Notice of Violation 2 OCT 2 91987

8. 10 CFR Part 50, Appendix B, Criterion XVI_. requires in part that the identification of a significant condition adverse to quality, the cause of the condition and the corrective action taken be reported to the appropriate levels of management.

10 CFR 50.72 requires the licensee to notify the NRC Operations Center via the Emergency Notification System of events described in Paragraph (b) of this section. Paragraph (b)(2), states, "Four hour reports.

If not reported under Paragraph (a) or (b)(1) of this section, the ,

licensee shall notify the NRC as soon as practical and in.all cases, within four hours of the occurrence. of any of the following...(iii).

Any event or condition that alone could have prevented the fulfillment of the safety function of structures or systems that are needed to...

(D) Mitigate the consequences of an accident."

Contrary to the above, on August 18, 1987, at 3:30 a.m. the plant staff identified that the main steam isolation valves would not have been able to perform their intended function but this condition was not promptly evaluated or reported to the appropriate levels of licensee management.

l Additionally, it was not reported to the NRC Operations Center via the Emergency Notification System until 12:00 noon on August 20, 1987. This represented a period of 56 hours6.481481e-4 days <br />0.0156 hours <br />9.259259e-5 weeks <br />2.1308e-5 months <br /> and 30. minutes after _ discovery.

2. Introduction 4 During day shift on August 17, 1987, when it became evident thatt the inspection of the 2X01 transformer was going to take: longer...than~  ;

anticipated and with the requirement.to repair the steam driven auxiliary

~

feedpump prior to unit criticality, maintenance personnel decided'they had enough time to perform some: minor secondary sidelinspections/ repairs and requested that operations personnel tag the main steam: isolation

. valves (MSIVs) shut to facilitate this work. . TheJoperations supervisor-was quite busy at the time and requested.that the. Unit 12 reactor operator-fill out the danger tag location sheet and the red ta'gs. !When the reactor-operator finished, he1provided the'sheetito the! operations supervisor for.

review. The operations supervisor noted that the tagout.providedLfor four- ~

tags tagging the-two DC control power breakers to the instrument air'-

solenoid valves ~open and the'two instrument' air isolation valves to the MSIVs' shut. He concluded that tagging th'e instrument' air: isolation 4 i

(stop) valves shut would prevent opening the MSIVs and tagging the DC' .

control power breakers open would prevent the solenoid valves 1 from being continually energized with the control room switch in the closed position, a normal' practice during long term outages. 'He then turned-the. tags over-to two qualified red. taggers to perform the tag outJand verification. j Once_the tags were hung, one copy of the' danger tag location' sheet wasi kept in the control room and the other was given to maintenance ~ personnel-as approval to start work; i

At about 9:00 p.m. on Augustc17, 1987, the maintenance foreman notified the control room that the' secondary side work.was completed and the-tag; out on the MSIVs could'be removed.; The swing shift operations supervisor removed the tag.out. sheet from the' log book and assumed.from.the wording-that.the two instrument: air ~stop valves were tagged shut and that.two of,. J '

theLlocal vent solenoid valves were tagged open. 'Because it was.

approaching shift. turnover time, he. called the auxiliary building" aux'iliary.

operator (AO) an'd told him to " remove the-red tags on the MSIVs'and open the = instrument air stop valves." The AO completed this task'and called back to the control. room reporting,."the red tags;have been removed and the instrument air stops are open." Again.'using his initial assumption, the operations supervisor assumed that all four? red tags had been removed _

and he initialed the cleared section of!the danger tag-locationLsheet with-a slash and the' A0's initials to indicate that the tags were cleared per-verbal verification. In fact, only two of the four red tags had been.

removed.

At 11:0S p.m., August 17, 1987, the mid-shift shift supervisorLordered his auxiliary building A0 fto reset the four instrument. air solenoid valves-for each MSIV, thereby opening the MSIVs. .At 3:30 a.m., August- 18. 1987, ,

- during performance of OP-10, " Low. Power Operation to Nomal) Power Operation,".

Step 4.1, " Energize Following Circuits," the shift supervisor went to the-DC control power breaker panels. _He opened the door on thetfirst panel-to.look for the circuits by name and noticed the red tag on:the "A".MSIV -

solenoid power' supply. - He checked further in another panel. and found. the "B" MSIV solenoid power supply.was also tagged open. He then checked and-found that the tag series had been cleared.on the previous shift and knew ^

that there was no secondary maintenance.in' progress so he; removed the red tags and closed the breakers. He then went on with the' normal business-of lighting off the turbine and getting the unit on line.

