Waddington, Jr., Coordinator, Emergency Communications The inspectors also interviewed and/or observed the actions of other licensee personnel. 2.0 Emergency Exercise The Limerick Generating Station (LGS) partial-participation exercise was conducted on November 24,1992, from 8:00 a.m. to 2:00 p.m. The Comr9nwealth of Pennsylvania partially participated in the exercise by sending representatives to the Emergency Operations Facility. Off-site activities were not inspected. - -
. . 2 2.1 Pre-exercise Activities Exercise objectives were submitted to NRC Region I on August 21, 1992 and the complete scenario package on September 23, 1992 for NRC review and evaluation. Region I representatives discussed the scenario with the licensec's emergency preparedness staff on October 23,1992. The scenario was assessed as an adequate test of the major portions of the Emergency Plan and Implementing Procedures. NRC exercise observers attended a licensee scenario briefing on November 23,1992. The scenario was discussed in depth and all NRC observer questions were answered. The lleensee stated that certain emergency response activities would be simulated and that controllers would intercede in exercise activities to prevent disrupting normal plant activities. 2.2 Exercise Scenario ; The scenario provided a challenging test of the I.GS Emergency Response Organization's (ERO's) ability to analyze and mitigate a severe accident. Information in the scenario package was excellently presented. The exercise scenario included the following simulated events: * Initial conditions: Unit I was operating at 100% power for the last 150 days. Low Pressure Coolant Injection Loop 1 A, Standby Liquid Control Pump IC, and the Reactor Core Isolation Cooling System were out of service. Fuel pin leakage resulted in off gas noble gas activity of 700 uCi/sec, which increased after a recent rod shuffle. , * Increase in off-gas activity to 5C50 pCi/sec. * Break in a frecic seal supply line, resulting in release of nitrogen inside the power block, and an Alert. * Clogged Control Rod Drive Pump suction filter. * Spurious High Pressure Coolant Injection actuation due to a failed controller, resulting in minor clad damage, reactor scram, and Group 1 Main Steam Isolation Valve closure. * Failure of Source Range Monitors and Intermediate Range Monitors to insert into the Core. * Failure of Residual Heat Removal System heat exchanger l A inlet valve to open. * Steam Relief Valve failed open. , * Total loss of annunciators (a Site Area Emergency).

.
* Exercise termination. 2.3 Activities Observed ! The NRC observed the activation and hugmentation of the Emergency Response Organization, activation of Emergency Response Pacilities, and actions of emergency response personnel. The following were observed: + 1. Selection and use of control room procedures. 2. Detection, classification, and assessment of scenario events. ' 3. Direction and coordination of emergency response. 4 Notincation of licensec personnel and off-site agencies. 5. Communications /information flow, and record keeping. 6. Assessment of off site consequences, and protective action recommendations (PARS). 7. Technical support, repalts and corrective actions. ; 8. Communication with the media and the public. , 9.. Accident analysis and mitigation. ; 10. Accountability of personnel. 11. Post-exercise critique by the licensee. 3.0 Exercise Finding Classifications * Emergency preparedness exercise findings were classified as follows. Exercise Strength: A strong positive indicator of the licensee's ability to cope with abnormal plant conditions and impicment the Emergency Plan. Exercise Weakness: Less than effective Emergency Plan implementation which did not ofitself constitute overall response inadequacy. Area for Improvement: An aspect which did not significantly detract from the licensee's response, but which merits licensee evaluation for corrective action.

Activatkr and utilization of the Emergency Response Organization (ERO) and Emergency Response racilities (EAFs) weie consisters. with 'he Emergency Pian and Emergency Plan Implementing Procedura. ,e The licensee used their control nmm simulator in the dynamic mode, The lack ofignlGeant exercise control discrepancies (i.e. com 'ter communications allowed timely removal of
'
simulated faults based on player resport .iowed attention to detail in scenario development and prediction of player responses. The / ice President of Limerick was present in the ems during the exercise and the Senig Vice President, Nuclear, attended the critique and exit _ meeting, showing licensee management commitment to EP. 4.1 Simulator Control Moom (FCR)
.
SCR operator response to simubled casualties was prompt and effective. Good teamwork was demonstrated. The crew quickly recognized abnormal conditions such as the inadvertent High Pressure Coelant injection System initiation, stuck open safety relief valve, failure of the source and intermediate ange detectors to insert, and tailure of two law Pressure Coolant injection System valves to yen. Procedure use was excellent. Operators effectively established response priori'i's for equipment failures. The Eft branager (SM) and Shift Supervisor (SS) exercised excellent command and untrol. The SM correctly classiGed the Alert, and notifications by the shift were timely. SCR internal communications arp those with the Technical Support Center (TSC) were good. Ilowever, the SM did not imht.u bis crew when he became the Emergency Director or when that duty was transferred to the TSC. _ The SCR controller noted that Procedure ERP-101, "Clanincation of Emergencies," was not the correct revision. The carect revision was krated and provided to the operators. The following exercise strengths were observed: * SCR command and control. * Prompt recognition of abnormal plant conditions. * Use of procedures. No exercise weaknesses were observed. , p The following area for improvement was identined: * Assuring use of current procedures. 1 . . . . . . . . _ . .. . . I

