SU3 JECT:
NOTICE OF VIOLATION AND FR0 POSED IMP 0c,ITION OF CIVIL PENALTY
(NRC INSPECTION REPORT NO. 50-395/86-12)
This refers to the Nuclear Regulatory Commission (NRC) inspection conducted at
the V. C. Summer facility on June 1 - July 3, 1986. -The inspection included a
review of the circumstances surrounding the misalignment of the charging pumps
which was promptly identified by the licensee and reported to the NRC.
As a
result of this inspection,-significant failures to comply with NRC requirements
were identified, and accordingly, the violations were discussed with you, members
of your staff, Mr. L. Reyes, and other members of the NRC staff in an Enforcement
Conference held on July 3,1986, at the Region II Office.
The two violations described in the enclosed Notice of Violation and Proposed
Imposition of Civil Penalty (Notice) involve the failure to maintain the charging
pumps in an operable status under certain design basis conditions from June 6-11,
~1986.
Violation I in the enclosed Notice is considered significant because none
of the three charging pumps would have automatically started for approximately
13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> on June 10, 1986 under the conditions of a loss of offsite power
followed by a safety injection signal.
Specifically, because the A diesel
generator was removed from service for maintenance, the A charging pump was
inoperable under the conditions of a loss of offsite power as it was aligned
to the A electrical train.
Because of the status of the B and C charging pumps,
one train of the charging' system was already rendered inoperable for approximately
110 hours0.00127 days <br />0.0306 hours <br />1.818783e-4 weeks <br />4.1855e-5 months <br />'from June 6-11, 1986 as' described in Violation II.
The B charging
pump would not have automatically started because its control switch was in the
pull-to-lock position. The C charging pump was prevented from automatically
starting because of electrical interlocks for a loss of offsite power followed
by a subsequent safety-injection signal.
It is apparent that system operating procedures did not properly specify the
electrical alignment of the charging pumps.
It is also apparent that training
was not adequate for the operators to fully understand the design and operating
configuration of the system. The NRC is concerned because of this and other
recent escalated enforcement actions involving the operation of your facility
and the low rating in the area of plant operations given in the latest Systematic
Assessment of Licensee Performance (SALP). While the NRC recognizes that you

identified and reported these violations, more attention to detail in system
operation and design reviews is required to ensure similar types of violations do
not recur. Weaknesses in the training area must be fully addressed in your cor-
rective actions in order to achieve improvement in the plant operations area.
To emphasize the importance of ensuring that your plant staff understands the
design and proper operating configuration of systems, the need for complete
procedures, and the need for training with appropriate operating guidance and
instructions, I have been authorized, after consultation with the Director,
Office of Inspection and Enforcement, to issue the enclosed Notice of Violation
and Proposed Imposition of Civil Penalty in the amount of Fifty Thousand Dollars
($50,000) for the violations described in the enclosed Notice.
In accordance
with the " General Statement of Policy and Procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C (1986) (Enforcement Policy), the violations described
in the enclosed Notice have been categorized as a Severity Level III problem.
The base value of a civil penalty for a Severity Level III problem is $50,000.
Mitination.of the civil penalty was considered for your prompt identification
and reporting, and your aggressiveness in taking prompt and extensive corrective
actions.
However, because this event is similar to the component cooling water
and service water system event of January 30, 1986, which also involved a proposed
civil penalty, bases for escalation of the civil penalty also exist.
Therefore,
no adjustment of the base civil penalty has been deemed appropriate.
You are required to respond to this letter and should follow the instructions
specified in the enclosed Notice when preparing your response.
In your response,
you should document the specific actions taken and any additional actions you
plan to prevent recurrence.
After reviewing your response to this Notice,
including your proposed corrective actions, the NRC will determine whether
further NRC enforcement action is necessary to ensure compliance with NRC
regulatory requirements.
In accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2,
Title 10, Code of Federal Regulations, a copy of this letter and its enclosures
will be placed in the NRC Public Document Room.
The responses directed by this letter and its enclosures are not subject to the
clearance procedures of the Office of Manager.ent and Budget as required by the
Paperwork Reduction Act of 1980, PL 96-511.
Should you have any questions concerning this letter, please contact us.
Sincerely,
