(Closed) Open Item No. 50-483/87017-01: During the 1987 exercise, the onsite portion of the medical drill was inadequate with respect to various contamination control practices and other aspects of Emergency Implementing Procedure (EIP) EIP-ZZ-00224. As indicated in Section 5b of this report, the licensee's performance during the onsite medical drill portion of the 1988 exercise was very good, and responsive to the concerns identified during the 1987 exercis The inspector also reviewed records relevant to the upgraded training

,given to the licensee's Medical Emergency Response Team (MERT) personnel-daring 1988, and discussed medical program upgrades with cognizant licensee representatives. Since the summer of 1987, a Site Nurse has

been available onsite during day shifts on weekdays. The rurse's current contract is up for renewal this summe Records indicated that the nurse held monthly meetings with MERT team leaders to discuss relevant topics and to conduct additional training on providing medical care, including taking blood pressure readings and administer oxygen. More frequent informal meetings have been held with available MERT team member Since January 1988, eleven onsite medical drills have been conducted and critiqued in addition to the demonstration during the annual exercis Approximately 90% of-all personnel.who are designated MERT team leaders or members have participated in at least one of these drill Drills were adequately documented, and included participants lists, objectives, scenarios, critique comments, and references to the licensee's action iterr. tracking s3 ste The licensee also indicated that first aid kits and contamination control kits used by the MERT have been upgraded since mid-198 The licensee indicated that these kits were being inventoried quarterly and af ter each use. Inventory records were not reviewed during this inspection._ The licensee has scheduled a plant tour for about 25 hospital and ambular.ce service staff later in June 1988. An agreement was being negotiated with the University of Missouri at Columbia to make available a "Staff for Life" helicopter service to provide improved capability to quickly transport onsite personnel to a regional hospital.

(- This item is close . General An off hours exercise of the Callaway Nuclear Power Plant Emergency Plan was conducted on June 6, 1988, testing the licensee's response to a

[ hypothetical accident scenario resulting in a simulated release of l

radioactive material to the environment. The attachments to this report consist of a narrative summary and approximate timeline of the scenario, and a listing of the licensee's exercise objective This was a full scale exercise for the acate of Missouri and a full scale exercise for Callaway, Gasconade, Montgomery, and Osage Counties.

l 4. General Observations Procedures This exercise was conducted in accordance with 10 CFR Part 50, Appendix E requirements using the Callaway Plant Emergency Plan and related Emergency Implementing Procedures, Coordination The licensee's response was generally coordinated, orderly, and timely. If scenario events had been real, actions taken by the licensee's emergency organization would have been sufficient to allow State and local officials to take appropriate actions to protect public health and safety.

c, 0bservers Licensee observers monitored and evaluated the exercise along witn the NRC observers, Critiques The licensee held critiques immediately following the exercise and a summary critique was also conducted on June 7,1988. A publi critique was' held that evening in Fulton, Missouri, at which time NRC and FEMA evaluators summarized their preliminary findings regarding th; licensee's and offsite support agencies' exercise performances, respectivel . Specific Observations (822301) Control Room Simulator The Control Room crew demor,strated good teamwork and responsiveness to changing abnormal plant conditions. Communications among the crew were done in a professional manner. The Senior Reactor Operator-(SR0) kept the Shi*t Supervisor (SS) well informed of changing conditions. The Shift Technical. Advisor (STA) was effectiv31y utilized in trending key parameters, monitoring safety systems' status, and was actively involved in various decisionmaking discussions. Piant drawings were well utilized during problem evaluations. Emergency operating and emergency plar implementing procedures were correctly followed with one minor exception. At about 7:25 p.m., an automatic main steam line isolation actuation signal was received. ' This could have been avoided had the crew observed a procedure caution note on blocking the signal. The actuation resulted in a simulated, brief loss of secondary coolant through the steam generator relief valves. The crew promptly and correctly responded to the actuation signa The SS adequately briefed the Superintendent of Operations and the Emergency Duty Officer (EDO) upon their arrival in the Simulato These individuals became involved in various discussions, but properly did not assume control of response activities from the S The E00 later became the Emergency Coordinator (EC) in the Technical Support Center (TSC), and assumed command and control of onsite emergency response activities from that facilit The SS promptly and orrectly classified the Alert and Site Area Emergenc Initial i.otifications to State, county, and NRC officials were accurately completed within the regulatory time limit The SS approved the initial message forms prior to their transmittal by communicator Based on the above findings, this portion of the licensee's program was acceptabl _ - -

b .- Onsite Medical Orill The scenario began with a simulated medical emergency within the Radwaste Building. An employee had fallen off a ladder and broken his right le The worker's wound and protective clothing had become contaminated by the time that he had been removed from a pump room to a nearby area where medical assistance was requested by a co-worker.

