SUBJECT:

ANNUAL ASSESSMENT LETTER - OCONEE NUCLEAR STATION

(NRC INSPECTION REPORT 05000269/2005001, 05000270/2005001,

AND 05000287/2005001)

Dear Mr. Jones:

On February 8, 2005, the NRC staff completed its end-of-cycle plant performance assessment

of the Oconee Nuclear Station. The end-of-cycle review for Oconee involved the participation

of all technical divisions in evaluating performance indicators for the most recent quarter and

inspection results for the period from January 1 through December 31, 2004. The purpose of

this letter is to inform you of our assessment of your safety performance during this period and

our plans for future inspections at your facility. This will allow you an opportunity to prepare for

these inspections and to inform us of any planned inspections that may conflict with your plant

activities. The following performance review and the enclosed inspection plan do not include

physical protection information. A separate end-of-cycle performance review letter, designated

and marked as "Exempt from Public Disclosure in accordance with 10 CFR 2.390, will include

the physical protection review and a resultant inspection plan.

During the assessment period, Oconee Units 1, 2, and 3 operated in a manner that preserved

public health and safety and met all cornerstone objectives with moderate degradation in safety

performance. This moderate degradation was reflective of third quarter plant performance

within the Degraded Cornerstone Column of the NRCs Action Matrix, which resulted from two

Mitigating Systems cornerstone findings of low to moderate safety significance (White). The

first of these, which was also the reason fourth quarter performance was within the Regulatory

Response Column, was a third quarter 2004 White finding involving a failure to maintain the

licensing basis commitment for staffing the standby shutdown facility (SSF) in the event of a

confirmed plant fire. The other was a third quarter 2003 White finding involving inadequate

corrective actions to address pressurizer ambient heat losses that exceeded the capacity of the

pressurizer heaters powered from the SSF. This White SSF pressurizer heater finding also

caused plant performance during the first and second quarters of the assessment period to be

within the Regulatory Response Column of the NRCs Action Matrix.

In response to the Degraded Cornerstone performance in the third quarter of the assessment

period, a supplemental inspection will be performed under Inspection Procedure 95002. We

plan to perform this 95002 supplemental inspection in the May 2005 time frame. The

satisfactory completion of this 95002 supplemental inspection is highly dependent on your

DEC

staffs efforts to assure adequate root cause/extent of condition reviews have been performed.

It should be noted that during the assessment period, Oconee Nuclear Station received a

Severity Level III violation (with a $60,000 civil penalty) for the failure to obtain NRC approval

prior to making a change to the facility which involved unreviewed safety questions. The

corrective actions for this Severity Level III violation, which was associated with the high energy

line break analysis, will be reviewed during a future baseline inspection. Our end-of-cycle

performance assessment also included an assessment of issues that are still under staff review

to determine their safety significance. Although we recognize that you have assessed any

operability concerns associated with the following issues, the results of our Significance

Determination Process may warrant additional supplemental inspection for issues that are of

greater than very low risk significance.

Unresolved Item (URI) 050000269/2004003-01 (Inadequate Unit 1 Reactor Coolant

Pump Seal Modification)

URI 05000269,270,287/2004002-04 (Potential Failure to Maintain RB Coatings per GL 98-04 Commitments, Resulting in Potential Loss of RBES Recirculation)

URI 05000287/2004003-02 and URI 05000287/2002007-02 (Unit 3 Control Room Wall

not Tornado Protected)

In addition, the staff is also continuing its review of licensing basis issues associated with

tornado mitigation and high energy line break analysis.

The enclosed inspection plan details the inspections (less those related to physical protection)

scheduled through September 30, 2006. In addition to baseline inspection activities and the

95002 Supplemental Inspection discussed above, the plan currently includes: (1) operator

licensing examinations; (2) routine inspections of activities associated with your Independent

Spent Fuel Storage Installation; and (3) safety issue inspections concerning pressurizer

penetration nozzles and steam space piping connections (NRC Bulletin 2004-01). The

inspection plan is provided to minimize the resource impact on your staff and to allow for

scheduling conflicts and personnel availability to be resolved in advance of the inspectors

arrival onsite. Routine resident inspections are not listed due to their ongoing and continuous

nature. The inspections in the last nine months of the inspection plan are tentative and may be

revised at the mid-cycle review meeting.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter and its

enclosure will be made available electronically for public inspection in the NRC Public

Document Room or from the Publicly Available Records (PARS) component of NRC's

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).
