- . Five violations were identif;ed for which Notices of Violation are not being
. issued in accordance with the exercise of discretion delineated in 10 CFR 2, Appendix C, Section V.A.or V.G.1. *These involved a failure to adequately
control the* status.of under ves.sel platform co.vers such that a source range monitoF (SRM) was subsequently damaged during movement (paragraph*2), a
-
- failure to follow procedure involving radiation prbtection practices
- .(paragraph 4), a failµre to follow procedure regarding a main steamline plug installation such that a small portion of _the reactor cavity drained to the
-~rywell (paragraph 5.a), a failure to maintafn records for a.standby gas**
treatment system (SGTS) *written safety evaluation (paragraph*5*.b} and a fa~lure to post a proposed imposition of a ~ivil penalty (paragraph 7.c).
Six unres_o.lved items were also identified. the inspector's identification
- that the service air supply to three of the. Unit 3 drywell purge an~
ventilation fan dampers had been "disconnected is pending review of system design and the role of the operators in the event (paragraph 4.c). The failure of electrical wiring diagram 12E2697 to. reflect actual plant configuration which resulted in an unexpected ESF actuation is pending review of licensee corrective actions (paragraph 4~e). The inspector's identification of the licensee's usage of a temporary pump and hose assembly to augment filtering of the reactor cavity water during refueling without a procedure or temporary alteration is pending further review of safety implications and 10 CFR 50.59 aspects *(para9raph 4.f). Failure of a primary containment.integrated leak rate test 1IlRTJ due to a leaking torus to reacto~
building vacuum breaker is pending review of the adequacy of post-maintenance testing (paragraph 5.b). The failure to obtain a technical specification change and initiate ~orresponding surveillance calibration requirements for a modification to the generator load reject scram on turbine control fast closure is pending further review of 10 CFR 50.59 implications (paragraph 5~c). Inspector concerns regarding conformance to Generic letter 82-12 guidelines on overtime is'pending review of further plant* ~taff groups
{paragraph 7.b).
Plant Operations
.
.
A review of the Operations Department in regard to overtime policy indicated that inst~nces of exceeding Generic letter 82-12 guidelines was minima However, certain concerris were raised in that fuel-handlers, except for the fuel handling supervisors, were not included and the level of approval for exceeding the guidelines* delitieated in administrative procedures did not appear consistent with Generic L~tter 82-12 inten.
.*
The inspectors noted th~t general housekeeping and contamination control had deteriorated during the Unit 2 refueling outage as compared to recent previous refueling outages.. The licensee* planned to implement a_ new material condition/housekeeping/safety inspection program in January 1991..
.*
- I Maintenance/Surveillance Two inst~nces of failing to follow procedur~ inv6lving maintenance personel were noted. These involved maintenance practices on 10 CF~ 50 Appendix R emergency lighting batteries and main steam line plug installation. However, both actually occurred prior to licensee corrective actions to address
personnel pe~formance problems delineated in inspection report 50-237/90023; 50-249/9002.
.
.
A review of the Maintenance Department° in regard to overtime policy indicated.*
- that instances of exceeding Generic Letter 82-12 guidelines was minima Engineering/Technical Support Subsequent to the Notice of Violation and Proposed Imposition of Civil Penalty dated November 28, 1990 involving a IO CFR 50.59 violation, the inspector identified concerns which indicated additional poor past practices regarding the licensee's safety evaluation proces For example, a failure to maintain records of a written safety evaluation involving SGTS is identified as a non-cited violation *. In addition, two unresolved items needed further review wiih regard to 10 CFR 50.59 requirement These includ~d a failure to obtain a technical
- specific~tion ch~nge regarding a ~odification to the generator load reject scram function.and the use of a temporary pump and hose assembly, without a safety evaluation, for the reactor cavity water filtering syste The root causes associated with the failure to post a proposed impostion of a civil.penalty were repetitive to the cause of a previous violation involving a failure to ensure personnel were properly* trained on specific administrative requirement The licensee already had plans to address this concern with a new administrative.requireme~t training program to be implemented in the spring
. of 199 The inspectors noted that staffing of *the plant.Technical Staff had increased substantially. Staffing was regarded as a weakness in the last Systematic Assessment of Litensee Performance (SALP) perio The licensee.did not apply the Generic Letter 82-12 guidelines on overtime to the plant technical Staf Instances were identified where these guidelines were exceeded, most notably during the refueling-outage wi~h the ins~rvice testing/inservice inspection group~,.No problems were_ noted_ during non-refueling outage. period Safety Assessment/Quality Verification The inspectors noted that the rate of events*indicative of personnel performance problems decreas~d substantially duting the second half of the Unit 2 refueling outage as a result of licensee management actions delineated in inspection report 50-237/90023; 50-249/90023 *

