ST-HL-AE-5114 Attachment A Page 1 ATTACllMENT A JUSTIFICATION FOR CBLA CLASSIFICATION Diesel Generator Special Test Execption Reference 2) requested a special test exception that will allow a 7 day essential cooling water system outage and a 21 standby diesel generator outage during power operations once per train once per cycle. The approval of this amendment will permit the removal of the essential cooling water system and standby diesel generator work from refueling outages. Relocating this work will save Ilouston Lighting & Power at least $5,000,000 over the life of both units.
Local Leak Rate Testing at Power Reference 5) requests an Appendix J exemption to allow the performance of selected local leak rate tests at power. The implementation of this exception will save at least $400,000 in avoided outage contractor manpower costs over the life of both units. This saving is realized by performing the required testing at power utilizing flouston Lighting & Power personnel rather than contractor personnel.
Horation Systems Flow Path Relocation Reference 6) requested relocating the boration systems flow path Technical Specifications to the Technical Requirements Manual. This is justified by the Final Policy Statement on -
Technical Specifications improvements for Nuclear Power Plants published by the Nuclear Regulatory Commission. Relocating this requirement will allow Ilouston Lighting & Power to revise it by the 10 CFR 50.59 process. A planned revision after relocation, which will make the requirements in the various Technical Specifications that constitute the boration system consistent, will provide the flexibility necessary to save at least $100,000 in avoided outage contractor manpower costs over the life of both units.
Chemical Detection System Relocation Reference 1) requested relocating the chemical detection system to the Technical Requirements Manual. This is justified by the Final Policy Statement on Technical Specifications Improvements for Nuclear Power Plants published by the Nuclear Regulatory Commission. Relocating this requirement permits llouston Lighting & Power to revise it by the 10 CFR 50.59 process. The changes llouston Lighting & Power will make to this requirement after re. location will save at least $100,000 in over the life of both units.

JUSTIFICATION FOR CBLA CLASSIFICATION PSV and MSSV Setpoint Tolerance Revision Reference 3) requested a setpoint tolerance revision for the pressurizer safety valves from 11% to *2% and the main steam safety valves from *1% to 3%. The safety analysis that supports this change was previously submitted as part of the documentation provided for Technical SpeciHcation Amendments 61 and 50. This will save at least $100,000 in avoided 1
manpower costs over the life of both units by climinating the expansion of the test sample when the "as found" setpoint is greater than 1%.
Core Exit Thermocouple Revision Reference 4) revised the number of core exit thermocouples required to be operable per quadrant for each channel. This will eliminate unnecessary plant shutdowns, emergency plant modiHeations, and emergency Technical SpeciHeation changes which will save at least
$100,000 in avoided manpower costs over the life of both units.
