the values shown ja the Trip Setpoint column of Table 3.3.6-2.
APPLICABILfTYt As shown in Table 3.3.6-1. -
ACTION!
- a.
- With a control rod block instrumentation channel trip setpoint less
. conservative than the value shown.in the Allowable Values column of
- Table 3.3.6-2, declare the channel inoperable until the channel is restored to OPERABLE status with its trip setpoint adjusted consistent with the Trip Setpoint valua.
- b. With the number of 0PERABLE channels less than required by the Minimum .
OPERABLE Channels per Trip Function requirement, take the ACTION required by Table 3.3.6-1.
SURVEfLLANCE RE001REMENTS Each of the above required control rod block trip systems and ns rumentation channels shall be demonstrated OPERABLE
- by the performance of l the CHANNEL CHECK, CHANNEL FUNCTIONAL TEST, and CHANNEL CALIBRATION operations for the OPERATIONAL CONDITIONS and at the frequencies ,shown in Table 4.3.6-1.
4.34
- A channel may be placed in an inoperable status for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for required surveillance without piacing the trip system in the tripped condition, provided at
-least one other operable channel in the same trip system is monitoring that parameter.

- a. Verified closed at least once per 7 days.
- b. Demonstrated OPERABLE:
- 1. At least once per 31 days and within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> after any discharge of steam to the suppression chamber from the safety / relief valves, f by cycling each vacuum breaker through at least one complete cycle of full travel. c
- 2. At least once per 31 days by verifying both position Indicators OPERABLE by observing expected valve movement during the cycling test.
- 3. At leas r 24 months by: l a) Verifying - each valve's opening setpoint, from the closed 4 position, to be 0.5 psid
- 5%, and Onc e- b) Verifying both position indicators OPERABLE by performance of a CHANNEL CALIBRATION.
c) Verifying that each outboard valve's position indicator is capable of detectiig disk displacement a0.050", and each inboard valve's position-. indicator is capable of detecting disk displacement a0.120".

- b. By renewing occusatiated eater:
- 1) From the day tank at least once per 31 days and af ter each occa-sien when the diesel is operated for greater than I hour, and I) From the storage tank at least once per 31 days, e,
my sampling new fuel oil in accordance with ASTM D6057-41 prior to aeditlen to the storage tanks and:
- 1) ly verifying in accordance with the tests specified in ASTM Ug/5-31 prior to addition to the storage tanks that the sample has:
a) An API travity of within O.3 degrees at 60*F er a specific a
(M gravity of within 0.0015 at ge/50*F, een compared to the supplier's certificate or an absolute specific gravity at 80/80*F of greater than er equal to 0.83 but less than or equal to 0.89 er an Ap! eravity at Ge*F of greater than er eeuel to 27 degrees but less than er equal to se degrees.
b) A kinematic viscosity at 40*C of greater than er equal to 1.g contistakes, het less than er equal to 4.1 cantistokes, if gravity was not determined by camparisen with the supplier's certification, c) A flash point equal to or etwater than 125*F, 'and d) A clear and bright appearance with proper color when tested in accordance with AETM D4176-st,
- 2) By verifying within 31 days of ettai'iing the sample that the other properties 'specified in Table 1 of ASTM Dg75-81 are met when tested in accordance with ASTM D975-51 except that the analysis for sulfur may be performed in accordance with ASTM D1552-73 or ASTM DP622-82.
- d. At Toast once every 31 days by obtaining a sample of fuel oil free the storage tanks in accordance with ASTM Dat?6-7s, and verifying that total partit:ulate contamination is less than 10 mg checked in accordance with A5TM Ott76-7s, method A, exce/litar when pt that,the filters'specified in ASTM Dtt?6-78, Sections 5.1.E and 5.1.7, any have a nominal pere site of up to three (3) etcrons.
- e. At the following frequency by:
1.
Every la months sub.iecting the diesel to an inspection in accordance with procedures prepared in conjunction with its manufacturer's i
recommendations for this class of standby service.
2.
Every 24 months verify each diesel generator's capability to reject a lead of greater than or equal to that of its single largest post-accident lead wh1)r maintaining voltage at 4t85 s 420 volts and frequency at 60 a 1.2 ha and after steady state conditions are reached, voltage is maintained at 4280 e 120 volts.
