BELLEFONTE NUCLEAR PLANT - NRC INSPECTION REPORT NOS.
50-438/03-01 AND 50-439/03-01
Dear Mr. Scalice:
On July 10, 2003, the NRC completed an inspection at your Bellefonte 1 & 2 reactor facilities.
The enclosed report documents the inspection results which were discussed on July 10, 2003, with Mr. M. Phillippe and other members of your staff.
The purpose of the inspection was to determine whether equipment preservation activities authorized by the construction permits were conducted safely and in accordance with NRC requirements. Specific areas examined during the inspection are identified in the report. Within these areas, the inspection consisted of selective examinations of procedures and representative records, interviews with personnel, and observation of activities in progress.
Based on the results of this inspection, no findings of significance were identified.
In accordance with 10 CFR 2.790 of the NRCs "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS).
ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/

SUMMARY OF FINDINGS IR 05000438-03-01, IR 05000439-03-01, on July 8 -10, 2003, Tennessee Valley Authority, Bellefonte Nuclear Plant, Units 1 & 2.
This annual inspection was to review the layup and maintenance of plant systems and the review of various plant records. This was an announced routine inspection conducted by a regional reactor inspector. Based on the results of this inspection no findings of significance were identified. The inspector concluded that, overall, the applicants layup and preservation program had been effective.
Report Details Summary of Plant Status Bellefonte Nuclear Plant (BLN) Units 1 & 2 remains in a deferred construction status as described in a July 14, 2000, Tennessee Valley Authority (TVA) letter to the NRC regarding confirmation of construction deferral status. The majority of piping systems remain in dry lay-up with the exception of fire protection related systems, chiller & associated support systems, and those systems required to support operation of the Unit 1 emergency diesel generators which are used as needed to assist in meeting temporary electrical distribution system peak load demand.
1.0 Quality Assurance a.
Inspection Scope (92050)
The inspector reviewed the applicability of an issue previously identified during a lay-up inspection for the TVA Watts Bar Unit 2 which is also in a deferred construction status.
Specifically, a finding was documented as a Severity Level IV violation in Watts Bar NRC Integrated Inspection Report 50-390/03-02 and 50-391/03-02. The Watts Bar finding involved a reduction of plant lay-up activities without a corresponding change to the applicants Nuclear Quality Assurance Plan (TVA-NQA-PLN89-A), or NQAP.
b.
Observations and Findings In reviewing the subsequent applicant corrective actions as delineated by Watts Bar problem evaluation report (PER) 02-016994-000, the inspector determined that the corrective actions developed for the Watts Bar issue would address any similar issues at BLN. No findings of significance were identified.
2.0 Plant Walkdowns a.
Inspection Scope (92050)
The inspector toured selected portions of the turbine building, auxiliary building, Unit 1 reactor building, Units 1 & 2 diesel generator buildings, and the intake pump structure to evaluate the lay-up and preservation condition of selected safety-related equipment.
During these tours, the inspector observed the proper operation of installed dehumidifiers and checked various safety-related components. Proper housekeeping practices and other control measures were verified to be in place. Selected safety-related components were checked by the inspector for external condition and protective covering, where necessary. Electrical motors and generators checked by the inspector were verified to be warm, with either internal heaters or heat tape energized. The following specific components were inspected:
- Unit 1 diesel generators 1A and 1B
Units 1 & 2 nuclear service water pumps and motors
Component cooling 2A pump and motor
Motor driven auxiliary feed water 1B pump and motor
Decay heat removal 1B pump and motor
High pressure injection 1B pump and motor
Reactor building spray 2B pump and motor
Unit 2 diesel generators 2A and 2B
Unit 1 reactor vessel head
Unit 1 hydrogen recirculation fan A
Unit 1 vital battery rooms b.
Observations and Findings The inspector noted that one battery cell, #47, was showing signs of impending failure (cell structure was buckled) on vital battery 1EU-EB-50-D. The applicant initiated work request 005577 to have the cell jumpered out and to perform general cleaning of the vital battery rooms due to the accumulation of acid corrosion.
No findings of significance were identified.
3.0 Preventive Maintenance Program a.
Inspection Scope (92050)
The inspector reviewed the applicant's Preventive Maintenance (PM) Program to determine adequacy of the program for maintaining systems in lay-up. Maintenance of the applicant's layup and preservation program relies on performance of PMs.
Examples of PMs performed under this program include motor heat verification, shaft rotation, component external inspections, system lay-up valve lineups and humidity checks. Specific PM requirements were specified in the BLN Maintenance Code Book, Rev. 93. Site personnel have performed approximately 12,000 to 15,000 scheduled PMs on an annual basis depending on the schedule requirements. The inspector reviewed the results of the applicant's program for verification of system dry lay-up by performance of drain valve checks and humidity checks. Verifications involved routinely opening drain valves at designated low points in each system to check for the presence of moisture. Humidity checks involved sampling system flow paths for relative humidity.
The inspector reviewed documentation associated with various PM requirements that were completed by site personnel during the period August 2002 - June 2003. This review included a review of applicable portions of the BLN Maintenance Code Book which specified the PM requirements. The inspector also reviewed completed PM records to verify that the PM requirements had been satisfied and that actions had been initiated to address any discrepancies which were identified during performance of the PM. In addition, the inspector reviewed documentation for selected inspection intervals of the PM activities to verify that the frequencies were performed on schedule.
Performance of the following PMs were observed:
- 0603-349, 1RT-EMOT-004-B, DG 1B aux lube oil pump motor
0703-847, 1NI-EPEN-071, Instrumentation penetration (pressure checks)
0703-622, 1NI-EPEN-073-A, Instrumentation penetration (pressure checks)
0703-384, 1NI-EPEN-075-A, Instrumentation penetration (pressure checks)
The following PM records were reviewed:
Component PM Codes Work Performed 1NO-MFAN-002-A, Hydrogen recirc fan 750 Rotate fan/motor shaft at least 15 turns with as left 90 to 180 degrees from as found position. Perform visual inspection of external/internal surfaces and clean as necessary.
