SUBJECT: BRUNSWICK STEAM ELECTRIC PLANT - NRC EXAMINATION REPORT

50-325/2003-301 AND 50-324/2003-301

Dear: Keenan:

During the period February 10-13, 2003, the Nuclear Regulatory Commission (NRC)

administered operating examinations to employees of your company who had applied for

licenses to operate the Brunswick Steam Electric Plant. At the conclusion of the examination,

the examiners discussed the examination questions and preliminary findings with those

members of your staff identified in the enclosed report. The written examination was

administered by your staff on February 19, 2003.

All seven applicants passed the operating examination. There were two post examination

written comments which are discussed in Enclosure 2. A Simulation Facility Report is included

as Enclosure 3.

In accordance with 10 CFR 2.790 of the NRCs Rules of Practice, a copy of this letter and its

enclosures 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).

SUMMARY OF FINDINGS

ER 05000325/2003-301, ER 05000324/2003-301; Carolina Power and Light; on 2/10-13/2003;

Brunswick Steam Electric Plant, Units 1 and 2, Licensed Operator Examinations.

The NRC examiners conducted operator licensing initial examinations in accordance with the

guidance of Examiner Standards, NUREG-1021, Revision 8, Supplement 1. This examination

implemented the operator licensing requirements of 10 CFR §55.41, §55.43, and §55.45.

The NRC administered the operating tests during the period February 10-13, 2003. Members

of the Brunswick Steam Electric Plant training staff administered the written examination on

February 19, 2003. The written examinations were developed by the NRC. The operating tests

were developed by the Brunswick Steam Electric Plant staff from outlines developed by the

NRC. All applicants, three Reactor Operators (RO) and four Senior Reactor Operators (SRO)

passed both the operating and written examinations. All applicants were issued operator

licenses commensurate with the level of examination administered.

No significant issues were identified.

Report Details

4. OTHER ACTIVITIES (OA)

4OA5 Operator Licensing Initial Examinations

a. Inspection Scope

The examiners developed the written and operating examinations in accordance with

the guidelines specified in NUREG-1021, Revision 8, Supplement 1.

The examiners reviewed the licensees examination security measures while preparing

and administering the examinations to ensure examination security and integrity

complied with 10 CFR 55.49, Integrity of examinations and tests.

The examiners evaluated three Reactor Operator (RO) and four Senior Reactor

Operator (SRO) applicants who were being assessed under the guidelines specified in

NUREG-1021. They administered the operating tests during the period February 10-13,

2003. Members of the Brunswick Steam Electric Plant training staff administered the

written examination on February 19, 2003. The evaluations of the applicants and review

of documentation were performed to determine if the applicants, who applied for

licensees to operate the Brunswick Steam Electric Plant, met requirements specified in

10 CFR Part 55.

b. Findings

No findings of significance were identified.

The licensee submitted two post examination comments concerning the written

examination (ADAMS Accession Number ML030650592). The RO and SRO written

examinations and answer keys, combined RO/SRO examination and examination

references may be accessed in the ADAMS system (ADAMS Accession Numbers

ML030650589, ML030650584, ML030650572 and ML030650560).

4OA6 Meetings

Exit Meeting Summary

On February 14, 2003, the Chief Examiner discussed generic applicant performance

and examination development issues with members of licensee management.

The inspectors asked the licensee whether any materials examined during the

inspection should be considered proprietary. No proprietary information was identified.

NRC RESOLUTION OF FACILITY COMMENTS

RO QUESTION #36/ SRO QUESTION #25:

Facility Comment: The question asked for the expected ERFIS tail pipe temperature indication

for an SRV opened with RPV pressure at 1005 psig. The answer key indicated that "B" was the

correct answer (300 degrees). Answer "B" (300 degrees) corresponded to an isenthalpic

throttling process from 1000 psig to atmospheric pressure on the Mollier diagram. At the

Brunswick Plant, a temperature element is installed in each tail pipe just downstream of the SRV

which feeds a recorder, ERFIS, and a common control room annunciator. At the temperature

probe location, atmospheric conditions would not exist with an open SRV due to the

backpressures created from underwater discharge through a "T" quencher in the torus.

The facility recommended that the correct answer be changed to "C" (350 degrees). Per the

System Description Procedure (SD-20) which discusses temperature indications, the theoretical

temperature (indication) is 350 degrees F for steam being throttled through a leaking SRV. This

is supported by the annunciator procedure for SRV leaking (or open) which includes SRV

temperature alarm setpoints as high as 340 degrees F to indicate an open SRV.

NRC Resolution: Recommendation accepted. Review of additional reference material SD-20

page 14, indicated that 350 degrees F is the theoretical temperature for steam being throttled

through a leaking SRV. The answer key was changed to reflect C as being the correct answer.

RO QUESTION #82/ SRO QUESTION #77:

Facility Comment: The question asked for the plant impact from high radiation conditions in the

reactor building with a failure of ventilation isolation dampers to close and both Standby Gas

Treatment (SBGT) trains running. The answer key indicated that "D" (a ground level release of

radioactivity could occur) was the correct answer.

The facility recommended that "A" (an elevated release of radioactivity from the main stack could

occur) be accepted as an additional correct answer. This recommendation was based on both

SBGT trains running (discharging to the stack) with high radiation conditions in the reactor

building. Per the Brunswick Plant Updated FSAR, the SBGT (i.e., SGTS) system provides a

means for minimizing the release of radioactive material from containment to the environs by

filtering and exhausting the atmosphere from the reactor building during containment isolation

conditions. Per the UFSAR, an "elevated release is assured by exhausting to the plant stack."

With the SBGT system not 100% efficient in removal of radioactivity, with both systems in

operation under high radiation conditions in the reactor building, an elevated release from the

stack would result. Therefore, both answers "A" (an elevated release of radioactivity from the

main stack could occur) and answer "D" (a ground level release of radioactivity could occur) are

both correct.

NRC Resolution: Recommendation accepted. The expected answer, D, was based on the

assumption that a ground level release could occur if the Reactor Building Dp was zero along

with the other conditions given in the question. Implied in these conditions is that a higher level

Enclosure 3

of activity exists in the reactor building. If this were true then choice A is a true statement also,

since a higher level of activity passed through the SBGT system Could result in an elevated

release of radioactivity from the main stack. The answer key was changed to reflect A as an

additional correct answer.

SIMULATION FACILITY REPORT

Facility Licensee: Brunswick Steam Electric Plant

Facility Docket No.: 050-00325, 050-00324

Operating Tests Administered on: 02/10-13/2003

This form is to be used only to report observations. These observations do not constitute audit

or inspection findings and, without further verification and review, are not indicative of

noncompliance with 10 CFR 55.45(b). These observations do not affect NRC certification or

approval of the simulation facility other than to provide information that may be used in future

evaluations. No licensee action is required in response to these observations.

While conducting the simulator portion of the operating tests, examiners observed the following

items:

ITEM DESCRIPTION

1. Augmented Off-gas (AOG) Guard Bed Fire did not produce an increase in

radioactive release from the plant stack as would have been expected. A

fire in the guard bed would have been expected to have a substantial

increase in plant stack radiation. During this event there was no increase

in stack release.
