SQil SI-606 Page 1 Revision 13 3ALANCE OF PLAtli TEMPERATURE MONITORING PRCCRAM 1.0 SCC 3E 1.1 This test consists of verifying the temperature of specific areas in aurillary building, diesel generator building, ERCH Oumoing sta: a. and main control room and to record condenser disenarge pressure on the operating MCR and EBR cn111er packages.

1.2 Recuirements 1.2.1 . Purpose - To verify the temperature at specific areas by visually reading and recording dry bulb air temoeratures are within limits as indicated on the data sheets. This is'to collect data for history of area temperatures where ESF equipment is located.

1.2.2 Purpose - To record condenser discharge pressure on the operating MCR and EBR chiller packages once a shift.

1.2.3 Tech Specs - None 1.2.4 Mode operability requirement - N/A 1.2.5 Performance Mode (s) - All 1.2.6 Scheduling - No concurrent SI's 1.2.7- Frequency - Once per shift.

1.2.8 Additional Manpower Requirements - 1 AVO (= 11/2 hrs per shift) ' '"

2.0 PRECAUTIONS 2.1 AVO should wait at each location until the temperature Indication has stabilized before recording the' temper'ature.

Revision 14 4.0 INSTRUCTIONS 4.1 Record on data sheet 1 the temperature at the locations listed on loca'eton sheet-1. Use a digital temperature indicator or thermometer to measure temperatures.

4.2 If any local temperature exceeds its limit as listed on data sheet -1, page 1, record out of Ilmit temperature every hour on data sheet -1, page 2 until temperatures are within limits.

Record time and temperature reading each hour. Notify the Shift Engineer the first time the reading is determined to be out of -

limits and notify the SE again when the temperature is determined to be withtr. limits.

NOTE: Should any local temperature exceed its limit, attempt a to restore temperature to normal. High temperature may be indication of failed venttiation and cooling systems.

4.3 Inspect the Main Control Room and Electrical Board Room Cht11er packages once per shift. Log compressor condenser discharge pressure and adjust this pressure to 160 psig to 240 plig by adjustment of the ERCW manual discharge TCVs at each chiller package. Opening the TCV will decrease pressure; closing the TCV will increase pressure. These TCVs will normally be  :

throttled according to operating pressure requirements of the chiller package. I,*

Notify the Unit one SRO If any chiller package cannot be adjusted to within ilmits.

ENCLOSURE 3 PROPOSED TECHNICAL SPECIFICATION CHANGE SEQUOYAH NUCLEAR PLANT UNIT 1 DOCKET NO. 50-327 (TVA-SQN-TS-88-20)

DETERMINATION OF NO SICHIFICANT HAZARDS CONSIDERATIONS O

e 1

i

l ENCLOSURE 3 I Significant Hazards Evaluation TVA has evaluated the proposed technical specification change and has determined that it does not represent a significant hazards considecation based on criteria established in 10 CFR 50.92(c). Operation of SQN in accordance with the proposed amendment will not:

(1) Involve a significant increase in the probability or consequences of an accident previously evaluated. The UHI system is designed to 1 supply additional inventory to the reactor core during the blowdown' phase of a LOCA. UHI flow to the core is terminated by automatic hydraulic isolation valves. These valves are actuated by level switches on the UHI water accumulator. The proposed change reflects a new actuation setpoint and the associated instrument tolerances for the level switches. As such, the change does not increase the probability of a previously evaluated accident. The new setpoint and tolerances were calculated based on a new level switch accuracy characteristic and a broadened UHI-delivered water volume band.

Broadening the delivered water volume band did result in increased PCTs for the limiting

  • cases. In all cases, however, the PCT remained below the 10 CFR 50.46 limit of 2,200 degeces F. This in turn ensures that offsite doses remain bounded by the analyses of FSAR section 15.5. Because the proposed setpoint ensures that the delivered water volume remains bounded by the new analytical limits, the proposed change does not increase the consequences of any previously evaluated accident.

(2) Create the possibility of a new or different kind of accident from any previously analyzed. The proposed change to the actuation setpoint and tolerances represents no modification to the UHI deslen

or operrilon, which could create a new accident. The change only affects the performance of UHI for accident scenarios in which it is alrea/> assumed to function.

(3) Involve a significant reduction in a margin of safety. The proposed change to SR 4.5.1.2.c.1 represents a new setpoint and accuracies for the combination of new level switches and a broadened delivered water volume band. The setpoint ensures U.at the delivered water volume remains between 850 and 1,130.5 cubic feet. Westinghouse analyses have indicated that delivered water volumes between those limits ensure that PCT remains below 2,200 degrees F. Therefore, the margin

safety is not reduced by this proposed change.
