McDavitt, Emergency Planner J. Randazza, Executive Vice President W. Riethle, Manager, Radiation Protection M. Swartz, Supervisor, Simulator Group P. Thompson, Manager of Public Affairs D. Whittier, Manager, Nuclear Engineering and Licensir:

E. Wojnas, Emergency Planning Engineer The team observed and contacted several I censee personnel prior to and during the exercis .0 Emergen_cy_ Exercise The Maine Yankee Atomic Power Station full participation exercise was conducted on June 22, 1985, from 6:00 A.M. to 1:40 .1 Pre-Exercise Activities Prior to the emergency exercise, NRC Region I representatives had telephone discussions with licensee representatives to review the scope and content of the exercise scenario. As a result, minor revisions were made to the scenario and the supporting data sheet The NRC observers and licensee controllers / observers attended a scenario briefing on June 21, 1985. The changes in the scenario and the emergency response actions expected during the various phases of the scenario were discusse The exercise scenario included the following events:

• Reactor coolant leak;

• Reactor trip;

• Loss of power to charging pumps;

• Equipment hatch failure in cor tainment;

• Reactor core degradation;

• Release of radioactivity; and

• Implementation of the Recovery Organizatio *

.

.

The above events caused the activation of the licensee's emergency facilities and also permitted the state and local government agencies to exercise their Emergency Plan .2 Activities Observed During the conduct of the licensee's exercise, NRC team members made detailed observations of the activation and augmentation of the emergency organization; activation of emergency response facilities; and actions of emergency response personnel during the operation of the emergency response facilities. The following activities were observed:

• Detection, classification, and assessment of the scenario events; i

• Direction and coordination of the emergency response;

• Notification of licensee personnel and offsite agencies of pertinent information;

• Assessment and projection of radiological (dose) data and consideration of protective actions;

• Provisions for in plant radiation protection;

• Perfermance of offsite, onsite, and in plant radiological surveys;

• Maintenance of site security and access control;

• Performanca of technical support;

• Performance of repair and corrective actions;

• Communications /information flow, and record keeping; and

• Management of Recovery Operation .3 Exercise Observations

,

The NRC team noted that the licensee's activation and augmentation of the emergency organization; activation of the emergency response facilities; and actions and use of the facilities were generally consistent with their emergency response plan and implementing procedures. The team also noted the following actions of the licensee emergency response organization that were indicative of their ability to cope with abnormal plant condition * Emergency response personnel appeared generally knowledgeable in performing their duties and maintained an active role in demonstrating assigned functions in accordance with emergency procedure * Control room personnel demonstrated teamwork and effectively used the established Emergency Action Levels for classification of the event *The TSC personnel promptly recognized problems and evaluated events for potential in a manner that demonstrated effective coordination of support activitie ' Staff briefings were timely in each of the emergency facilities, and the team briefings in the OSC were thorough.

• The E0F coordinated the actions of the offsite monitoring teams and routinely informed the teams of plant condition * Habitability surveys of each of the emergency facilities were performed in a timely manne The following areas were identified which require licensee attention:

• (0 pen) 50-309/85-12-01: The PA announcement of the Unusual Event did not include the reason for the classification and the PA announcements for the Site Area and General Emergency classifications included instructions for personnel to take actions that had previously been implemente *(0 pen) 50-309/85-12-02: The Plant Shift Supervisor (PSS) was distracted from directing the Control Room (CR) personnel during lengthy telephone discussions with the Technical Support Center (TSC).

• (0 pen) 50-309/85-12-03: The Control Room did not request the TSC to calculate the leak rate when operators became occupied with cooldow *(0 pen) 50-309/85-12-04: There were no PA announcements relative to who was directing the emergency response force when the PSS was relieve *(0 pen) 50-309/85-12-05: There were no PA announcements to inform emergency response personnel that the E0F, TSC, and OSC were activate *(0 pen) 50-309/85-12-06: The primary dose assessment system does not include estimation of a source term for iodine and there is no methodology provided to estimate the iodine source term for different release pathways nor to estimate the effective filter efficiencies for different removal system This resulted in an inappropriate decision to issue potassium iodide during the exercis *(0 pen) 50-309/85-12-07: The OSC did not track cumulative exposure of corrective action team member The licensee's actions in addressing these items will be reviewed in a subsequent inspectio .0 Licensee Actions On Previously Identified Items (Closed) 50-309/84-21-01 through 84-21-08: The inspectors confirmed that adequate protective actions had been implemented regarding the eight open items identified during the annual emergency exercise conducted on September 19, 1984, and all items are considered closed.
