S Nuclear Regulatory Commission Attention: Document Control Desk washington, DC 20555 South Texas Project Units 1 and.2 Dockets Nos. STN 50-498, STN 50-499 Conversion of the South Texas Project Technical Specifications to the Improved Standard Technical Specification Format.
On July 19,1994, Houston Lighting & Power briefed the Nuclear Regulatory Commision on its plan to convert the South Texas Project Technical Specifications to the Improved Standard Technical Specification format.
In this meeting, Houston Lighting & Power apprised the Nuclear Regulatory Commision of our intent to make the conversion and develop the necessary analytical documentation to reflect the unique design of the South Texas Project. This letter is to confirm Houston Lighting & Power's decision to implement a Technical Specification Improvement Program at the South Texas Project as follows:
(1)
The South Texas Project Units 1 and 2 Technical Specifications (TS) will be converted to the Improved Standard Technical Specifications format (including the bases) as documented in NUREG-1431 and as supplemented by applicable NUREG change packages.
This conversion will incorporate the applicable current requirements of the South Texas Project Technical Specifications into the format of the Improved Standard Technical Specifications except as noted below.
Houston Lighting & Power will provide the Nuclear Regalatory Commision with appropriate background information and justification for g
any NUREG requirements not incorporated.

The Sout.h Texas Project Units 1 and 2 are 4-loop Westinghouse oo units with 3-trains of Engineered Safety Features.
Since N
NUREG-1431 was developed for a plant with 2-trains of Engineered Safety Features, it is Houston Lighting & Power's m
&u understanding that South Texas Project will be the Lead Plant 80}]g Mnf for 3-train Engineered Safety Features conversion to Improved 7
Standard Technical Specifications. Houston Lighting & Power J will address the inconsistencies of NUREG-1431 as it applies f
0f to a 3-train Engineered Safety Features plant. The development

l Surveillance Intervals and Limiting Conditions for Operation and Associated Allowed Outage Times that provide for 1/3, 2/3 and 3/3 trains of inoperable equipment will be an integral part of the development of a Technical Specification for a 3-train plant.
Houston Lighting & Power recognizes that a.t l changes r:ust be appropriately supported by the necessary safety and accident analyses. The current Limiting Conditions for Operation, Allowed l
Outage Times and surveillance intervals in the South Texas Project Technical Specifications are the same as used in the standard 2-train Technical Specifications.
These times do not accurately reflect the advantages inherent in the South Texas Project design.
Houston Lighting Power will use probabilistic safety assessment (PSA) and other approved methods to establish appropriate Allowed Outage Times and surveillance intervals.
(3)
Houston Lighting & Power plans to perform the Improved Standard Technical Specifications conversion on the following general schedule:
o Complete draft specifications Oct 1995 e Submit License Amendment Request (LAR)
Feb 1996 e Projected Nuclear Regulatory Commision l
Approval of Improved Standard Technical Specifications Dec 1996 e Full implementation of Improved Standard Technical Specifications at South Texas l
Project Dec 1997 The Technical Specification Improvement Project will be implemented by a team consisting of individuals with licensing, operations, engineering and training backgrounds to ensure accuracy and to minimize the impact on South Texas Project operating organizations during the implementation process. Houston Lighting
& Power looks forward to working with the Nuclear Regulatory Commision staff on this important project and will request a meeting with the Technical Specifications Branch in the near future to further discuss the Technical Specification Improvement Project I
and schedule. Please contact us if you have any questions in the interim.
