EXECUTIVE SUMMARY Bellefonte Nuclear Plant, Units 1 and 2 NRC Inspection Report 05000438,439/2010601 The inspection included aspects of engineering and construction activities, performed by Tennessee Valley Authority (TVA), associated with the Bellefonte Nuclear Plant (BLN), Units 1 and 2 project. This report covered a three-day period of inspections in the areas of quality assurance (QA); identification and resolution of problems; maintenance activities; engineering activities; access controls; and control of documents and records. The inspection was performed primarily under the guidance of NRC inspection procedure (IP) 92050, Review of Quality Assurance for Extended Construction Delay.
The inspection evaluated if TVA had properly implemented the NRC-approved QA program, adequately identified the status and quality of currently installed and stored equipment, and established processes and controls necessary to comply with regulatory requirements associated with its construction permits. The inspection evaluated the status of the applicable program areas, specified in Section III.A, Deferred Plant, of the Commission Policy Statement on Deferred Plants, through examination of procedures and representative records, interviews with personnel, equipment status verification, and observations of programs and processes. The inspection concluded that TVA activities remain within the guidelines established for a plant in deferred status, consistent with the Commission Policy Statement for Deferred Plants. The inspection results are discussed in detail below.
Inspection Results:
- Protection and preservation of plant assets through housekeeping efforts was appropriate for the status of the equipment. (Section 1)
- Proper procedural controls were developed for work and inspection activities conducted under the preventitative maintenance (PM) program. These activities were performed by qualified personnel using approved procedures. Associated documentation was found to be properly prepared, reviewed, approved, and distributed. (Section 2)
- The corrective action program (CAP) procedures were properly established. Audits and self-assessments to evaluate plant programs and processes were properly conducted and were of good quality. (Section 3)
Report Details Summary of Plant Status During the inspection period, BLN Units 1 and 2 remained in a deferred plant status, as defined by the Commission Policy Statement on Deferred Plants (52 FR 38077)
1.0 Plant Walkdowns a. Inspection Scope (92050)
Systems, structures, and components (SSCs) at BLN remain in an indeterminate status.
Therefore, the consideration of the safety classification of each individual SSC does not apply. However, certain assets that are typically considered important to safety were reviewed to evaluate the effectiveness of preservation efforts. The inspectors toured selected portions of the main control room, auxiliary building, reactor building, turbine building, and Unit 1 diesel generator rooms to review the condition of plant equipment.
During these tours, the inspectors reviewed the protection and preservation efforts including, control of groundwater intrusion, installation of protective coverings, weather protection, fire protection, proper housekeeping practices, and rodent control measures.
The following areas were inspected:
Unit 1 and 2 Turbine Building Unit 1 and 2 Main Control Room Unit 1 and 2 Reactor Building Unit 1 Primary Containment Tendon Gallery Unit 1 and 2 Diesel Fire Pump Room Unit 1 Diesel Generator Rooms, 1A and 1B Unit 1 and 2 Auxiliary Building Additional documents reviewed are listed in the attachment.
b. Observations and Findings No findings of significance were identified. The inspectors did observe significant humidity and ground water intrusion into the Unit 1 Primary Containment Tendon Gallery.
Upon discussions with the licensee, it was identified that this is seasonal and various mitigation techniques are being implemented to control this issue until a permanent solution can be implemented.
2.0 Preventive Maintenance Program a. Inspection Scope (92050)
The inspectors reviewed the PM program to determine the adequacy of the program for asset preservation and procedural compliance. Implementation of the preservation program relies on performance of many PMs that have been identified as necessary to protect plant assets. Examples of PMs performed under this program include system piping flushes, motor and pump lubrication verification, engine checks, component external inspections, and containment penetration pressure checks and humidity checks.
The inspectors reviewed specific PM requirements in the Bellefonte Maintenance Code Book, Revision (Rev). 94, and observed personnel performing PM activities. The inspectors reviewed procedural guidance and implementation of PM activities to ensure that procedures were readily available, current, approved, and followed. Additionally, when measuring and test equipment was required for PM performance, the inspectors reviewed the specific equipment requirements, including equipment checks, calibration, and use.
