UNITED STATES NUCLEAR REGULATORY COMMISSION ary 6, 2012
SUBJECT:
BELLEFONTE NUCLEAR PLANT - NRC INSPECTION REPORT NO.
Dear Mr. Skaggs:
On December 1, 2011, the NRC completed an inspection at your Bellefonte 1 reactor facility.
The results of the inspection were discussed with Mr. Hruby and other members of your staff.
The enclosed report presents the results of that inspection.
The purpose of the inspection was to determine whether activities authorized by the construction permits were conducted safely and in accordance with NRC requirements. 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 the inspectors did not identify any findings of significance.
In accordance with 10 CFR 2.390 of the NRC's "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).

EXECUTIVE SUMMARY Bellefonte Nuclear Plant, Unit 1 NRC Inspection Report 05000438/2011602 The inspection included aspects of engineering and construction activities, performed by Tennessee Valley Authority (TVA), associated with the Bellefonte Nuclear Plant (BLN), Unit 1 project. This report covered a two-day period of inspections in the areas of quality assurance (QA); identification and resolution of problems; and subsurface geology. The inspection was primarily performed using the guidance in NRC inspection procedures (IP) 45051, Geotechnical/Foundation Activities Procedure Review, IP 45053, Geotechnical/Foundation Activities Work Observation and 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 associated processes and controls necessary to comply with regulatory requirements associated with its construction permits.
Inspection Results:
- The observed portions of the Component Cooling Water system walked down were conducted in accordance with approved procedures and the results were appropriately documented. (Section 1)
- The portions of the subsurface investigations reviewed were conducted in accordance with approved procedures and the investigation results were appropriately documented.
(Section 2)
- The portions of the subsurface investigations reviewed met applicable QA requirements and the results were appropriately documented. (Section 3)
Report Details 1.0 Plant Walkdowns a. Inspection Scope (92050)
The Bellefonte Nuclear Plant equipment remains in an indeterminate status. The inspectors accompanied the licensee in the walked down of the Component Cooling Water (KC) system, to confirm the system information/data identified on the Master Equipment List was accurate. This walk down also documented basic material condition, captured equipment nameplate data, and confirmed the accuracy of existing plant drawings. The inspectors verified the final walkdown QA records accurately reflected as found material condition. The inspectors also confirmed the licensee did not evaluate the condition or suitability of the as-found components nor did they take any actions that advanced construction.
b. Observations and Findings The portions of the Component Cooling Water system walkdowns were conducted in accordance with approved procedures and the results were appropriately documented.
No findings of significance were identified.
2.0 Subsurface Geology a. Inspection Scope (45051/45053)
The purpose of these subsurface investigations is to review the Quality Assurance associated with the licensing application Bellefonte unit 1. NRC inspectors visited the Bellefonte Unit 1 site to observe in-process subsurface geotechnical and geophysical investigations performed in the proximity of safety related structures. The inspectors evaluated the storage conditions to ensure the samples are kept in accordance with Regulatory Guide 1.132, Site Investigations for Foundations of Nuclear Power Plants, Revision 2, 2003.
The inspectors observed drilling and coring activities performed on boring B-106 in accordance with ASTM D 4543, 2008, using HQ triple core barrel wireline tubes, at an approximate 145 ft depth. In addition, the inspectors observed how the sample was recovered and removed from the inner barrel and how the rig geologists generated logging records to record boring location, sample name, depth interval length, rock classification, and rock quality designation (RQD). The RQD for this specific sample was 100%.
Geophysical testing activities were also observed on boring B-104. Activities were being conducted by Geovision staff, who acquired P-S velocity data for the upper 25 ft. of soil boring. In addition, acoustic televiewer, 3-arm caliper, and resistivity testing were also performed on this borehole. NRC inspectors reviewed the complete acoustic televiewer log for boring B-104 looking for possible fractures, bedding planes, and orientation of
these features. Additionally, the inspectors reviewed the training and qualification records of each member of the Geovision staff.
The inspectors reviewed the storage conditions for the rock core samples to ensure the samples were protected, labeled, and the climatic conditions had the proper humidity and temperature parameters. The inspectors observed shallow rock cores from borings B-103 (EL. 25 ft, approximate foundation level) and cores from B-104 extracted from depths of 240 ft and 365 ft; the cores from boring B-104 exhibited a low shear wave velocity (Vs) of approximate 6000 ft/s. Overall, the majority of the observed samples exhibited excellent RQD and recovery at or near 100%. To assess uniformity and consistency of Vs measurements throughout the site, the inspectors asked the licensee for the following documents:
- Preliminary Vs data from P-S suspension logging performed at boring B-104
- P-S suspension logging measurements from Units 3 and 4
- Down-hole and cross-hole Vs measurements performed for the Units 1 and 2 foundation area The inspectors reviewed these documents and compared data between the surveys. The plots showed a good correlation and consistency of Vs with depth throughout the site.
The inspectors selected random core samples and confirmed that the licensee could retrieve the sample. The inspectors confirmed the QA records associated with each of the selected samples were correct. These records included verification Hammer Calibration, Geologist Qualification, M&TE records, Complete Field Notes, core sample identification markings and storage location.
b. Observations and Findings The portions of the subsurface investigations reviewed were conducted in accordance with approved procedures, met applicable QA requirements and the results were appropriately documented.
No findings of significance were identified 3.0 Corrective Action Program (CAP)
a. Inspection Scope (92050)
The inspectors also reviewed the findings and recommendations from an internal audit in the subsurface geology area, and independently confirmed the results. The inspectors confirmed that all findings from the audit were appropriately entered into the corrective action program.
b. Observations and Findings No findings of significance were identified.
4.0 Exit Meeting Summary The inspector presented the inspection results to Mr. R. Hruby, General Manager, Bellefonte Nuclear Plant, and other members of management on December 1, 2011.
Some proprietary information was reviewed during this inspection. All material was returned to the applicant.