, 4.2 Technleal Support Center (TSC) ;
The TSC was prepred for um by procedure and activated in 9 timely manner. The Emergency , l Director (ED) briefed his staff and ensured status boards were up to-date beibre activation. The ED exhibited stroag command and control. He maintained r,ood communications with the Simulator Control Room and the Emergency Operations Facility, conducted regular team leader rnectings with his staff, and gave frequent and thorough brienngs to facility personnel. The sit i team leaders provided excellent feedback that resulted in sound decision making and proper establishment of priorities. l l Evrti; c!assi!kations for the Site Area Emergency and General Ernergency were correct and I notineatons of off site ofncials and the NRC were timely. Status boards wc:e frequently l 1 ugJawd and accurately prescitated event data. The following exercise strengths were cbserved: * ED command and control. * ED use of staff for decision-making. No exercise weaknesses or areas for imprevement were identified. 4.3 Operational Support Center (OSC) OSC activation was timely. The OSC Coordinator (OSCC) demonstrated good command and
'
control. Telephone and radio communications were timely for maintenance team coordination. Sufficient personnel were available for plant needs, and the OSCC was proactive in dispatching teams for repairs and investigation. . The OSC demonstrated excellent accountability. Personnel were required to check in and out
l
with the OSCC, who maintained a list of available people for maintenan:e and health physics functions. Personnel also p&ed accountability cards on the OSC tagboard and carded in and out when entering and leaving. Furthe , personnel were logged in and out on thejob assignment
( stitus board. 1 L The OSCC gave periodic bne6ugs to OSC personnel, but these were brief and cursory. No L information was provided on event dassification, status of events, work prioritit.s, recommended

l
protective actions, or dispatei4ed tean updates. The OSCC was very busy with phone chils, radio communications, log keeping, team briefings, and facility briefings, in addition to command and control duties. AH, the ordy record of team briefings and debriefings was
i
maintained on status boards, ar4 w permanent records were kept.

The following areas for improven*?r;! were noted: * Facility status briefing quality. * Number of duties assigned to the OSCC. * Permanent records of team briefings / debriefings. 4A Emergency Operations Facility (EOF) Personnel staffed the EOl at the Alert level, and the facility was activated ai use Site Area Emergency. The EGF was activated in a tims.y manner. The Emergency Response Manager (ERM) assumed control after a thorough turnover from the ED, providing a plant status update to EOF staff, and receiving reports from his team leaders that sufficient personne) were avidlable.
. The ERM used his staff effectively to assess plant problems, core draage, and radiological
conditions on-site and off site. Ile interfaced well with the Dose Assessment Team Leader and the Dose Assessment Group Leader to keep them apprited of changirig plant > conditions, and thoroughly discussed protective actior recommendations (PARS) with thena before issmtnce. He frequently communicated with the Commonwealth of Pennsylvania representative.s from the Bureau of Radiation Protection and the Emergency Management Agency by briefing them on plant conditions, discussing PAR declarations and their bases, and resporJing tci requestb for information. The following exercise strength was identified: e ERM command, control, and communications. There were no EOF exercise weaknesses or areas for improvement. 4 A,1 Protectise Action Recommendations (PARS) A loss of Coolant Accident (LOCA) occurred at 1056. At 1110, orywell radiation levels reached 10,000 R/hr., leading to a General Emergency declaration. After thomugia discussion wlth his staff, the ERM issued a PAR for evacuation of thc two mile radius and five miles downwind. Pour downwind sectors were relected based an a projecte41 wird shift to th: south. This PAR was consistent with federal guidance and licensee procedures.

