SUBJECT:
SAFETY SYSTEM DESIGN AND PERFORMANCE CAPABILITY INSPECTION
NRC INSPECTION REPORT NOS. 50-269/2002-09, 50-270/2002-09, and
50-287/2002-09
Dear Mr. McCollum:
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 Oconee facility during July - August, 2002. A team of five inspectors will perform the
inspection. The inspection team will be led by Mr. J. Lenahan, 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 capability of the high pressure injection system
and support systems, as well as other related systems, to perform the functions required to
mitigate a small break loss of coolant (LOCA) event.
During a telephone conversation on April 9, 2002, Mr. J. Lenahan of my staff, and
Mr. J. Smith of your staff, confirmed arrangements for an information gathering site visit and the
two-week onsite inspection. The schedule is as follows:
Information gathering visit: May 28 - 30, 2002
Onsite inspection: July 15 - 19 and July 29 - August 2, 2002
The purpose of the information gathering visit is to obtain information and documentation
outlined in the enclosure needed to support the inspection. Mr. W. Rogers a Region II Senior
Reactor Analyst, will accompany Mr. J. Lenahan during the information gathering visit to review
PRA data and identify risk significant components which will be examined during the inspection.
Please contact Mr. J. Lenahan 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
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. J. Lenahan at (404) 562-4625.
Sincerely,
/RA/

Note: Electronic media is preferred if readily available (i.e., on computer disc).
Site specific administrative procedures related to standard operation, abnormal
operation, and emergency operation of the high pressure injection (HPI) system,
including support systems, and other related systems during a small break loss of
coolant accident (LOCA). Other related systems include, but may not be limited to the
emergency power source (Keowee), other portions of the emergency core cooling
system (e.g. the core flooding system, low pressure injection system, and containment
building sumps), the service water system, and the instrument air system.
Design criteria (i.e., design basis documents) for the HPI system and other related
systems.
HPI system Technical Specification requirements and a list of associated surveillance
test/calibration procedures for the HPI system and related systems.
