Approved:
-. Barnes, Chief. Materials and Qpplity Dete Programs Section, Division of R# actor Safaty Inspection Summary Inspection Conducted February 27 throuah March 3, 1989 (Report 50-313/89-08)
Areas Inspected: Routine, unannounced inspection of the inservice testing (IST) program for pumps and valves.
Subject activities reviewed in this area of the inspection included a followup review of the Unit 1, IST program relief request submittal to NRR, IST test results trending of pumps and valves. IST check valve disassembly program, and witnessing the quarterly operability test performed on Reactor Building Spray Pump P-358.
In addition, the NRC inspector reviewed actions taken regarding previously identified inspection findings.
Results:
In general, the licensee's second 10-year IST program for Unit 1 appears to meet ASME Section XI Code Requirements.
It should, however, be noted that technical issues regarding IST Program relief requests have been identified and documented in NRC Inspec'. ion Report 50-313/88-47.

Followup on Previously Identified Inspection Findings (92701)
'
(Closed) Open Item (313/8737-01): Once-through Steam Generator (OTSG) - Lower 5 Inch Weld Handhole - Gasket Leakage.
During this inspection, the NRC inspector reviewed the licensee's root cause determination (OAG880033) dated November 1, 1988, the corrective actions initiated'for short-and long-term repairs, and preventive maintenance.
It was observed by the NRC inspector that the licensee has taken responsive and reasonable actions in attempting to correct the generic problem of small leaks at the steam generator manway and handhole flanges.
This matter is considered closed.
(Closed) Open Item (313/8737-02):
Inspection and acceptance criteria established for manway and handhole flange assemblies on the OTSG. During
!
the exit meeting on October 30, 1987, the licensee committed to
incorporate a visual inspection of OTSG flange assemblies into the j
Preventive Maintenance Program.
During this inspection, the NRC inspector i
reviewed PMEE-099, " Tanks, Vessels and Heat Exchangers," dated
'
December 31, 1987, and verified that visual inspections are to be conducted on an 18-month interval and a disassembly inspection each 90 months. This matter is considered closed.

Inservice Testing (IST) Program-Pumps and Valves (73756)
The objectives of this inspection were to witness the implementation of i
the ANO, Units 1 and 2, functional testing of pumps and valves as prescribed by the Units 1 and 2 IST programs and to assess the adequacy of the testing performed with respect to the requirements of Section XI of the ASME Code.
a.
Follow On Review - IST Program During a previous inspection (50-313/88-47, February 7, 1989) several technical issues were identified by the NRC inspectors relative to
the licensee's second 10-year S terval IST program plan submitted for Unit 1, on October 20, 1988. During this inspection, the NRC inspector inquired as to the status of these issues.
In discussing this subject with the cognizant engineering programs supervisor, the NRC ' inspector was informed that, as a result of the AN0 organizational structure, no individual has the overall responsibility for coordinating the IST programs for each unit.
Surveillance test scheduling and functional IST test performances are implemented through station testing procedures performed by the operations staff for each unit.
Engineering and technical issues are assigned to different individuals, or groups, through the licensing staff personnel.
In order to establish a status of outstanding IST issues, each of the individuals, or groups, would have to be contacted separately.
The NRC inspector found that because of other assigned duties, work loads, and limited responsibilities of the specific individuals, information regarding the status of outstanding issues regarding the IST program was not available during this inspection.
The NRC inspector expressed concern to the cognizant licensee representatives and was advised that AP&L is embarking on a reevaluation of the current administrative organizational structure of the IST program, giving due consideration to limiting individual work loads, thereby enhancing the IST program.
b.
Observation of IST Testing During this inspection, the NRC inspector accompanied AP&L operations personnel in observing the following component IST functional tests:
Unit 1
" Reactor Building Spray-P35B Quarterly Test," Test Procedure 1104.05, Supplement 5, including stroke time for Check Valve CV-3805 and verification of flow for Check Valve BW-6B.
" Reactor Building Spray Train "B" Leak Determination,"
Procedure 1305.04, Supplement 2.

Safety System Diagnostic Instrument DCP-86-1005. Calibration Verification Procedure 1409.116. "SSDI Reactor Building Spray Pump Indication." Calibration dated October 27, 1988.
Unit 2
" Diesel Generator 2DG2 Monthly Test, Procedure 2104.36,
Supplement 2, including stroke time for service water outlet Valve 2CV-1504.2.
" Emergency Feedwater System Operations," Procedure 2106.06, Supplement 1, Monthly Pump Test on turbine driven Pump 2P7A, including flow verification 2EFW-7A, -8A, -9A, and -9B.
The NRC inspector observed that each test was
' ducted by a shift reactor operator in complete control of each sit of the applicable test procedures.
Procedure steps were sequentially performed and pertinent data recorded as required. Calibration dates of test
equipment were verified and acceptance criteria were clearly defined.
No violations or deviations were identified.
c.
IST Trending During this inspection, the NRC inspector reviewed the licensee's IST component trending program log for Units 1 and 2.
The NRC inspector observed that accumulated data was current with the chronological testing status and should provide the ability to detect component degradation.
.
No violations or deviations were identified.
4.
Exit Interview The NRC inspector met with the licensee personnel denoted in paragraph 1 on March 3, 1989. The NRC inspector summarized the inspection scope and findings. No information was presented to the NRC inspector that was
identified by the licensee as proprietary.
