September 28, 1989 Docket No. 50-261 Mr. Lynn W. Eury Executive Vice President Power Supply Carolina Power & Light Company Post Office Box 1551 Raleigh, North Carolina 27602
Dear Mr. Eury:
SUBJECT:
QUESTIONS ON AUXILIARY FEEDWATER (AFW) SYSTEM, H.B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2.
Related to your recent investigation of the AFW system operability concerns at H. B. Robinson Steam Electric Plant, Unit No. 2, and the examination of the AFW pumps, we are interested in the effectiveness of the inservice testing program of the AFW system. Our concern about the IST program was discussed with Mr. R. Prunty of your staff on September 19, 1989 in a telephone conversation. Enclosed is a list of questions on the subject. We would appreciate your response to those questions within 45 days.
The reporting and/or recordkeeping requirements contained in this letter affect fewer than 10 respondents; therefore, OMB clearance is not required under P.L.96-511.
Sincerely, Orignal signed by Ronnie Lo, Senior Project Manager Project Directorate II-1 Division of Reactor Projects - I/II Office of Nuclear Reactor Regulation

Enclosure Questions regarding the inservice testing of the Robinson AFW Pumps
- 1. Provide a description of the inservice testing that is performed on the AFW pumps to include the frequency, flow path for each pump, and the parameters measured.
- 2. Provide a copy or listing of the data recorded during the IST of these pumps over the past twenty-four months.
- 3. Provide the design or safety analysis values for differential flow and pressure.
- 4. Assuming that the regular IST is performed using a minimum flow recirculation loop, provide the same information in questions 1 and 2 for any testing that may be performed at shutdowns or refueling outages at a higher flow rate.
- 5. Provide a description of the maintenance history of these pumps over the past five years.
