ABSTRACT (Liett to 1400 spaces, t.o., apprestestely 15 etnple spaced typewritten Lines) (14)

On 7/14/94, Unit 2 utahty lic,= ,I Jt==cear Operstors co====<=rl the Reactor Protective System penodse logic sastra test.

While testing the fourth logic matra (AC matrix), Trip Carasit Breaker (TCB) Frve failed to open. TCB 5 had opened three timo previously on demand from other matru tests. Following several ====* to open TCB-5, it was dedared out of semce.

i The rator was thus down to repair or replace TCB-5.

j The cause of the failure of TCB 5 to trip has been identified as obstruction of motion on the trip latch lever due to a broken piece of inestating matenal. A sinall piece of broken phanale insulatang anssenal ,.,,.--- A 1/4 inch square in aime was found lodgea Seeween the trip insch lever and the access slot in the bem for the trip latch. The phanal c fragment was found to have enginated from the cutoff swach used in the breaker antipump d.-7, which is physically located duecaly above the trip istch =arkism. Upon further ==p ch it was determined that a screw used in the assembly of the caeof swiech had become loose. Th> screw holds the switch to the m~~'ag block and if loose will allow the two halves of the awnch to separate when the beaker is operated. This most likely led to Switch :-P and breakage of the phenohe block.

Conective Actioos le 'ude: 1) Electncel Maintenance (EM), PPL ST 4 and a GE repr=== ear ve i==p==l he t remaming l Unit 2 TCBs and the W1 Set Output Breakers with satisfactory resuhs. 2) EM will inspect Unit 1 TCBs dunas the men l

' daled quarterly mainance and the MG Set Output Breakers dunng the next scheduled penodic rnaintenaar- 3) EM has '

.porated the inspectson of the cutoff switch phenohc block and screw into Unit 1 at 2 penodic maintenance procedures.

The utility le.a-d Senior Reactor Operator attempted to open TCB 5 locally with the local pushbutton, the emerge j

r" and by pulhas the breaker fuses. All attempts were unsuccesful. The Reactor Trip pa=kke ran for channel MA TCBs 1 and 5 was depressed without success. At 0330 TCB-5 was declared out of servux. TCBs 1,2 and 6 were opened 0418, which opened the series breaker and the parallel supply path to the Contml Element Drive M-ekaa:*- bus (EII the 'A' side. .

At 0740 a reactor shut down was co==>-r d in order to repair or replace TCB 5. The TCBs and the CEA Bus Motor Generator (MG) Set Output Breakers (EDC:ED) are General Electric (GE) Type AK 2 25. TCB-5 was replaced and the 1 sning Unit 2 TCBs and MG Set Output Brunkers were inspected ='-ba-ily. Unit 2 was then restored to 100% ste

, power operations.

s CAUSE OF THE EVENT i

I The cause of the failure of TCB.5 to trip has been identified as obstrucuon of motion on the trip latch lever. A small p broken phenolic insulating material approwimar.ly 1/4 inch square in size was found lodged between the trip latch lever the access slot in the base for the trip lates . When the breaker was called upon to trip, electrically or manually, the piece restricted the motion of the trip latch lever such that the breaker enachnaiam would not operate. Upon the remov i phenolic fragment, the breaker i===&=' y tripped open and was s' .

3 close operations. tly found to operate freely during manual open and l i

! l The phenohc fragment was found to have crismated from the cutoff switch (See Figure Two) used 1 in the breake i

circuitry, which is physicaDy located directly above the brunker trip latch mark =ai== The cutoff switch operates  :--11 7 -h-each time the bronker is opened or cloesd.

Upon further inspection, it was determined that a screw used in the ausmbly of the cutoff swnch had become loose. This screw holds the swach to the mounting block and if loose will suow the two halves of the swach to separate when the bre

is opwated. This most likely led to swnch '"7 ~ and brunkage of the pbsenlic block.