.
7 At 1132 the Commonwealth of Pennsylvanir declared a State of Disaster. At 1140 the ERhi announced that the Commonwealth of Penn 'vania had decided to evacuate the full ten-mile Emergency Planning Zone. At 1146 discussions between the ERh1 and Dose Assessment Team Leader (DATL) concluded that a PAR change was needed to reflect the change in wind direction. Additionally, drywell radiation levels were increasing, so the ERht discussed with the DATL whether a PAR extension was warranted. The ERh1 and DATL decided to wait until drywell radiaticn levels reached 50,000 R/hr. before extending the PAR. The existing PAR was changed by rotating the downwind sectors north by two sectors. To do so, a recommendation of evacuation was withdrawn in two sectors and provided in two others. No release was in progress at this time. EPA-520, "hianual Of Protective Actions For Nuclear incidents," Chapter 5 Section 5.2, points out that " Withdrawal of protective actions from areas where they have already been implemented is usually not advisable during the early phase because of the potential for changing conditions and confusion." Inspector review found no procedural direction concerning withdrawal /rnodlGcation of PARS due to wind shifts. At 1200 the release started. With main stack readings increasing, the ERhi discussed updating the PAR with the DATL. When drywell radiation levels exceeded 50,000 R/hr., the ERhi issued a PAR of evacuation of the nye mile radius and ten miles downwind. This PAR was consistent with licensee procedures. The PAR change due to the wind shift and the absence of procedural guidance for this action was assessed as an area for impravement. 4.4.2 Dose Assessment, Field Teams and Air Sampling Overall, the dose assessment staff parformed well. They proactively projected doses based on postulated failures, and good figures were available prior to the Loss of Coolant Accident -(LOCA). The ERhi directed the DATL to provide a dose projection dt.e to a planned drywell purge. This was initiated based on a four-hour release. The DATL later decided to confer with the engineering staff for a more accurate release duration. Licensee field team samples verined the validity of projected doses. Severallicensee air samples were taken to determine the iodine release. The DATL remained cognizant of possible protective actions for emergency workers in the plume. (t his scenario did not necessitate the use of potassium iodide.) The Field Survey Group Leader maintained good control of the field teams. No field team communication discrepancies were observed. 4.5 Emergency News Center (r.NC) ENC activation was timely. All news releases were reviewed for accuracy and approved by the ERhi before release, hiedia briefings were held frequently and the information presented was ! - - _ __ a

. . 8 discussed with Pennsylv mia representatives beforehand. The Corporate Spokesperson conferred with the ERM prior to each media briefing to ensure that his information was correct and up to date. News briefings were conducted in a controlled manner and the simulated media asked gcal questions. The one actual media person present, his, hielissa Dribben of the Philadelphia Enquirer, was given a facility tour by the licensee. 5.0 Previously identitled items Closed (IFI 50-277/9212 01) The NRC had identified two weaknesses in EOF / ENC performance at the Peach Bottom annual exercise on August 26,1992 (Inspection Report 50-277,-278/92-19). As a result, the licensee scheduled a management meeting with the NRC on September 17,1992 (Agenda attached) to discuss corrective actions. An NRC inspector observed the Limerick dress rehearsal drill from the common Peach Bottom / Limerick EOF / ENC on October 14,1992 to observe the effectiveness of correcuve actions. At that time, the licensee gave the inspector a more detailed list of planned corrective actions (copy attacted) for the EOF / ENC, and draft copies of planned procedure changes to be used in the dress rehearsal and the Limerick November 24,1992 annual exercise. NRC inspection of EOF performance during the Limerick exercise assessed EOF performance in relation to the Peach Bottom exercise weaknesses. The following is a summary of specific corrective actions observed during the Limerick dress rehearsal and annual exercise. * Company vice presidents and one general manager were trained to be Emergency Response hianagers (ERhts) instead of senior plant management. The Vice President, Peach Bottom functioned as ERht for both drills, and there was notable improvement: ERh! command, control, and communications was a strength in the Limerick exercise. * New Corporate Spokespersons (css) were trained: A newly trained CS filled that position for both drills, with marked improvement in Emergency News Center function. * Training for ERMs, Assistant ERMs, and dose assessment teams in the areas of protective action recommendation (PAR) development, PAR upgrade, and release pathway assessment was improved as follows. a. PAR procedures were changed to reflect current guidance (NRC Response Technical hianual, RTht-91) for severe core damage, and to require the ERht to consider plant status and dose assessment in PAR development as well as to provide a copy of the PAR development sheet to State representatives. b. Canned PAR upgrades were provided consistent with NUREG-0654 guidance, c. Assessment aids for release pathway analysis were developed and placed in the . . . . ~ _ _ -- . . _ _ - - - . . . . .

