Dear Mr. Tedesco:

E rNI[D A //

South Texas Project 4 f 9, Units 1 & 2 ~

Docket Nos. STN 50-498. STN 50-499 Long Term Operability of Deep Draft Pumps By letter dated March 17, 1982, your office submitted to Houston Lighting

& Power Company (HL&P) some guidelines regarding the demonstration of operabil-ity of deep draft pumps. In addition, HL&P was requested to provide a schedule indicating when a response, in the form of an amendment to Final Safety Analy-sis Report (FSAR) Section 3.9.3, will be provided that discusses HL&P's assur-ance program for demonstrating long tenn operability of the deep draft pumps utilized on the South Texas Project (STP) and the extent to which STP conforms to the various protions of the guidelines.

HL&P and our architect-engineer, Bechtel Power Corporation (BPC), have reviewed the information contained in your letter and compared this informa-tion against HL&P's previous response to NRC Inspection & Enforcement (IE)

Bulletin 79-15, " Deep Draft Pump Deficiencies." We have concluded that, in light of the NRC guidance document. there are no deep draft pumps that fall into the 30 to 60 feet description in the guideline. This assumes the pump as being measured from the top of the coupling housing to the bottom of the ,

suction bell (it should be emphasized that typically the driver or motor is  !

not considered as being integral with the pump). Based upon this inter-pretation, the pumps utilized on STP range from 21 to 27 feet in length.

As previously stated in our response to the subject Bulletin, there are no vertical turbine (deep draft) safety related pumps manufactured by Ingersoll-Rand, Bingham - Willamette or Byron Jackson utilized on STP.

diouston.Ughting & Pbur Qxnpany April 19,1982 ST-HL-AE-816 SFN: C-0630/C-0510 Page 2 Our architect-engineer will incorporate the NRC guidelines into their f

transition phase activities and will, as necessary, recommend that those procedural or testing requirements which will provide added assurance that the subject pumps will perform their intended functions be incorporated as a result of their review. This review will be completed such that any additional requirements can be identified and any necessary amendment to the FSAR completed no later than 18 months prior to fuel load.

If you should have any questions concerning this item, please contact Mr. Michael E. Powell at (713) 877-3281.

Very truly yours,
