Reply to Notice of Violations 50-482/9708-01, -02, -03, and -05 violation 50-482/9708-01 (EA 97-108):

" Technical Specification 6. states, in part, that procedures be established, implemented, and maintained covering the activities reference in Regulatory Guide 1.33, Revision 2, February 197 Appendix A Section 7 (a), requires procedures for the liquid radioacti.ve waste syste Systems Procedure SYS HB-135, " Liquid Radwaste Demin Floor Drain and Waste Holdup Tanks Processing," Revision 0, Precaution Step 4.12, states, "Do not exceed Water Monitor Tanks A or B (THB07A or THB07B) level of 90 percent to prevent an inadvertent overflow."

Alarm Response Prccedure ALR 702, " Liquid Process Control Panel HB-115,"

Revision 2, Attachment S, "702-08A, Waste Monitor Tank 1 HI-LO Level,"

requires that liquid transfers to Waste Monitor Tank 1 (WMT B) be stopped if the level is greater than 90 percen Contrary to the above, on February 27, 1996, radwaste operators did not follow the above procedural guidance and disregarded the panel alarm when they were instructed by their supervisor to exceed the precautionary 90 percent fill limit and fill the waste monitor tank to the 95- percent leve )

!

This is a Severity Level IV violation (Supplement IV) (482/9708-01) (EA j

- 97-108). t Admission of Violation:

h

  • ')

Wolf Creek acknowledges that a violation of Technical Specification 6. ,

occurred when procedures were not followe j Reason for Violation:

On February 27, 1996, instructions to fill the Waste Monitor Tank (WMT) to greater than 90 percent capacity were given by the Radwaste Supervisor to the day shift radwaste operator and then transferred to the night shift radwaste l operato The supervisor was focused on maximizing storage capability by i

'

conserving radwaste hold-up volume due to the inability to discharge effluents at the tim Procedure SYS HB-135, " Liquid Radwaste Demin Floor Drain a id Waste j Holdup Tanks Processing," was open and in use during the processing evolution '

and contained a precaution step to limit the level to 90 percent ful This precaution was not followed by the operator The operators did not use alarm response procedure, ALR 702, " Liquid Process l Control Panel HB-115," because they knew the Radwaste Supervisor's instructions ,

would cause an alarm and they were expecting i They believed that they did i not need the ALR to troubleshoot as this was an expected alar The operators did not question that the Radwaste Supervisor's direction was contrary to procedure The Radwaste Supervisor failed to follow administrative requirements for use and adherence to procedure Additionally, the Radwaste Supervisor did not make changes to procedures when required and continued to give instructions that were contrary to procedures.

Corrective Stops Taken and Results Achieved:

The Radwaste Supervisor received appropriate disciplinary actions in accordance with WCNOC' polic To increase oversight and provide full-time supervision, the Radwaste and Water Treatment operators have been integrated into the Operating Crew On January 14, 1997, the radwaste and water treatment operators were coached and counseled about:

o the importance of maintaining a questioning attitude and their right to :

call for a " time out" e

not placing themselves in a posture of blind compliance to procedures or supervisory authority

  • reviewing procedures when making decisions to ensure that decisions are compatible with requirement WCNOC Senior Management held a site-wide stand-down meeting on February 28, l 1997, to ensure that all WCNOC personnel understand their expectations for i literal compliance with procedure Date When Full Compliance Will Be Achieved:

All of the above listed corrective actions are complete and full compliance has been achieve ,

Violation 50-482/9708-03:

" With one required diesel generator inoperable, Technical Specification 3.8.1.1, Action b, requires the performance of surveillance testing to demonstrate the operability of offsite alternating current sources by performing Technical Specification Surveillance 4.8.1.1 within 1 hou Contrary to the above, on May 16, 1996, maintenance personnel inadvertently rendered Emergency Diesel Generator A inoperable, and the licensee f ailed to perform Technical Specification Surveillance 4.8.1. within 1 hou This is a Severity Level IV violation (Supplement 1)(482/9708-03)."

Admission of ViolatioE

' Wolf Creek acknowlOdges that a violation of Technical Specification (TS) ,

occurred when Technical Specification Surveillance 4.8.1.1.1 was not completed

,

within one hour after one diesel generator was rendered inoperable. This TS

'

violation was reported in Licensee Event Report (LER) 96-008-00. During the closure of LER 96-008-00 the Senior Resident Inspector determined that the stated corrective actions would not orevent recurrence and were inadequate and the LER closed with a cited violatio Reason for Violation:

The excerpt below from LER 96-008-00 is provided for background information.