, The Medical Emergercy Response Team (MERT) arrived at the victim's location approximately five minutes after the accident had been i reported to the Control Room Simulato The HERT leader demonstrated good, decisive leadership until the victim was transferred to an ambulance for transport to the local hospita The MERT exhibited good teamwork, and good understandings of their medical treatment and contamination control responsibilitie The MERT arrived at the victim'.c location equipped with first aid and contamination control kits. The team donned shoe covers and gloves upon seeing the victim. While the MERT leader and one assistant aegan their initial evaluation of the victim's condition, other team members adequately defined and posted the borders of the contaminated zone around the victim. The contaminated zone's boundary was reduced following more thorough surveys. A continuous air sample was taken near the victim, but not so close as to inhibit care being administered to hi One technician and a security guard remained outside the contaminated zone. During the demonstration, the guard provided valuable assistance by communicating frequent updates on the victim's medical and contamination status to the Central Alarm Station (CAS), which forwarded the MERT's reports to the Control Room Simulator. The guard also kept the MERT well advised of incoming messages regarding the whereabouts of the ambulance and six stretcher bearers which the HERT leader had requested. The stratcher bearers ultimately arrived, an unacceptable 30 minutes aft.r they had been requested. Post-exercise investigation of this delay revealed that it was largely due to the artificiality of the exercis At times, CAS staff initially telephoned the MERT's reports to controllers in the Control Room Simulator rather than placing the calls to the Shif t Supervisor's telephone in the Simulato Had scenario events been real, procedures allow anyone at an accider.t scene to communicate directly with the real Control Roo While caring for the victim, the MERT leader and several aides demonstrated good contamination control techniques. Gloves were changed at appropriate times to avoid spreading contamination on the victim or on medical equipment, which was surveyed between use. The medical kit arid supplies removed from it were placed on a clean plastic blanket to further avoid it becoming contaminated. The victim was checked for other injuries and was never left alon The MERT bandaged the wound, applied a leg splint and a neck brace, and

administered oxyge He was carefully placed and secured onto a collapsible backboard, which had first been kept on a clean plastic blanket to avoid contaminating its undersid The MERT was preparing to carry the victim up three flights of stairs when the stretcher bearers and two medical technicians from the ambulance arrived at the victim's location. The medical technician's wore personal dosimetry. They received an adequate briefing from the MERT leader on the victim's medical and contamination status. The medical technicians and stretcher bearers remained on the clean side of the contaminated area boundary. The victim on the backboard was carefully transferred across the boundary, and additional surveys of the backboard were performed to better ensure that its underside was not contaminated. The stretcher bearers carried the victim up the stsircase and outside the Radwaste Building where the victim and the backboard were secured on a gurney and loaded into the ambulance. Due to the contamination control activities that occurred inplant, it was not necessary to lay plastic within the ambulanc Both the hospital and the ambulance had been informed by exercise participants in the Simulator that the victim was contaminate The licensee's procedures do not require that an Unusual Event be declared until an ambulance leaves the Protected Area with a contaminated, injured person. By the time that occurred in this scenario, an Alert had already been declared for a simulated reactor coolant pump failur Although an Unusual Event had not been declared for the onsite medical emerger.cy, State and county officials were informed of that situation soon after the ambulance i

had left the plant.

l Based on the above findings, this portion of the licensee's program was acceptable.

l Technical Support Center (TSC)

l The TSC achieved fully operational status about 75 minutes after the i Alert declaration. Assembly and accountability of all onsite

,

personnel was promptly initiated by the Emergency Coordinator (EC)

j after the Site Area Emergency declaration, and was completed within l

the 30 minute goal.

!

The EC and his TSC staff maintained a good awareness of changing plant conditions, the activities of inplant repair teams and current ano forecast meteorological conditions. The EC and his principal aides held several meaningful discussions to set priorities and to L share information on their efforts. Offsite dose assessment l responsibility was transferred to Emergency Operations Facility l (EOF) staff prior to the simulated release. However, TSC dose assessment staff worked in parallel with their E0F counterparts until the release had been terminated.

Beginning at about 7:45 p.m., exercise controllers made the Emergency Response Facility Information System (ERFIS) unavailable to TSC and E0F exercise participants. This computer system is used to provide current plant parameter information and to trend certain types of plant data. The unavailability of ERFIS caused the EC to dispatch a Health Physics technician to the Control Room Simt lator to obtain relevant area radiation monitor dat These data were then periodically reported to TSC staff over the telephon Other TSC staff also had to rely on more frequent conversations with Control Room staff.to obtain updated information on such key plant parameters as containment pressure and radiation level. TSC staff then used telephone lines to relay Jpdated plant parameter data to their E0F counterpart TSC and E0F staff used pre-formatted status boards to display relevant plant parameter data. With the unavailability of ERFIS computer terminals, flip charts or graph paper were primarily used to trend critical containment parameter The pre-formatted status boards were also used in both facilities to display parameter trends by using color-coding to indicate the valid times of several sets of data, or by using arrows to indicate trend However, the display of trended data was more readily visible in the E0F than in the TS Also, the methods utilized to display trended data on pre-formatted status boards varied over time in both facilities, but were somewhat more consistent in the E0 Habitability monitoring was adequately demonstrated in the TS The EC was-kept informed of Operational Support Center habitabilit Administrative support and security were very good in the TS Based on the above findings, this portion of the licensee's program was acceptable; however, the following item should be considered for improvement:

