20555 South Texas Project Units 1 & 2 Docket Nos. STN-458, STN-499 Deletion of Emergency Boration System
Dear Mr. Ross:
The Emergency Boration System injects borated water into the core to provide additional negative reactivity during a postulated steamline break accident. Analysis of the steamline break accident for the South Texas Project without the operation of the Emergency Boration System has shown that the NRC acceptance criteria can still be met.
Houston Lighting & Power described the deletion of the Emergency Boration System (EBS) in Amendment 2 to the FSAR on October 9,1978. A similar arrangement appears in RESAR-414 and the SER for RESAR-414 accepts the EBS deletion for that reference plant.
To date, we have received no germane questions concerning the EBS deletion.
Uncertainity in the NRC regulatory position is causing some difficulty in finalizing engineering and may cause some construction delays in the near future.
Therefore, HL&P requests clarification of this matter so that if the EBS is required, we will have some time to make the required backfits.
If you have any questions, do not hesitate to call Mr. Shawn S. Rodgers at (713) 676-3397.
Very truly yours, w