Concern regardihg. the -
discovery of damage to the 'Unit 2,.SRM 22, following the suspen~ion of core alterations on November 12, 199 The damage resulted when the SRM was withdrawn during an instrument response chec~ and the drive mechanism came in*co~tact with an*tind~r vessel ~latform access hole cove The contact with the access cover resul~ed in the SRM beco~ing dislodged approximately three feet below the fully inserted position. Subsequent to the damage, fourteen fuel bundles were loaded into the SRM 22 core quadrant. Technical Specification 3.10.B. required SR~ 22 to* be operable and fully inserted to the normal operating level in the core during ~ore alterations in that quadtant of the reactor vessel~ Review of licensee fuel handling records revealed that SRM 22 did indicate the expected neutron response during fuel movement while the instrument was in a degraded cond~tio On November 6~ 1990, work was complted under the Unit 2 reactor to
.
install new SRM probe connectors per Work.Request (WR) 9543 Durin~ the probe replacement, platform access hole covers were utilized to minimize the potential for personnel injury.during the under vessel wor The work instructions accompanying WR 95435 did not address or control the use of the platform access cover However, a hand written memorandum was ~ssued to all instrument maintenance. (IM) supervisors req~iring that the access covers.be remo.ved prior to the withdrawal of any of the SRMs for the performance of the.instrument response check. Additionally, a caution tag was placed in.the control room instructing the operator not to withdraw the SRMs without first receiving permissio*n from the IM supervisor. This same methodology was utilized without incident during the previous Unit 3 refueling outag On November *12, 1990, operations personnel received erroneous permission from the IM supervisor prior to the ~ithdrawal and subsequent damage to SRM 2 Tri prevent ~ecurrence of this event, the licensee planned to tevise the applicable procedures to control the ~se of platform access covers Under the Out-Of-Service progra..
The failure to provide.adequate measures t"o prevent inadvertent operation*
.of the SRM drive~ in relation to the status of the platform covers is.
considered to be a violation (50-237/90027-0l(DRP)) of 10 CFR 50, Appendix B, Criterion XI However, the ~riteria of 10 CFR 2,.
Appendix C,Section V.G.l; for discretionary enforcement was*determined to be applicable and, therefore, no notice of violation is being issue The,tn~pector ltas. no further concerns i~ this are *

The inspectors identified six Appendi.x "R" emergency lights with the electrolyte level below *the add line. Dresden.Electrical Surveillance (DES) 4153-02,
"Emergency Lighting Month.ly Inspection", stated that "Electrolyte level shall be at the full line".* However, contrary to the established*
- procedure, *the liGensee.indicated _that a practice had been followed such that the,emergency lights need only be fil.led-when the* electrolyte level was at or belo~ the add line. The licensee further indicated that also contrary to the.established procedure~ the.determination to add distilled water was at the discretion of*the mainte*nance personnel *.

