During an NRC inspection conducted from October 8 through November 24,1997, three
- violations of NRC requirements were identified in accordance with the " General Statement of-
!
Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed
below-
1.
Technical Safety Require nent 3.9.1 requires, in part, that written procedures be prepared
4
and implemented to cover the activities described in Safety Anahsis Repor1 (SAR)
'
,
'
- -
Sechon 6.11.4.1 and listed in Appendix A to SAR Section 6.11.
Appendix A to SAR Section 6.11 identifies " investigations and reporting" as an activity
requiring an administrative procedure.
,
Step 6.1.2 of Procedure UE2-RA-RE1030, " NUCLEAR REGULATORY EVENT -
REPORTING," Revision 2, dated February 28,1997, requires that the plant shift
o
superintendent (PSS) review problens reports and determine reportability of the event or
i
condition using Appendix D. Step 6.2.1E of the procedure requires that the PSS verbally
l
notify the appropriate NRC office within the time requirements shown in Appendix D.
.
Appendix D,"NRC REPORTING CRITERIA," of Procedure UE2-RA-RE1030, specifes
. the criteria and reporting time for events and conditions. Specifically, the following criteria
'
.
and reporting times are identified:
,
Criterion J.1.s requires, in part, a 24-hour report for an event in which equipment is
disabled or fails to function when it is required by Technical Safety Requirement
(TSR) to mitigate the consequences of an accident; is required by TSR to be
available ano operable and either should have been operating or should have
operated on demand; and no redundant equipment is available and operable to
.
perform the required safety function.
Criterion A.2.c requires, in part, a four-hour report for operations that comply with
the double contingency principle in which moderation is used as the primary
criticality control and where it is determined that a crit;cality safety analysis was
,
deficient and the necessary controlled parameters were not established or
-
maintained.
Criterion L.4 requires, in part, an immediate report (within one hour) for any
infractions, losses, compromises, or possible compromise of classified information
or c;assified documents.
h
Contrary to the above, investigation and reporting activities were not performed in
i
accordance with the written procedure, Specifically, the certificatee failed to determine
- y
.the reportability of the event and notify the appropriate NRC office within the time L
.
.
requirement shown in Appendix D in the following examples-

A.
On October 17,1997, an event occurred causing a loss of power (tripped breaker)
,
for the Building C-310 high-voltage process gas leak detection system alarms -
required by TSR 2.3.4.4 to be operable and available to mitigate the consequences
i
- of an accident (release) and for which there was no redundant equipment. The -
certificate did not report the event until October 20,1997, a period exceeding the
'
24-hour reporting requirement of Cdterion J.1.a.

On October 18,1997, an event occurred causing a loss of power (tripped breaker):
for the Building C 310 high-voltage process gas leak detection system alarms
required by TSR 2.3.4,4 to be operable and evalfable to mitigate the consequences
of an accident (release) and for which there was no rotundant equipment. The
,
certificate did not report the event until October 21,1997, a period exceeding the .
,
24-hour reporting requirement of Criterion J.1.a

B.
On November 10,1997, the certificatee discovered that the criticality safety
',
analysis for the Freon and uranium hexafluoride separation system, an operation
'
l
(hat complies with the double contingency principle and in which moderation is
used as the primary criticality control, was deficient in that it did not establish the
'
controlled parameters for the holding drums associated with the system. The
i
,
certificateo did not report the condition until November 19,1997, a period
exceeding the four-hour reporting requirement of Criterion A.2.c.
'
- C.
On November 18,1997, at approximately 5:15 p.m., the certificateo discovered an
infraction of classified information controls in that a classified document was
improperty_ shredded in an unapproved device. The certificatee did not repost the
infraction until approximately six hours later, a period exceeding the one-hour
reporting requirement of Criterion L.4.
l
This is a Severity Level IV violation (Supplement VI). (VIO 70-7001/97011-01a,b,c)
i
2.
Technical Safety Requirement 3.10.5 requires, in part, that the Plant Operations Review
Committee be used to conduct reviews of all nuclear criticality safety evaluations and
'
approvals.
!
Contrary to the above, as of November 7,1997, the Plant Operations Review Committee
-
l
was not used to conduct a review of a change causing a decrease in the approved -
margin of safety documented in the nuclear criticality safety evaluations for use of fissile
- waste drums, due to approval of drum wall thicknesses less than the minimum value .
previously assumed by the nuclear criticality safety staff. (VIO 70 7001/9701106)
-
3.
- Technical Safety Requirement 3.11.2, requires, in part, that all operations involving
I
uranium enriched to 1.0 weight percent or higher and 15 grams or more of uranium-235
'
be based upon a documented nuclear criticality safety evaluation and performed in
accordance with a documented nuclear critic.ality safety approval.
Contrary to the above, from March 3 through November 19,1997, operation of the -
Building C 335 Freon and uranium hexaflouride system holding drums in a standby mode,
- while containing Freon and uranium hexafluoride enriched to greater than one weight
