SUBJECT: NRC INSPECTION REPORT 50-458/98-16, NOTICE OF VIOLATION, AND
EXEPCISE OF ENFORCEMENT DISCRETION
- Dear Mr. McGaha:
From July 20 to August 7,1998, an engineering and fire protection inspection was conducted at
your River Bend Station reactor facility. Additional in-office review was conducted following the
onsite portion of the inspection and an exit meeting was conducted with you via telephone on
October 15,1998. The enclosed report presents the scope and results of that inspection.
The inspection reviewed your design engineering processes associated with the high pressure
core spray, standby gas treatment, and 4.16 kV electrical distribution systems. In addition, we
reviewed your program for implementation of 10 CFR 50.59 and several items that had been
previously identified during the Fire Protection Functional Inspection (NRC Inspection
Report 50-458/97-201).
- Overall, we determined that engineering activities were generally effectively implemented, as
exemplified by calculations, modifications, and condition reports that exhibited sound
engineering practices.
Wo found that your 10 CFR 50.59 program was satisfactory, but noted one exception.
Although the results of a revised calculation of the dose consequences of a loss-of-coolant
'
accident were significantly greater than the previous results, you determined that an unreviewed
safety question did not exist. We disagreed with this conclusion and determined that it
constituted a change to the facility as described in the updated safety analysis report and that it
involved an unreviewed safety question. This constituted a violation (EA 98-425) because prior
Commission approval was required, but not obtained,
o
With respect to the unresolved items from the Fire Protection Functional Inspection, we
identified two violations. One of these violations met the criteria for consideration as a noncited
violation and involved your identification that no procedure existed for placing the standby
service water system in service to provide a seismically-qualified source of water to the fire
protection system hose stations following a safe-shutdown earthquake. You initiated action to
correct the violation.

The second violation (EA 98-460) involved the evaluation criteria and analysis methodology for
l
circuits of equipment whose spurious actuation could adversely affect post-fire safe-shutdown
l
capability. The specific condition, that you identified, involved the potential for fire-induced
circuit faults in a single multi-conductor cable that could result in the simultaneous opening of all
(16) safety relief valves and adversely affect alternative safe shutdown capability. You informed
us during public meetings on August 19,1997, and July 29,1998, and in your June 30,1998,
response to the fire protection functional inspection report that you have concluded that this
'
postulated event is not risk significant and protective measures to prevent it were beyond the
requirements of your licensing basis. However, the NRC has concluded that it is within the
licensing basis of the facility and our position is consistent with previously issued NRC guidance
for implementation of fire protection requirements. Accordingly, we have determined that this
condition constitutes a violation of your fire protection program provisions as required by
Operating License Condition 2.C.10. After consultation with the Director, Office of Enforcement
and the Regional Administrator and in accordance with Section Vll.B.6 of the NRC's
Enforcement Policy, the NRC is exercising enforcement discretion to not propose a civil penalty
and to not issue a notice of violation for this potential Severity Level Ill violation. Discretion was
warranted because of: (1) the apparent widespread misunderstanding of the requirements, (2)
the fact it was licensee identified, (3) the low risk significance, (4) the fact that you took
compensatory actions, and (5) your commitment to implement a modific.ation during the next
.
refueling outage that will correct the condition.
!
Please note that you are required to respond to this letter with respect to the cited violation of
10 CFR 50.50 and should follow the instructions specified in the enclosed Notice when
l
preparing your response. The NRC will use your response, in part, to determine whether
further enforcement action is necessary to ensure compliance with regulatory requirements.
l
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter, its
l
enclosures, and your response will be placed in the NRC Public Document Room.
Please contact me if you have any further questions about this matter.
Sincerely,
i