Plant Operations (61715, 71707 and 93702) *
The inspectors observed control room operations, reviewed applicable logs*
- and conducted discussions with. control room operators during this perio The inspectors verified the operabi 1-ity of.selected emergency systems, re.viewed tagout records an.d verified proper return to service of affected component Tours of Units 2 and.3 reactor buildings and turbine buildings were conducted to observe plant equipment conditions, including potential fire hazards, fluid leaks, and e~~essive vibrations and to verify that maintenance requests had been initiated for equipment in need of mairitenanc The inspectors rioted th~t general housekeeping and contamination crintrol had~deteriorated ~uring th~Unit 2 refueling outage as compared to recent* previous refueling outage The licensee planned to implement a new ma.terial condition/housekeeping/safety inspection program in January 199..
The inspectors identified that a licensee Quality Control inspector failed to don the required protective clothing while performing a hold-point inspection in a contaminated ar~a contrary to the requirements of Dresden Administrative Procedure (OAP} 12-25, "Radiation Work *Permit Process," Steps E.* 6 and F.1.e.5*, and Radiation Work Permit (RWP) OG067A, *
on*Oecember 3, 1990 *. * The individual subsequently became contaminated and alarmed the Personnel* Contamination Monitors (PCMs) when attempting to leave the Radiological Controlled Area (RCA).
Following receipt of the PCM a la rm, the individual' fa.iled to con.tact the Radiation Protection Department (RPO)~ per the requir~ments of OAP 12-13, "Personal ~xternal Contamination Surveys~" Step F.8.f,.and proceed.ed to perform self decontaminatio Fai~ing to foll~w the requirements of OAPs 12-13 and 12~25 in regard to radiation protection practices is considered to be a violation (50-237/90027-03(DRP)) of Technical Specification 6.2.B which required adherence to radfation control procedure~. Following a
discussion of the incident.with the inspectors on December 4, 1990, the individ:ual then notified the RP The RPO documented.the incident and completed the *appropriate corrective action of counselling the individual involved as to the proper health physics practices at the Dresden
Statio As this was considered to be an isolated occurrence, of minimal safety significance*and*the appropriate corrective action had been completed, a Notice of Violation is not being issued in accordance with 10 CFR 2, Appendix C~ Sectioh V.A~ The inspector has no further conce~ns in this are *
Each week during_ routine activities or tours, the inspector monitored the licensee's security program to ensure that ob.served actions were being
. implemented according to their approved security pla The inspector
- noted* that persons within the protected area* displayed proper
.
photo-identificati6n badges and those individuals requiring escorts were
- properly ~scorted. The inspector also verified that checked vital areas were locked and alarmed. Additionally,._ the inspector also verified.that observed personnel and packag.es ent~ring th.e protected area were searched bY, appropriate equipment or by han.
.
The inspectors performed a detailed walkdown of the acce~;ible portions of the Unit 2 containment *spray -system (CSS), which is a subsystem of the low pressure coolant injection* (LP.Cl) system *. The inspectors concluded that the CSS was. prop~rly aligned and in adequate condition. The inspectors.*
verified the pro~er positioning of.numerous is~lation*valves and electrical barriers in containment penetrations *. * In addition, the inspectors performed a walkdown of th~ drywell with licensee *personnel to ensure that material and equipment utilized duri_ng the refueling outage was
- properly removed*or* setured:

,,q.f.a veri,fication for.accuracy, correctness, and.compliance with regulatory reqli i rement *
The inspectors verified tha:t-the licensee_ had implemented contr'o.ls to
assure guidelines presented in Generic.L~tter.82-12, 11 Nuclear Power.Plant Staff ~orking Hours 11 were followed for licensed operators.. These
r*estrictions were delineated in DAP 7-21; 11Station Policy o*n Reactor Operatdr and Senior Reactor*Operator Manning Levels.and Overti~e,

- The licensee*.had developed an in-house* comput~r program which operations engineering *assistants utilized to track hours worked. and* to assure the. *
guidelines were met.. The licensee. identified*-four cases during the year of 1990 where these o~~rtime guideli~es had been exceeded~ Only one of these had bee*n pre-approved by management in accordanceJwith *OAP 7-2 The others involved administrati~e errors,_one of which occurred~. *
subsequent to utilization o'f"the computer tracking program 'implemented to correct the.se error*s and resulted from a *fai'lure of *operations engineering assistants to_ promptly enter -hours: into the compute '

Various pperational.occur~ences w~r~ also reviewed as follows: On flovember 23, 1990, with Unit 2.shutdown in a refueling outage, a
- scram was received due* to noise.spikes.on Intermediate Range Monitors (IRM} 13* and 15. All SRMs aQd IRMs actually received spike At the time, one cor:itrol rod was pa.rtially withdrawn for testing. The.cause was tdentified to be a voltage spike due to a faulty relay in the control logic for* the !.:ow Pressure Coolant*
I.njection (LPCI) syste The relay was replaced.* A similar occurrence with IRMs spiki~g high occurred on December 20, 199 The licensee has continued to investigate the cause of the spiking problem *

