SEQUOYAH NUCLEAR PLANT 10 CFR 50.59 NRC ANNUAL OPERATING REPORT 1987 The following criteria establish the bases for the items contained in this report. I. Facility Changes A. Modifications The ECN Closure Group reports to Site Licensing the ECNs that have been closed for inclusion in the annual FSAR update. The same ECNs are reported in the annual operating report. Since the ECN Closure Group reports totally closed ECNs, and field complete ECNs were reported in previous annual operating reports, a cross-check was performed. Only the ECNs not previously reported are included in this report. B. Temperiry Alterations Temporary alterations to the facility are reported based , on how long the alteration has been in existence. Using ' the same criteria used for the FSAR update, an alteration will be reported if it has been, or is expected to.be, in existence for greater than one year. A temporary alteration is documented on a TACF. Previously reported alterations still in existence are listed by their TACF number only. New alterations meeting the above criteria are described and a safety I summary provided. i II. Procedures Technical specification surveillance instructions, abnormal l operating instructions, and emergency instructions have been determined to be as "described in the FSAR." Changes to these procedures are reported if they satisfied one or more , of the following criteria: l A. Procedure Changes Before May 20, 1987

SUMMARY

g ICF 87-135 clarified instruction step for measuring high voltage, added because the tolerance placed on RM-90-102 and -103 was too tight. This ! instruction step to clear att alarms before testing for motfunction stares, tolerance was established, because RM-90-102 and -103 are GM tute-type and corrected window rud;ers for RM-90-103 and -126, and block switch detectors. The +/- 25 volts high voltage value tolerance is adequate since - position for RM-90 126. the GM tube plateau curves are f airly constant at the calibrated high vottage setting. This change corrects errors made by ICF-87-135. These ICF 87-273 changed tolerance on the calibrated high voltage valve for changes ensure the SI can be performed the way it was written and do not radiation monitors RM-90-102 and RM-90-103 from "As Fotsid" +/- 10 volts and alter the margin of safety.

This was done to degrees Fahrenheit. If the flow rate that corresponds to 83 degrees decrease pressure of the ERCW side of the conpressor.

This will be accomplished by revising the SI-3 valves throttled to provide margin for ERCW ptmp degradation. ultimate heat sink tenperature acceptance criteria for that component, and SI-566 will require verification that the required SI-3 revision is the latest revision. (2) Flow acceptance criteria were revised to reflect instrument inaccuracies. (3) The ERCW flow to the auxiliary control air compressor was throttled with the upstream isolation valve instead of the downstream throttle valve. This action helped to ensure that the ERCW water pressure remained below the design pressure of the auxiliary controt air compressors. Any valve cavitation that occurred during testing was documented and dispositioned in this procedure. .The acceptable flow rate had a maxinun limit to minimize the ef fects of pressure and cavitation.

SUMMARY

g (4) The performance of SI-566 established a baseline for ERCW pump degradation by throttling the ERCW pupp discharge valves. 'This baseline is in the form of a flow rate differentist pressure, somewhere between 0 and 5 psid, depending on capability to meet the required ERCW flow rates. After the performance of SI-566, the procedure was revised to reflect this baseline differential pressure. White under balancing conditions, throttling the discharge valves to a differentist pressure of 5 psid resulted in an approximate 6-percent reduction of the total ERCW flow. To ensure that plant safety was not adversely affected by this pre-baseline throttling, the ERCW train was not tested if an ERCW component on the opposite train was not operable. Also, heat loads that could not be handled by the train under testing were transferred to the opposite train. These revisions did not increase the probability of an accident or malfunction, and the possibility for an accident of a d~fferent type was not created. The margin of safety, as defined in the basis of any T.S., was not reduced. l , I

SEQUOYAH NUCLEAR PLANT 10 CFR 50.59 NRC ANNUAL OPERATING REPORT 1987 The following criteria establish the bases for the' items. contained in this report. I. Facility Changes A. Modifications The ECN Closure Group reports to Site. Licensing the ECNs that have been closed for_ inclusion in the annual FSAR update. The same ECNs are reported in the annual operating report. Since the ECN Closure Group reports totally closed ECNs, and field complete ECNs were reported in previous annual operating reports, a cross-check was performed. Only the ECNs'not previously reported are included in this report. B. Temporary Alterations Temporary alterations to the facility are reported based on how long the alteration has been in existence. Using the same criteria used for the FSAR update, an alteration will be reported if it has been,-or is expected to.be, in existence for greater than one year. A temporary alteration is documented on a TACF. , Previously reported alterations still in existence are listed by their TACF number only. New alterations meeting the above criteria are described and a safety summary provided. II. Procedures Technical specification surveillance instructions, abnormal operating instructions, and emergency instructions have been determined to be as "described in the FSAR." Changes to these procedures are reported if they satisfied one or more of the following criteria: A. Procedure Changes Before May 20, 1987

1. Made a significant change to the scope, technique, or sequential order of steps affecting results or nuclear safety.
2. Waived or violated technical specification or licensing requirements.
3. Affected a quality control hold point.
4. Changed or revised the review / approval authority or responsibility.
5. Implemented a temporary alteration to operate CSSC equipnent.
6. Changed the acceptance criteria.

A summary of the safety evaluation for each procedure i change reported is included. B. Procedure Changes'After May 20, 1987 A USQD was. required for all procedure changes; prior to May 20, 1987. SQA-119 was revised on May 20,~1987, requiring a "screening' review" be performed to provide a record of review for changes to instructions, procedures, the radwaste system or facility, or test _and experiments proposed to be considered at SQN._ If the screening review determined a USQD was not required, the procedure is not reported. l

SUMMARY

g ICF 87-135 clarified instruction step for measuring high voltage, added because the tolerance placed on RM-90-102 and -103 was too tight. This instruction step to clear att alarms before testing for malfunction eteros, tolerance was established, because RM-90-102 and -103 are GM tube-type and corrected window numbers for RM-90-103 and -126, and block switch detectors. The +/- 25 volts high voltage value tolerance is adequate since position for fiM-90-126. the GM tube plateau curves are fairly constant at the calibrated high vottage setting. This change corretts errors made by ICF-87-135. These ICF 87-273 changed tolerance on the calibrated high voltage valve for changes ensure the SI con be performed the w3y it was written and do not radiation monitors RM-90-102 and RM-90-103 from "As found" +/- 10 volts and alter the margin of safety. The probability of an accident or malfunction "As left" +/- 2 volts to "As Found" +/- 25 volts and "As Left" +/- 25 was not increased. volts. The tolerance originalty specified is for scintittation-type detectors and does not apply to the GM tube-type detectors. Radiation monitors 90-102 and 103 are GM tube-type cetectors.

SUMMARY

(4) The performance of SI-566 established a baseline for ERCW punp degradation by throttling the ERCW pump discharge valves. This bt.4eline is in the form of a flow rate differential pressure, somewhere between 0 and 5 psid, depending on capability to meet the required ERCW flow rates. Af ter the performance of SI-566, the procedure was revised to reflect this besetine different?at pressure. While under balancing conditions, throttling the dischs.rge valves to a differential pressure of 5 psid resulted in en appro<imate 6-percent reduction of the total ERCW flow. .To ensere that plant se;fety was not adversely affected by this pre-baseline throttling, the ERC'J train was not tested if an ERCW component on the opposite train was not operable. Also, heat loads that could not be handled by the train under testing were transferred to the opposite train. These revisions did not increase the probability of an accident or malfunction, and the possibility for an accident of a different t p was not created. The margin of safety, as defined in the basis of any T.S., was not reduced.