. 9 EOF and TSC for use by dose assessment teams (Attachment 3). d. The interface between EOF and TSC dose assessment was clarified. The TSC team now continues as a dose assessment resource after turnover to the EOF. * ERh1 review of press releases is now required. This brought good results. The CS regularly conferred with the ERhi for plant status updates and approval of press releases. * The following emergency response procedures (ERPs) were revised to clarify expected actions such as potassium lodide prioritization, PAR development and upgrading, EOF- TSC dose assessment team interfaces, and ERh! approval of press releases, a. ERP-101, Classification of Emergencies b. ERP-C-1200, Emergency Response hianager c. ERP-C 1300, Emergency Operations Facility (EOF) Dose Assessment Team leader d. ERP-C-1310, Emergency Operations Facility (EOF) Dose Assessment Group c. ERP.C-1320, Emergency Operations Facility (EOF) Field Survey Group leader During the Peach Bottom exercise, EOF command, control and communications problems resulted in non-recognition of the release pathway, in PAR formulation Daws, and in absence of consideration of potassium iodide for use by Held teams. During the Limerick exercise, EOF command, control and communications were an exercise strength. The release pathway was correctly diagnosed, PARS were appropriate and, although iodine was not a factor in this scenario, its potential use was discussed and the licensee had changed procedures to highlight the importance of potassium iodide for personnel safety. Therefore, the Peach Bottom exercise weakness was shown to have been corrected. Closed (IFI 50-277/92-19-02) Accuracy of information disseminated. During this exercise, news releases were accurate and were approved by the ERhi before dissemination. The following areas for improvement identined during the previous annual Limerick emergency exercise (Inspection Report 50 352/91-07; 50-353/91-08) were acceptably demonstrated. Simulator Control Room: * Senior Emergency Response Organization manager prepositioning. * Delay in requesting off-site emergency services due to communications burden. * Entries not made in bound log books when events occurred. Technical Support Center: * Uncertainty of low Pressure Safety System set point pressure. * Consideration of useful operational life of Stand-By Gas Treatment System.

10 i Operations Support Center: * Sufficient emergency communications equipment availability. l Emergency Operations Facility: ; e implementing Procedure uw. 6.0 Emergency Action Level (EAL) Change The licensee revised ERP-101, "Classincation of Emergencies," Table 4.2, Appendix 11, "lloundary Degradation /LOCA" prior to the exercise. The nrst General Emergency (GE) condition in this category previously read: 1) Scram with LOCA M no ECCS, Indicated by: a. Failure to bring Reactor level above -129" after 3 minutes, b. m Containment pressure greater than 20 psig. . The revision (Revision 1) changed Rem "a" to read: a. Failure to bring Reactor level above -161". NRC review concluded that Item "a" in the new revision was potentially confusing since it is unclear as to when the condition is met. The revision provides no literal obligation to declare a General Emergency if reactor water level drops below -161" (i.e., top of active fuel) as long as level is restored to that value in some unspecified time period. This concern was expressed to the licensee at the exit meeting. Also, the licensee identified this item as an important area for improvement during their formal critique of the exercise. The NRC subsequently requested and received from the licensee their 10 CFR 50.54(q) review and 10 CFR 50.59 safety evaluation for this change. This issue will be further reviewed (IFl 50-352,353/92-28-01). 7.0 Licensee Critique and NRC Exit Meeting On November 25,1992 the NRC team attended the licensee's exercise critique. Lead controller:; summarized the licensce's observations. Each area was evaluated for: strengths /significant improvements, areas for improvement, and recommendations. The critique was thorough, identined most NRC findings, and was assessed as a good self-examination. After the critique, the NRC team met with the licensee (see Detail 1.0 for attendees) to discuss the inspection findings. The team leader summarized exercise strengths and areas for improvement. The lleensee was informed that there were no exercise weaknesses and that their exercise performance demonstrated the ability to implement the Emergency - Plan and implementing Procedures to protect public health and safety. Licensee management acknowledged NRC findings. The licensee concurred with the NRC areas for improvement associated with the OSC, said that the OSC was already being evaluated for improvement, and commented that all NRC findings would be evaluated for appropriate action. . . . .- .. - - _ - - _ - . - -.
