MCGUIRE EMERGENCY PREPAREDNESS EXERCISE (Ins'pection Report #50-369,370/90-15)

August 14-15, 1990 A. Name: Glenn-Arthur B. Assignment: Control' Room (CR) for. medical drill on August 14; Simulator CRandTechnicalSupportCenter(TSC)onAugust15.

'C. Site Personnel Contacted: B. McRee, Exercise Director; D. Miller, Lead Controller, Simulator CR; C. Jennings, Lead Controller TSC; R. Tracey, Shift Supervisor (SS) - Medical Drill; A. Perdue, Senior Reactor Operator (SRO), Medical Drill; W. Johnson, Communicator for Medical. Drill'=and -

Exercise; G. Pickler, SS -Simulator; T. McConnell, Emergency Coordinator (EC); R. Leonard, Emergency Preparedness Director D. Positive Findinos

• The SS and SR0 for the medical drill- and all members of the j simulator CR shift performed exceptionally well. Detailed use of l

procedures, coordination between individuals, and_ good. command and l l

control were demonstrated in a quiet, competent manner.. l l

• -The EC and his assistants in the:TSC worked as a highly knowledgeable and smoothly functioning team. Pcoblems were aggressively pursued, potential solutions evaluated, and alternative proposals generated. Proposals were evaluated with approximate time lines to establish priorities. A highly effective,~ professional management atmosphere existed.

• Coolant sampling procedure does not exist for overriding or

! i bypassing isolated sampling valves. The inabili.ty to obtain a sample prevented core damage assessment.

'

• Excessive use of the announcing system by the EC in the TSC resulted in personnel apparently igt...ing his announcemt .cs. At one point, there were three different groups having intensive conversations / '

discussions immediately adjacent to the EC's desk during.one of' hic announcements.

• The clocks in the TSC were not synchronized. Two- and four-minute differences were noted between three clocks in the TSC, EC area, and dose assessment area.-

• A plot of the radiological plume was not posted in the TSC. -The i

radiation monitoring field teams reported information to be used to  ;

generate a plot and a plume discussed, but the visual plot'was not established.

Swipes for determining contamination levels and personnel radiation monitoring of personnel returning to the Operational Support Center (OSC) and TSC hallway were warranted, but not performed. .0SC teams were dispatched to areas in-plant where contamination should have been expected for this scenario.

The capability to trend critical parameters was nct demonstrated.

An attempt to keep track of various pressures, temperatures, and levels of importance on a status board was made, but it confused

, -rather-than clarified the rate of change of different parameters.

0855- -Arrived in CR.  !

0912- SS in CR notified of three personnel. injured in new building containing shredder; SS stated it was a drill. ,

0943 SS heard on in-plant radio system that an ambulance was >

entering the protected area. SS had not been notified that an ambulance been requested. He heard on the radio that a second ambulance had been requested.

0949 SS informed by telephone of the' individual personnel injuries and that all were contaminated.- SS will be notified if i 1

injured personnel requiring hospitslization can not be decontaminated prior to transfer by. ambulance to the hospital.

1007 SS notified that an injured contaminated man had to be transferred by ambulance to a hospital. Emergency Action l Level (EAls), event classification, and eme'rgency notification procedures immediately obtained and put into use. I 1 1 i

1010 Medical Emergency Response Team-notified SS that two contaminated, injured men were being t'ransferred by ambulance to Charlotte Memorial Hospital. 'SS -directed SRO to notify;  !

hospital that these two men would be arriving.

1011 Checklist.being followed and-Emergency-Notification form being l

l completed. Unusual Event (UE) declared.

Leakage is 50 gpm or greater. SS declares an Alert. SS is q filling out emergency notification' message. Procedures beiu, .q followed and good communications and cooperation by all shift ,

personnel.

1132 SS informed that resident inspector heard page'and is.enroute ,

voice and procedure use by the communicator.

1139 Notification completed except for county that did not initially respond. Call-up made and notification.being made to that county.  !

i 1144 Plant Manager arrivod 'in CR. Being briefed by SS, who is i- using Alert procedure and relief check-off lists. l 1149 SRO checking EALs to determine if radiation alarms existing. 1 would qualify for classification upgrade. Plant Manager told no other EALs are currently being met.

1153 Plant Manager has relieved as Emergency Coordinator, after ai thorough review of plant status, good use of check-off sheets,.

and status reports on procedures being'used.

'l Time: Observation

' 1318 = VC/YC (CR cooling system).is out.of commission due to low oil. l A maintenance person has suffered heat exhaustion, not (

1355 EC on PA. SAE conditions still exist. Approximately 1% fuel damage has occurred. PARS may be necessary,'due to continued I discharge resulting-in accumulated dose to personnel offsite.

L 1415 Level in C SG increasing. Person dispatched to see if relief valve is shut.

1416 EC announces that indication of nuclear. reactor coolant system (RCS) and C SG pressures-equalizing indicate the' steam valve that lifted has reseated. C SG release has been cerminated.