,

On May 16, 1996, troubleshooting Work Package (WP) 112603 was initiated on the computer point for the "A" Train Essential Service Water (ESW) room temperature indicator. The Control Room reviewed and approved the work package to be worke g' At approximately 1035 on May 16, 1996, as part of WP 112603, surveillance M4 procedure STN IC-465, " Channel Calibration ESW Pump Room Temperature Control Loop," was commenced on the "A" Train ESW supply fan; this procedure lifted lead RP053AC for the fan, kaeping the fan from starting on any signals, thus causing the ESW train "A" to oe inoperable. It was not recognized that this procedure

affected the operability of the ESW fan. Technical Specification 3.7.4 should have been entered; additionally, Technical Specification surveillance 3.8. should have been performed when the ESW train was inoperable for greater than one hou The Diesel Generator Technical Specification 3.8. for the "A" Train should have been entere I

-

On May 17, 1996, the troubleshooting activities on the computer point were continued, with the lifting of lead RP053A This again made the ESW "A" supply

', fan inoperable. Coinciding with these events, an oil line broke on the Control Building Air Conditioner unit, SGKC48, which caused the "3" train Control Room

-

Emergency Ventilation System (CREVS) to be inoperable. Therefore, both "A" and

"B" trains of CREVS were inoperable for ten to fifteen minutes, contrary to Technical Specification 3. 7. 6, and Technical Specification 3.0.3 should have been entere j The LER corrective actions were stat'i as follows:

Immediate:

1. STN IC-465 was revised to include cautions that during the performance of this procedure, the supply fan will be inoperabl . The importance of clear communications with the shift aupervisor, and the importance of understanding the effects of the work they perform on equipment j operability have been emphasized during I&C group meeting I

I l Long-term:  !

1. All I&C STNs will be reviewed for potential impact to equipment operability, prior to any use. This review will be completed entirely by September 20,

.

1996.

l l 2. A checklist of questions and considerations will be generated that the shift  !

supervisor and Work Control Center should ask when a troubleshooting request, *

! or a request to perform a procedure, is received to help ensure complete -

j

' communication takes place, and to address operability question This checklist will be utilized until such time as WCNOC determines that this

,

interim measure is no longer of valu September 16, 199 The checklist will be completed by

.

.  !

Inspection Report 97-08 documented three deficiencies with the above corrective .

i action ,

j j

1) The checklist to ensure complete communication between the shift supervisor i or the work control center and the maintenance personnel did not directly  ;

[ question whether the proposed work affected the operability of safety related '

work.

l ,*

As stated in LLR 96-008-00, the checklist questions should be asked when a

troubleshooting request or a request to perform a procedure is received, to j ensure that complete communications take place, and to address operability

- question It was never intended for the checklist to prompt the Shift

.

Supervisor (SS) or Supervising Operator (SO) to ask Maintenance personne. if  ;

l they considered thc work to effect operability. At WCNOC, operability can only  ;

be determined by the S The checklist does state under the preparation section  !

to " Review equipment status and system operability including any pre-planning i checklists that apply." The checklist questions were intentionally written to I be open-ended in order to prompt further thought, discussion and investigation, j 2) LER 96-008-00 stated that the checklist would be utilized until such time as l WCNOC determined that the interim measure was no longer of value. On March  !

31, 1997, the inspector.noted that Work Control Center personnel had stopped using the checklist, although the Manager Operations believed that the checklist was still being use The checklists were made into laminated cards and distributed to Operations

,

personnel, however, no clear communication or direction concerning their usage  !

was provide Interviews with Operations personnel determined that .most [

personnel found the cards useful, however, it was not understood to be a i regulatory commitment, and was not consistently use An evaluation to ,

determine if the checklist was of value was not performed necause it was not  !

desired to discontinue its us Inconsistent checklist implementation was  :

caused by inadequate communication among the groups in'olved and lack of j management expectations regarding usc of the car i 3) The corrective actions associated with reviewing procedures for inadequacy  !

and the shop meeting discussions were not performed for the electrical or mechanical maintenance group )

i Non-Instrumentation and Controls (I&C) maintenance procedures and personnel were not included because all Electrical and Mechanical Maintenance surveillance .

procedures were thought to be performed after issuance of a clearance order I isolating the equipment being teste Further research concluded that there are l some Electrical Maintenance procedures that are performed on on-line or l energized equipmen The reason for this oversight was that the review of I procedures .was inadequate and did not uncover all applicable procedures and l organization I