The inspectors reviewed documentation associated with various PM requirements that were completed by site personnel during the period January 2009 - June 2010. This included a review of applicable portions of the Bellefonte Maintenance Code Book which specified the PM requirements. The inspectors then reviewed the records for completed PMs to verify that procedural requirements had been satisfied and that actions had been initiated to address any discrepancies which were identified during performance of the PMs. Additionally, the inspectors reviewed documentation for selected PM inspection intervals to verify that they were performed at the appropriate frequency. The following PM activities were observed:
PM item number PM Codes Work performed 1NI-EPEN-034-A 177 Verify adequate nitrogen pressure and recharge if needed 1NI-EPEN-065-B 177 Verify adequate nitrogen pressure and recharge if needed 1NI-EPEN-027-B 177 Verify adequate nitrogen pressure and recharge if needed 1NI-EPEN-069-G 177 Verify adequate nitrogen pressure and recharge if needed 1NI-EPEN-061-B 177 Verify adequate nitrogen pressure and recharge if needed 1NI-EPEN-068-F 177 Verify adequate nitrogen pressure and recharge if needed 1NI-EPEN-059 177 Verify adequate nitrogen pressure and recharge if needed 1NI-EPEN-028-B 177 Verify adequate nitrogen pressure and recharge if needed ORF-VAAD-R49 614 Semi-annual standpipe system flush ORF-VAAD-R50 614 Semi-annual standpipe system flush ORF-MDSL-008/04 N/A Weekly Inspection Diesel Fire Pump
1NS-NAOH-SUMP 535 3 month inspection Sump NaOH tank room ONC-MCRS-001 284 Unit 1/Unit 2 Rx Vessel Inspection Additional documents reviewed are listed in the attachment.
b. Observations and Findings No findings of significance were identified. Site personnel have approximately 5000 scheduled PM items on an annual basis, with a majority of these PM items focusing on fire protection. The inspectors verified that proper procedural controls were used when performing PM activities and work was performed by qualified personnel. The inspectors also verified that adequate controls were implemented on measuring and test equipement to ensure that the equipment was properly controlled and calibrated. The inspectors did identify instances where verbatim compliance of certain PM activities, as prescribed by the Bellefonte Maintenance Code Book, was not possible due to the current status of the plant. While this does not violate regulatory requirements, the licensee acknowledged these observations in PER 237053 and is currently evaluating the resolution.
3.0 Corrective Action Program (CAP)
a. Inspection Scope (92050)
The inspectors reviewed Problem Evaluation Reports (PERs), interviewed personnel regarding their understanding of the CAP process and concerns resolution program (CRP), and attended daily meetings to ensure identified problems were appropriately classified and captured.
Specifically, the inspectors reviewed several PERs to verify that initiation level was appropriate, condition classification criteria were followed, management review and action was appropriate, and resolution of the issue was sufficient. The inspectors also reviewed an apparent cause evaluation report and a failure analysis report for a primary containment vertical tendon failure reported under 10 CFR 50.55(e). The inspectors assessed the licensees ability to determine the cause(s) of identified problems and consideration of the following: issue reportability, common cause, generic concerns, extent-of condition, and extent-of-cause. The review also assessed if the licensee had appropriately identified and prioritized corrective actions to prevent recurrence.
The inspectors reviewed the findings and recommendations from 11 internal audits and self-assessments, including items such as readiness for NRC inspection and corrective action follow-up. The audits and self-assessments were also reviewewed to verify they were performed with appropriate scope and frequency.
Additional documents reviewed are listed in the attachment.
b. Observations and Findings No findings of significance were identified.
4.0 Access Controls a. Inspection Scope (92050)
The team reviewed BLN procedure SSP-11.50, Bellefonte Security and Plant Access, Rev. 14, and interviewed personnel to verify the implementation of TVAs access control program. While not specifically required by the guidance in the Commission Policy Statement for Deferred Plants, the team recognized the potential effect on BLN current plant status if efforts were not in place to minimize unauthorized plant access.
b. Observations and Findings No findings of significance were identified. The team verified through witnessing entrance and exit requirements of both personnel and vehicles, that security measures were implemented in accordance with prescribed procedures.
5.0 Exit Meeting Summary The inspectors presented the inspection results to Mr. D. Pratt, General Manager, Bellefonte Nuclear Plant, and other members of management on June 30, 2010. No proprietary information was identified.