On November 27 1990, Unit 3 entered a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> limiting condition for operating (LCO) in accordance with Technical Specification 3~7. due to a failure of Nitrogen Makeup Valve A0-1601-5 During the nitrogen makeup surveillance, this valve.failed to close completel This was of concern since this valve also served as a containment isolation valve. Technical Specifications* would have allowed closing other valves upstream of this line to provide the isolation function such that the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> tCO would not have been entere However, one of these valves, A0-1601-58, was in.the pumpback system which provided drywell/torus differential pressure control. Since closing this valve would have caused difficulties in maintaining the required differential pressure, it ~as left open and the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> LCO was entere However, repairs were completed prior to actualJy initiating *a shutdow During a plant walkdown on December.?, 1990, *the.inspectors.. noted that an access door to the Unit 2 drywell purge and ventilation system downstream of ventilation fan 2-5708A, was open about one to two inche As. this formed a port.ion of the. secondary containment isolation boundary, the concern was that this provided approximate.ly a 72 square inch hole from *the' turbine ~uilding through this
.
boundar As described in paragraph 6.b., although Unit 2 was in a refueling outage, the current SGTS lineup would cause suction to be
.drawn from'this area. even if the actuat1on was on Unit 3. *It was not clear whether this breach was large enough to prevent f.ulfi llment of SGTS function (i.e., the"abil ity to pull a 0.25 inch differential pressure to the atmo$phere in secondary containment.)
The licensee ran the system with the access door in the as-found
- I
- .*,
condition' to ensure*thaf had the SGT*s been called upon, the suet.ion created in the ductwork would have pulled* the ~cces~ door shu As such, the inspectors ascertained that th_e operability of SGTS was
, not affected by -the open access doo No apparent cause cou_ld be
- ascertained by: the license *
'
- The inspectors a*lso note_d o.n December 7, 1990, that the Service Air
.Supply to three of the Unit-3 drywell purge and ventilation*fan
.dampers had been disconnected..
No temporary alteration tags were attached to the air lines or to the dampers' operators. Following notification to the licehsee, the. licensee reconnected the airlines to the dampers which changed position from open to close (The system was not in operation*_at th~ time~)
A revie~ of Dresden* operating Procedure (DOP) 6600-1, "Normal Venting of Drywell and Torus", Revision 5~ indicated that it require~ disconnectfon of the air operators on the drywell purge fan inlet and outlet dampers and blocking or tieing the dampers in the*
open_position prior to the operation. This was necessitated since the dampers automatically opened and closed in conjunction ~ith fan operation and the fan was not actualiy o~erated in this procedur A*step was also included to retonnect the air operator and unblock or untie the dampers when the operation was complet A review of the operating history of this system indicated that it was *last used for venting Unit 3 OR December 5~ 1990, for containment pressure control. This should.have been performed in accordance with DOP 6600- However, lt was questionable whether step E.1.b(2) was followed in that the air supply was found disconnected~ _This is considered to be an unresolved item (50 7237/90027-04(DRP)) pe~ding further review
. of operator involvement and safety significanc On December 8, 1990, while Unit 2 was in the refuel mode, eight
. *Group II automatic primary contai.nment isolation valves closed following the lifting of a field ~ire on a main control room terminal bloc The lead was lifted to facilitate* a resistance an me~gering check of the Main Steam Isolation Valve (MSIV) pilot solenoid cdils, per DES 200-39, "Main Steam Isolation Valve Electrical Maintenance." Further review indicated that an interruption of*multi~le neutral gro~nd circuits occurred when the lead was lifted. This resulted in a loss.of power to the associated
.seal-in relays, which maintained each of the -affected Group II isolation valves in their open positions *. Electrical wiring diagram 12E2697 indicated that the neutral ground circuit was *.
design~d to be wired,- in daisy chain fashion, on the _cabinet side of the respective *terminal bloc The drawing also showed four leads terminated on the cabinet side of the effected terminal point *

