Attachment 2 ST-HL-AE-4842 Page 1 of 4 Backaround Houston Lighting & Power submitted a request for an emergency Technical Specification change on May 20, 1992. The purpose of the change was to allow plant operation at power until a surveillance on the manual reactor trip circuitry could be performed during a shutdown of each unit. The NRC approved the change and issued License Amendment Nos. 37 (Unit 1) and 28 (Unit

2) on June 2, 1992.

Houston Lighting & Power subsequently performed the required surveillances in the fourth refueling outage for Unit 1 and the third refueling outage for Unit 2.

Houston Lighting & Power submitted a request for a one-time License Amendment on May 26, 1992. The purpose of the one-time amendment was to extend the inspection interval for the Unit 1 ,

turbine valves from 50 months, including the 25% grace period, to l approximately 52 months. The extension of the inspection _

interval was requested to allow inspection of the valves in the fifth refueling outage, which was scheduled to begin in February 1994. The NRC approved the request and issued License Amendment No. 40 on August 18, 1992.

Houston Lighting & Power subsequently performed the required inspections within the normal inspection interval during an unplanned outage in 1993. Houston Lighting & Power did not use the requested extension.

Houston Lighting & Power submitted a request for a one-time License Amendment on December 6, 1993. The purpose of the one-time amendment was to extend the allowed outage time for Unit 1 turbine driven auxiliary feedwater pump from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> _to 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br />. This time extension was requested to accommodate augmented testing for the turbine driven pump during restart of  !

Unit 1 from the 1993 Unit l' outage. The NRC approved the request and issued License Amendment No. 58 on January 25, 1994.

Houston Lighting & Power successfully tested the Unit 1 turbine 1 driven auxiliary feedwater pump, completed the_ Unit 1 outage, and returned Unit 1 to power operation in February 1994.

Attachment 2 ST-HL-AE-4842 Page 2 of 4 Descriotion of the Proposed Chance In accordance with 10CFR50.90, Houston Lighting & Power proposes the following changes to restore the Technical Specifications to the exact wording prior to the one-time amendments:

1. Delete the footnote in Table 4.3-1. This footnote required verification of the operability of the shunt relay trip circuitry for the manual reactor trip breaker function.
2. Delete the footnote in Technical Specification 3.3.4.

This footnote describes extension of the inspection interval for the Unit 1 turbine valves.

3. Delete Action c. in Technical Specification 3.7.1.2. ,

Action c. describes the allowed outage time for the Unit 1 Turbine-Driven Auxiliary Feedwater Pump during restart from the 1993 outage.

In addition, Houston Lighting & Power proposes the following editorial changes:

1. Add the Main Feedwater System limiting condition of operation to the Index.  ;
2. Remove note " (1) " from the " Reactor Coolant Flow--Low" functional unit in the Reactor Trip System Instrumentation '

table (3.3-1). Note " (1) " refers to Table 3.3-3, Engineered Safety Features Actuation System (ESEAS)

Instrumentation and the Reactor Coolant Flow instrument is not an ESFAS instrument.

3. Clarify the wording of the Action statement and .

Surveillance Requirements for the recirculation fluid pH ,

control system (3. 6. 2. 2 ) . The Limiting Condition for Operation specifies an upper.and lower limit for trisodium phosphate, but the-Action statement and Surveillance Requirements do not' reflect the. upper limit as clearly as possible.

4. Add the Unit 2 amendment number, Amendment 36, to the bottom of page 3/4 3-84, Technical Specification 3.3.4.

Page 3 of 4

5. Add a new page for Technical Specification 3.3.3.10, which is not used.
6. Change the term "EOC" to " EOF" on figures 5.1-1, 5.1-3 and 5.1-4. The " Emergency Operations Center" was renamed the

" Emergency Operations Facility" to clearly distinguish between the onsite emergency facility and the offsite county and state emergency facilities. This terminology is consistent with the current revision of the Emergency Plan.

Safety Evaluation The proposed changes remove the one-time amendments and return the Technical Specifications to the exact wording prior to the one-time amendments. Returning the Technical Specifications to their original wording is considered an administrative change because the actions that were related to the one-time amendments have been completed and the one-time amendments are no longer applicable. Removing the.one-time amendments make the Technical Specifications easier for the operators to use by removing action statements that are no longer applicable.

The other proposed changes are purely editorial and do not have adverse safety impact. The editorial changes do not affect the meaning or interpretation of any Technical Specification basis, Limiting Condition of Operation, Action Statement, or Surveillance Requirement.

No Sionificant Hazards Considerations Houston Lighting & Power has evaluated the proposed amendment against the criteria of 10CFR50.92 as follows:

1. Do the proposed changes involve a significant. increase-in the probability'or consequences of an~ accident previously evaluated?

The changes proposed to remove the one-time. amendments return the Technical Specifications to the exact wording prior to the one-time amendments. . Returning the Technical- i specifications to their original. wording is administrative I because the one-time amendments are no longer applicable.

Hence, removing the one-time amendments-would not increase ,

the probability or consequences of an accident. The other i changes are. purely editorial in nature, hence, would not .I increase.the probability or consequences of an accident.

- . . - . _ = -. -_.

Attachment 2 ST-HL-AE-4842 Page 4 of 4 Based on the above, removal of the one-time amendments from the Technical Specifications will not significantly increase the probability or consequences of an accident.

2. Does the change create the possibility of a new or different kind of accident from any previously evaluated?

The changes proposed to remove the one-time amendments return the Technical Specifications to the exact wording prior to the one-time amendmente. Returning the Technical '

specifications to their original wording is administrative because the one-time amendments are no longer applicable.

Therefore, removing the one-time amendments would not create the possibility of a new or different kind of accident. The other changes are purely editorial in nature, hence, would not create the possibility of a new or different kind of accident.

3. Does the change involve a significant reduction in a margin to safety?

The changes proposed to remove the one-time amendments return the Technical Specifications to the exact wording prior to the one-time amendments. Returning the Technical Specifications to their original wording is administrative because the one-time amendments are no longer applicable.

Therefore, removing the one-time amendments would not involve a significant reduction in a margin to safety. The other changes are purely editorial in nature, hence, would not involve a significant reduction in a margin to safety.

Environmental Imoact Analysis The proposed changes to the South Texas Technical Specifications have been reviewed against the criteria of 10CFR51.22 for environmental considerations. The proposed changes do not involve a significant hazards consideration; nor increase the types and amounts of effluents that may be released offsite; nor increase the individual or cumulative occupational radiation exposure. Therefore, the proposed Technical Specification changes meet the criteria given in 10CFR51.22 (c) (9) for a categorical exclusion from the requirement of an Environmental Impact Statement.

Implementation Plan Because the proposed changes are administrative in nature, Houston Lighting & Power does not request approval by a specific date. Houston Lighting & Power requests an implementation time of 31 days from the approval date to change and distribute appropriate documents.