When the mid-shift shift supervisor Ltook the watch:the { initial conditions of OP-10 had been' signed off as completed although after Step 3.1 was completed the MSIVs were tagged. shut for maintenance { Stepl3.1 required the performance of applicable portions of OP-13A. The shift supervisor started'reaccomplishing the . steps in OP-13A, " Secondary Systems Startup and Shutdown," Section 4.5, " Bringing-Steam Into Turbine _ Building."

When he got to Step 4.5.4, "Open and Cycle the MSIVs," he made~ the decision that inasmuch as'they had already.been cycled and IT-280/285,." Inservice Testing of Main Steam Stop Valves," had been run earlier that day there was no need to cycle the MSIVs again. Had he.not. violated procedural step 4.5.4 the subsequent investigation as to why the MSIVs.would not shut would have disclosed the' open breakers.

The mid-shift shift supervisor left a note for the swing shift operations supervisor stating'that he had found the MSIV solenoid'breakersLtagged open and that a violation may have been involved. The swing shift' operations supervisor and shift supervisor prepared a nonconfonnance report detailing.the incident.. This -information did not reach the appropriate individuals until'the next day at which. point they decided that they.had a Technical Specification violation and an LER would be-required.- However, they wanted more information from the. shift supervisor-before making a determination on the emergency notification system.(red '

phone) deportability to the NRC. - Therefore, red phone notification was: 1 delayed until noon on August 20, 1987.-

l 4. Document Review l 1 The inspector reviewed the following documents:

  • Nonconformance Report No. N-87-140 Unit 2 Main Steam Stop Valves-
  • Technical Specification 15.3.5 Instrumentation System- 4
  • FSAR 14.2.5 Rupture of a Steam Pipe
  • OP-1C " Low Power Operation to- Normal! Operation" .]
  • OP-13A " Secondary System Startup and Shutdown"'
  • PBNP 4.2.1 " Shift Superintendent"  ;

q

  • PBNP 4.12.1 " Guidelines for Watch Standing" ,j
  • PBNP 4.13 " Equipment Isolation Procedure (Danger Tag Location)"
  • Point Beach Nucisar Plant Danger Tag Location Sheet
  • Incident Investigation 87-04 Preliminary Report  !
5. Cause The failure to properly clear the red tags appears to.be an isolated case- l of poor communications. Contributing factors, althoughinot, procedural.  ;

violations, were:  !

1. Danger tag location sheet not specific enough as to tag. location.

l ,1 j

5 l

~ . -

i

2. Failure to specify how many tags were to be removed.

3.- Decision that cycling MSIVs was not'necessary.

4. Failure to notify upper management immediately of possible i violation for deportability determination.

I Therefore, the cause appears to be twofold: an equipment isolation 1 procedure which is not specific enough; and a prevailing attitude _in the operations group that the MSIVs are not as.significant to safety as other safety-related equipment.

6. Technical Specification and Code Applicability Technical Specification 15.3.5.C requires a minimum number of operable channels for each of the four methods of steam line isolation. If these 'l minimum operability requirements cannot be met,-the unit must be in hot shutdown. With no DC control power, none of the minimum operability requirements were met for the four hours and 35 minutes that the MSIVs were~ open and the reactor was critical at low power.

10 CFR 50.72 (b)(2)(iii)(D), requires that any event or condition that alone could have prevented the fulfillment of the safety function of structures or systems that are needed to: mitigate the consequences of an accident, shall be reported as soon as practical, and in all cases within four hours of the occurrence. This event was-not reported until 79 hours9.143519e-4 days <br />0.0219 hours <br />1.306217e-4 weeks <br />3.00595e-5 months <br /> and 30 minutes after. initial discovery.- i

7. Exit Interview-The inspectors met with licensee representatives (denoted'in-Parag.aph 1)  !

, throughout the inspection period and at the conclusion of the inspection period to summarize the scope and findings of the inspection activities.

The licensee acknowledged the inspectors' comments. The inspectors also discussed the likely informational content of the inspection report with regard to documents or processes reviewed by the inspectors during the inspection. The licensee did not identify any such documents / processes as proprietary.