QES 200-39-matched the configuration as described on Diagram 12E269 When DES 200-39 was performed, the electrician found two leads on the field side ter~inal p9int. *The -lifti~g of the second lead resulted in the valve closure. The apparent root cause of the eveht was a discrepancy between the plant configuration. and the "as-built" drawing A rev*iew of past revisions to Diagram 12E2697 revealed_
that the origtnal plant de~ign tonfiguration also specified the
. termination of four leads on the cabinet side of the terminal block point. -Based on the physical limitations* of the cabinet side terminal block point~ the undocumented wiring tonfiguration was estimated to*
have existed since initial plant startup.. This is consider~d an unresolved item (50~237/90027-0S(DRP)) pending NRC review of licensee
- corrective action The licensee failed' to recognize that closure of the Unit 2 Group II containment isolation valves was an ESF actuation and also failed to make the four hour report to the NRC as required per 10 CFR 50.7 The licensee indicated that the rationale for not reporting was that the loss of power occurred in the control circuitry and not the logic circuitr In other words, the logic circuitry did not de-energize to open a corresponding contact in the control circuitry to cause the closur As such, the licensee did not classify this as an ESF actuation. The 1 icensee based *this distinction on NUREG 1022, "Licensee Event* Report System,"Section V, which stated. the following:
Actuation of mult,ichannel ESF Actuation Systems is defined as actuation
_of enough channels to complete the.minimum actuation logic ( activation of sufficient chann~ls to cause activation of the ESF Actuation System).
T~erefore, *single.channel actliations, whether caused by failures or. otherwise, are* not reportable if they do not complete the.minimum actuation logi,-,

'.
It was evident that the li'censee had inferred a meaning that was not intended nor supported by the other *portions.of* NUREG 1022 or its *
supplement The paragraph noted by the licensee w~s.intended to *
specifically explain the non-t"eporta~i'lity of.*single channel actuations versus**multichanriel-actuations. *No further meaning can be inferred and, iri fact, this.paragraph made rio.attempt to define
- the logic portion of* the circuitry. as separate and distinct fro*m
. other portions of the actuation circuitry (i.e. control circuitry).
Section IV of NUREG 1022 provided* a* restatement of the guidance for 10 CFR 50.73 from the statement of consideration which indicated that the criteria were based on the nature, course and consequences of the e~ent and not 6n initiating events or.causes of event In addition,Section V of NUREG 1022 indicated that the NRC was interested in both events where an ESF*was needed and events where an.ESF operated unnecessarily since they should not be.challenged frequently or unnecessarily;
.
.
10 CFR 50.72(b)(2)(ii) specifically.required the* reporting of any condition that results in a manual or automatic actuation of any Engineering Safety Feature (ESF).
Additionally, 'NUREG-1022,
"Licensee Event Report' System," Supplement No. 1,Section II.6,
. clarified that an ESF actuation includes any automatic, spurious, or manual action that results in the actuation of the device to perform its intended functio In the case of the Group II-isolation valves, the intendeq ESF safety function was the automatic closure of the valves. All ESF actuations were required to be reported (except those expected actuations that result from and w.ere part of preplanned sequence during testing)..
The~failure to make the required report was considered to be a violation (50~237/90027-06(DRP))
of 10 CFR 50.72(b)(2)(ii).