' The potential root causes of the loose screw and phenolic material breakage are either a manufacturmg defect or inadverten damage dunas maint ===c-A esarch of industry maintenance records did not indicate any smular type failures and has been determined by FPl. F=f 4 and GE to be a first time event.

ANALYEM OF THE EVENT: li This event is not reportable under 10CFR50.73; however, it is being submitted voluntarily for industry infor'==*iaaal purposes.

The St. Lucie Unit 2 T-rhale=1 '.,, ;hdons Se.: tion 3/4J.1 ' Reactor Protective Instr =-e=Iaa' requires a minimum of four operable ek - I for continued operation in anodes 1 and 2. Each Reactor Trip Breaker channel is comprised of two TCBs and a comanon actuation trip logic path, for a total of four eka== ale. (See Figure One) The Action - ==-ar ==arine-4 with  !

this specification is that with the number of ch====le OPERABLE one less than required by the Minimum chanaal.

OPERABLE requirement, STARTUP and or POWER OPERATION may continue pewided the TCBs of the inoperable chaaniel are placed in the snpped condition within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, otherwne, be in at least HOT CTANDBY wnhin 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. The ,

BASES for this specil; cation is to ensure that for the RPS instru==ae-iaa and bypasses: 1) the -e-I reactor trip will be  !

initiated when a parameter monnored by och channel or mmbination reaches its serpoint,2) the y r E 3 co:--u---- logic is

-.:.,..:.i-8 i

3) sufficient i ' b-7 s ni=Iar=== i to permit a chaan,1to be out d service for tening or main .a==e- ad i
4) sufficient system functional capability is available from diverse parameters. l To comply with the intent of the TCB action ====aat operators opened TCB4, the breaker in series with TCIk5, and TCB-1.

ensured that these RPS trip paths were placed in the fail safe condition, and that the safety fnarriaa for these trip paths carried out. Therefore the following was guaranteed: 1) the instaanon of a reactor trip on a valid condition,2) RPS actuadon logic of 1/2 ek-- l . 3) equipment i--' - 'y while TCIL5 was repaired,4) all diverse RPS measurement ek --l-were available and 5) 3-- 3:-- access for root cause analysis and repair of TCB-5. As an additional measure, TCB-2 was ,

P#8d- .

i The Updated Final Safety Analysis Report (UFSAR), Section 7.2 and Failure Analysis Table 7.2 5, analyzes the c :a- ,

described in this report, a Trip Circuit Breaker failing closed. c; r;Ce=11,ythe RPS is designed so that any single failure within the system does not prevent proper protectrve action at the system level. The wiring in the system is grouped so that no single l fault er failure, including either an open or shorted circuit, negates the protective systeen operation. The UPSAR states that if one ef two series redundant TCBs in one of two parallel redundant paths to supply power to the CEAs will not open on a trip signal due to mark- :- I binding, the inherent compenseung powision is that the series rednadaar breaker can interrupt I power on the affected trip path, and the RPS trip logic is na= Hare-I The method of A=earrian for this fault is the monthly l RPS Logic Matrix test. )

i Therefore, the health and safety of the public were not affected during this event.

'- Attachment 2 consists of.a draft letter to the licensee and a Notice of-Violation. Attachment 3 contains the reference material appropriate to~this 4

ca' se.

Three violations were identified for (1) the failure to meet Technical Specification requirements to maintain the-Pressure Operated Relief Valves (PORVs) operable when at low pressure conditions; (2) the failure to adequately identify and perform post-maintenance' testing of the PORVs; and (3) the failure i to perform adequate inservice testing of the PORVs. We propose that the issue be classified as a Severity Level III problem consistent with Supplement I.C.2.a of the Enforcement Policy: A system designed to prevent or mitigate a serious safety event not being able to perform its intended function under certain L

conditions. Application of the civil penalty assessment process would have '

resulted in a fully mitigated civil penalty but due to the poor licensee performance in this case, discretion was applied to impose the base civil penalty.
