I SUMMARY OF FINDINGS Fort Calhoun Station NRC Inspection Report 50-298/99005 (DRP)

The report covers a 6-week period of resident inspectio The body of the report is organized under the broad categories of Reactor Safety, Emergency .

Preparedness, and other activitie Findings are assessed according to their potential risk significance and are assigned colors of green, white, or yellow. Green findings are indicative of issues that, while may not be desirable, represent little or no risk to safety. White findings indicate isNes with some increased risk to safety, which may require additional inspection resources. Yellow findings are more serious issues with higher potential risk to safe performance. No individual finding is indicative of either acceptable or unsafe performance. The findings are considered in total with other inspection findings and performance indicators to determine overall plant performanc Initiating Events

1R09 Inservice Testina Inspection Scope The inspectors observed the following tests:

.

OP-ST-FO-3001, " Diesel Generator 1 Fuel Oil System Pump Inservice Test"

=

OP ST-SI-3008, " Safety injection and Containment Spray Pump Inservice Test and Valve Exercise"

Testing was adequate to verify compliance with code requirements. All components met the acceptance criteri Observations and Findinas There were no findings identified and documented during this inspectio R10 Laroe Containment Valves Inspectio1 Scope The inspectors reviewed containment pressure relief release forms for January and February 1999. The licensee performs a weekly containment pressure relie Observations and Findinas There were no findings identified and documented during this inspectio R12 Maintenance Rule imolementation Inspection Scope The inspectors reviewed two equipment failures to verify maintenance rule implementation. Specifically, the insoectors evaluated the emergency response facility's computer system and West Switchgear Room Condenser Unit VA-90. The emergency response facility's computer pedorms the acquisition and displays technical data used to assist control room operators in evaluating the safety status of the plant. The west switchgear room condenser unit assists in providing cooling to safety equipment in the east switchgear roo The inspectors used the maintenance rule field flow chart and determined that the licensee properly dispositioned the failures, Observations and Findinas There were no findings identified and documented during this inspectio w ..

1R13 .- Maintenance Prioritization

a.' Insoection Scope The inspectors assessed the work controls implemented to minimize risk associated E with modifications being performed in the switchyard. The inspectors verified that the licensee had performed a safety assessment for the overall switchyard modification Additionally, when proposed switchyard activities placed the plant in higher risk configurations,' risk assessments were performed and the activity was required to be approved by the plant review committee prior to implementation.1 These activities'were !

( - property planned and controlled. ' Additionally, the inspectors verified that the licehsee d had properly evaluated the affect that the switchyard activities had on other planned online maintenanc . . b.-- Observations and Findinas There were no findings identified and documented during this inspectio R15L Ooerability Evaluations , insoaction Scope During surveillance testing, one of the control room air conditioning units failed to meet

- Test SE-ST-VA-0013, Control Room Air Conditioning Unit VA-46A Performance Test."

The actual air flow measured was 16,000 cfm. The inspectors reviewed the licensee's operability evaluation for. Control Room Air Conditioning Unit VA-46A and determined it

1EP1 Drill. Exercise. and Actual Events Inspection Scope The inspectors observed portions of an emergency preparedness drill. The primary focus of the inspection was to evaluate the licensee's classification, notification and protective action requirements, and development activities. The inspectors observed the licensee's critique of the emergency drill and determined it was self-critical in the identification of strengths and performance issues, Observations and Findinas There were no findings identified and documented in this repor OTHER ACTIVITIES l

!

The staff conducted an abbreviated review of Y2K activities and documentation using ]

Temporary instruction (TI) 2515/141, " Review of Year 2000 (Y2K) Readiness of l Computer Systems at Nuclear Power Plants." The review addressed aspects of Y2K )

management planning, documentation, implementation planning, initial assessment, detailed assessment, remediation activities, Y2K testing and validation, notification i activities, and contingency planning. The reviewers used NEI/NUSMG 97-07, * Nuclear UtiPty Year 2000 Readiness," and NEl/NUSMG 98-07, " Nuclear Utility Year 2000 i Readiness Contingency Planning," as the primary references for this revie Conclusions regarding the Y2K readiness of this facility are not included in this summary. The results of this review will be combii ed with reviews of Y2K programs at other plants in a summary report to be issued by July 31,199 ;