I * To avoid confusion, a more consistent methodology should be-developed fcr prominently displaying several hours of trended plant data on TSC and EOF status board d. Emergency Operations Facilitiy (E0F)

The E0F became fully operational, with the Pecovery Manager (RM) in charge of the licensee's response efforts, approximately one hour after the Site Area Emergency declaration. A General Emergency was correctly classified within another five minute Initial offsite notifications were completed in a timely manner by E0F communicators using a dedicated telephone line to the State's and counties'

Emergency Operations Centers (E0Cs). The RM reviewed approved all initial and periodic followup message forms prior to message transmittal to offsite officials. On at least three occasions during the exercise, the RM personally spoke to offsite officials using the dedicated telephone line to explain the rationale behind the current Protective Action Recommendation (PAR) and to elaborate

.

on current plant conditions, onsite repair activities, and his prognoses for major changes. Periodic staff meetings and facility Public Address (PA) announcements were effectively used within the E0F to share information on changing scenario conditions and response effort Representatives of offsite agencies, located in a room adjacent to the Recovery Center Room, could 1: sten to these PA announcements and could also interface with the E0F's Offsite Liaison Coordinato The initial and upgraded PAR were formulated in accordance with procedures, and were accurately transmitted to State and county officials in a timely manne The RM and several key aides remained adequately aware of what protective actions were being implemented by county official Although a prominent Recovery Center status board had provisions for listing the current PAR and the actions being implemented by offsite officials, the initial. PAR was never written on this status board nor were those protective actions being taken offsit The release began after the revised PAR, which was based on deteriorating plant conditions, had been transmitted to offsite official About ten minutes later, the RM used the dedicated telephone line to. informally brief offsite officials on the suspected release path. He also indicated that the revised PAR was being reevaluated in view of the releas Dose assessment staff correctly concluded that no further PAR changes were warranted. The official mes', age stating that the release had begun was transmitted about 35 r.inutes after the release bega The RM and key staff were kept adequately informed of an inplant team's progress in temporarily blocking the release path, and on other teams' progress in restoring various plant system Dose assessment staff utilized a default release duration value until a bettar engineering estimate of release duration became availabl Once the path had been temporarily blocked, the RM exhibited good conservation in not downgrading the emergency classification. He stated that he wanted to wait until a more permanent seal f0r the release path had been fabricated and installed, and until further investigations had been completed to ensure that no other release paths existed. He also stated that substantial core damage had been estimated and that much offsite survey work needed to be complete For these reasons, the RM correctly saw no purpose in hastily downgrading the emergency classification.

l Following a one day time jump in the scenario, the RM led his key staff in a good, initial compilation of Recovery action item His staff provided a number of good inputs regarding: assessing plant

system's status; determining onsite decontamination needs; addressing j offsite radiological impact; public affaira concerns; and assessing l longer-term staffing requirements. The needs to prioritize these action items and estimate task completion times were also recognize ,

Based on the above findings, thic portion of the licensee's program was acceptable; however, the following item should be considered for improvement:

  • The current PAR and protective measures being implemented offsite should be posted on a status board for quick refere1ce by anyone in the EOF, including any newly arrived Federal, State, county, and license representative . Scenario and Controller = Actions (82301)

The licensee's scenario was submitted in accordance with the established schedule. Clarifications and several corrections to the scenario information were provided in a timely manner. Exercise controllers did a good job in keeping the exercise on scheduled without resorting to contingency messages. No examples of improper controller actions were identified by the inspector Based on the above findings, this portion of the licensee's program was acceptable. However, the scenario also included activation of the Operational Support Center (OSC), inplant maintenance teams, a post-accident sampling team, offsite survey teams, and the Joint Public Information Center (JPIC). While two inspectors briefly observed OSC activities, neither concluded that sufficient time was spent in the facility to meaningfully evaluate player performance. Due to an Emergency Facility Appraisal being conducted concurrently with the exercise inspection and other factors restricting exercise inspection team size, the JPIC and aforementioned inplant and offsite teams were not evaluated during this inspectio . Exit Interview On June 7, 1988, the inspectors met with those licensee representatives identified in Paragraph 1 to present their preliminary inspection findings. The licensee agreed to consider the items discussed and indicated that-none were proprietary in natur Attachments: Exercise Otjectives l Narrative Summary l Timeline l