b. * On November 30, 1990, ihe lic~nsee.identified a problem with.the SGTS lineup which could* potentially allow *flow to bypass the SGT *Among other locations; the SGTS took a suction from each unit's reactor buflding v~ntilation system.. (RBVS).
In 6rder to address a problem identified in the mid-1970i, *the licensee had *tagged the reactor building ventilation to SGTS isolation valves open with their corresponding breakers racked out such that they would not
- close on an automatic signal. The original design called for the isolation valve on the unaff~cted unit to.automatically close on *a*
SGTS automatic start signal. This.was to prevent flbw from.the affected unit's RBVS from entering the still *normally operating RBVS
- on the unaffected unit,* which would exit to the environs without passjng through the SGT The liCensee was. concerned that following an initiation signal on one unit and corresponding closure of the opposite unit's RBVS to_SGTS isolation valve, an ~utomatic start signal on the other unit would then result in total isolation of.the SGT Therefore, a single failure could disable the SGT The licensee could find no record of a 10 CFR 50.59 safety evaluation for the racked out isolati6n valve breakers~ The li~ensee. had planned on modifications to*th~ logic to address the original*
concerns but the modifications were cancelled pr_ior to implementatio The licensee indicated th~t justification*was that operator actions could be taken to initiate reactor building ventilation isolation on the unaffected unit when an automatic signal was received on the opposite unit. This was reflected in procedures such that' the o~posite unit's RBVS would be manually lined up to the SGTs*o~ a single unit.initiati9n signal.. While reviewing applicability of motor operated.valve testing to these valves on November 30~.1990, lic~nsee p~rsonn~l reviewed these previous actions and questioned whether adequate justification had been utilized. The licensee conducted an offsite dose analysis assuming no operator actions with both isolation valves remaining open. These results inditated doses ~ell below 10 CFR 100
. *
guidelines. The licensee.. planned to develop a modificati6n that would cause both RBVS to automatically lineup to the SGTS on a
- .single unit initi.ation. - The licensee also planned to perform a review of existing out:..of-services *to ensure that similar long standing cases of system changes through out-of-service did not exi.s As indicated in enfor*cenient conference report 50-237 /90023; 50-249/90023, the licensee also was developing reforms to the
10.CFR 50.59 safety evaluation proces*s at the fac.ilit "'..
- t
Although the facility change was.perfo.rmed through a.n out-of-service, the nature and long ~term existence cle~rly i.ndicated the necessity
. of performing a lO CFR 50.59 safety evaluation to ensure that an unreviewed safety que-stion did not e.xis In addition, the inspectors*
considered the justification* for c:ance ll ing modifications to rectify the various concerns to be inadequate-in that an appropriate basis was not provided a~ to utilization of mariual operator attions in place of the automatic functio Failure to maintain records, which include a written safety evaluation of this -facility change, is considered to be a violation (50-237/90027-lO(DRP)) of 10 CFR 50.59(b)(l).
However, as.this issue was licensee identified, an unreviewed safety
- question by definition did.not actually.exist, appropriate corrective actions were initiated or planned and due to *the age of the initial change, a notice of vi6lation is not being issued in ac~ord~nce with
. exercise of discre~ion delineate~ in lO*CFR 2, Appendix t,Section V. *

swi.tches on the control valve fast acting solenoids which.Provided the scram signal were replaced by pressure switches which actuated on.low Electrohydraulic Control (EHC) oil pressure.at each control valve. Technical Specification Table 4.1.1 required a functional che~k s~rveillance to be performed on this scram functio However,_
Technical Specification Table 4.1.2*did not require a cbrresponding calibration check to be performed sJnce it actually was written for the old design. Technical* Specification Ba~is indicated that this was, in fact, an "on/off" type swi,tch for which calibration was not applicabl However, the "new design" pressure switches can be calibrated. Since it was not required, the licensee was unsure whether calibration of these.switc~es had ever been performe Since the licensee had performed ~equired functional checks but.not necessarily calibration* checks on this SCl'.'am function, its

operability was questionabl The generator load reject scram wa.s a limiting safety *syst~m setting which anticipated the rapid increase in pressure and neutron flux from a contrbl valv~. closure due to load rejection coincident with a 'failure of the bypass valves and corresponding Minimum Critical Power Ratio (MCPR) consideration This was riot an inunediate pr_oblein since TecHnical Specifications allowed this scram function to be bypassed at less *than 45 percent steam flo Unit 2 was stfll shutdown for a refueling outage and

This commitment indicated that the NOD would provide guidance *applicability beyond the Techni ca 1 Specification minimum shift crew composition and that included in this would be maintenance personnel and chemistry and radiation protection personne As su.ch, the commitment was not clear as to what other groups beyond those specifically m.entioned would also be include The commitment also indicated an appropriate level of management would be.. de~ignated to assure that overtime was approved prior*to
