, a INTERIM REPORT - DER 83-61 POTENTIAL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNIT 1 I. Potential Problen LPSI pump 'B' (1MSlBP01) has failed to start on three different occasions and has been disassembled and inspected under Ingersol-Rand supervision on each occasion. Project DER 83-21 was previously issued and dispositioned in regard to this condition.

DER 83-61 was initiated as a result of NCR SM-2156 which documents that LPSI pump 'B' has again failed to start as required by the operability requirements specified in the purchase specification.

NCR SM-2756 documents that during Preoperational Test 91PE-1SI-8 the Low Pressure Safety Injection (LPSI) Pump, IMSIAP01, had actual Total Head of 315 ft. compared to the required 335 ft.

NCR SM-2757 documents that during Preoperational Test 91PE-1SIO8 the Low Pressure Safety Injection (LPSI) Pump, IMSIBP01, had an actual Total Head of 297.7 f t. compared to the required 335 f t.

II. Approach To and Status of Proposed Resolution Bechtel engineering has received correspondence ~f rom C-E (V-CE-18979) providing disposition and technical justification for corrective action concerning Unit 1 LPSI pumps. However, recent testing on Unit 2, revealed LPSI pump "A" has experienced similar re starting problems as Unit 1 LPSI pump "B". Based on this new condition, DER 83-61 will be revised and an extension of time is requested for investigation of the LPSI pump problem.

III. Projected Completion of Corrective Action and Submittal of the Final Report Evaluation of this condition and submittal of the Final Report is Forecast to be completed by January 26, 1984.
