Sr. Vice President and

Chief Nuclear Officer

SUBJECT: SURRY NUCLEAR POWER STATION - NRC INSPECTION REPORT

50-280/02-07, 50-281/02-07

Dear Mr. Christian:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

Region II staff will conduct a Safety System Design and Performance Capability inspection at

your Surry Nuclear Power Station during June 2002. A team of four inspectors will perform the

inspection. The inspection team will be led by Mr. Frank Jape, a senior reactor inspector from

the NRC Region II Office. The inspection will be conducted in accordance with baseline

Inspection Procedure 71111.21, Safety System Design and Performance Capability.

The inspection objective will be to evaluate the ability of the plant and operators to respond to a

steam generator tube rupture. The inspection will focus on performance of installed equipment

that will be utilized to mitigate the event, and provide adequate core cooling.

During a telephone conversation on, March 26, 2002, Mr. Frank Jape of my staff, and

Mr. Barry Garber of your staff, confirmed arrangements for an information gathering site visit

and a two-week onsite inspection. The schedule is as follows:

  • Information gathering visit: April 23-26, 2002
  • Onsite inspection: June 10-14, 2002 and June 24-28, 2002

The purpose of the information gathering visit is to obtain information and documentation

outlined in the Enclosure needed to support the inspection. Mr. Walter Rogers, a Region II

Senior Reactor Analyst, may accompany Mr. Frank Jape during portions of the information

gathering visit to review PRA data and identify risk significant components which will be

examined during the inspection. Please contact Mr. Frank Jape prior to preparing copies of the

materials listed in the Enclosure. The inspectors will try to minimize your administrative burden

by specifically identifying only those documents required for inspection preparation.

During the information gathering visit, the team leader will also discuss the following inspection

support administrative details: office space; specific documents requested to be made available

to the team in their office space; arrangements for reactor site access; and the availability of

VEPCO 2

knowledgeable plant engineering and licensing organization personnel to serve as points of

contact during the inspection.

Thank you for your cooperation in this matter. If you have any questions regarding the

information requested or the inspection, please contact me at (404) 562-4605, or

Mr. Frank Jape at (404) 562-4541.

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).

INFORMATION REQUEST FOR THE SAFETY SYSTEM DESIGN AND

PERFORMANCE CAPABILITY INSPECTION:

STEAM GENERATOR TUBE RUPTURE EVENT

Note: Electronic media is preferred if readily available (i.e., on computer disc).

1. Design basis documents for the reactor protection system (RPS), the engineered safety

features, pressurizer relief valves, secondary system relief valves, atmospheric dump

valves and turbine bypass valves. Include performance history of these valves for the

past 10 years.

2. A list of associated surveillance tests and calibration procedures for the operational

safety instrumentation as listed in Technical Specification (TS) 3.7, Table 3,7-1 items: 5,

7, 8, 9, 11.a, 15 and 17.

3. Procedures used for the operational testing of the safety injection system check valves

410, 24, 79, 82, 85, and 25.

4. Summary of results of the steam generator inservice inspection program.

5. Mitigation strategy for handling steam generator tube rupture events (SGTR) including

E-0 and E-3.

6. List of current open temporary modifications and operator work arounds involving any

components required for mitigating a SGTR event.

7. System description and operator training modules for SGTR event.

8. List of operating experience program evaluations of industry, vendor, or NRC generic

issues related to a SGTR event.

9. Procedures that would be used to sample the reactor coolant system (RCS) during a

SGTR event.

10. Calibration and functional testing procedures for the radiation monitoring instrumentation

used during a SGTR event.

11. Calibration and functional testing procedures for the reactor trip interlocks as specified in

TS 2.3-4 B 1 and 3.
