  • Attended exit interview

2. Exit Interview

The inspection scope and findings were summarized on September 11, 1987,

with those persons indicated in Paragraph I above. The inspector

described the areas inspected and discussed in detail the inspection

findings. Major emphasis was directed toward the findings identified in

Paragraph 7.. The inspector further discussed these items with licensee

representatives via telephone on September 16, 1987. The licensee did not

identify as proprietary any of the materials provided to or reviewed by

the inspectors during this inspection.

3. ExerciseScenario(82301)

The scenario for the emergency exercise was reviewed to assure that

provisions were made to test the integrated capability and a major portion

of the basic elements defined in the licensee's Emergency Plan and

organization pursuant to 10 CFR 50.47(b)(14), Paragraph IV.F of Appendix E

to 10 CFR 50, and specific guidance promulgated in Section II.N of

'

NUREG-0654.

The scenario was reviewed and discussed with licensee representatives in

,

advance of the scheduled exercise date. Scenario problems identified

l during the review were discussed with the licensee, i.e., the finding that

'

some areas required additional data to improve exercise control. Both NRC

L evaluators and licensee controllers noted the need for additional dose

rane information to augment the health physics control of the exercise.

'

The scenario provided information to the States, counties, local

government and federal agencies consistent with their participation in the '

exercise.

The controllers provided adequate guidance throughout the exercise. The

inspectors observed neither prompting nor undue interaction between

controllers and players. The scope and objectives of the exercise were

'

satisfied.

No violations or devietions were identified, j

10 CFR 50.47(b)(1), Paragraph IV. A of Appendix E to 10 J n 50, and

specific guidance promulgated in Section II.A of NUREG-0654. ]

The inspectors observed that specific emergency assignments were made for

the licensee's emergency response organization, and that adequate staff

was available to respond to the simulated emergency. The initial response

organization was augmented by designated licensee representatives;

however, because of the scenario scope and conditions, long term or

continuous staffing of the emergency response organization was not

requi red. Discussions with licensee representatives and detailed review

of the site Radiological Emergency Plan indicated that a sufficient number

of trained technical personnel were available for continuous staffing of

the augmented emergency organization, if needed.

The inspectors also observed activation, staffing, and operation of the

emergency organization in the Technical Support Center (TSC) and

Operations Support Center (OSC). . In accordance with the scope and

objectives of the scenario, activation of the Emergency Operations

Facility (E0F) was accomplished the previous day during an EOF activation

drill . The arrival of Corporate Response Organization personnel was timed

to simulate actual response time.

The scenario developed for this exercise exercised the onsite emergency l

organization.

The scenario developed for this exercise was an uncomplicated reactor

coolant leak in the containment which progressed from a small to large

leak rate. The casualty unit was operating with 1% failed fuel. A leak

path from the containment through a post-accident venting system exhaust

line was postulated to provide protective action decisionmaking and

provide a source term for dose assessment and Radiation Monitoring Teams.

l- -The exercise began at'7:00 a.m. on September 10, 1987. The E0F and News

l Media Center (NMC) corporate players were pre-staged in a classroom of the

E Training Center and instructed to arrive at the E0F and NMC at 9:30 a.m.

The _E0F and NMC setups were accomplished during a previous day's drill for

.those facilities.

The lack of a challenging scenario made it difficult to assess the

adequacy of the 9mergency organization in responding to a casualty that

was neither time demanding and/or event demanding. However, the scenario

was adequate to address the limited objectives the licensee had

established..

No violations or deviations were identified.

5. Onsite Emergency Organization (82301)

The licensee's-offsite emergency organization was observed to assure that

the following requirements were implemented pursuant to

10CFR50.47(b)(2), Paragraph IV. A of ' Appendix E to 10 CFR 50, and

specific guidance' promulgated in Section II.B of NUREG-0654:

(1) unambiguous definition of responsibilities for emergency response; (2)

provision of adequate staffing to assure initial facility accident

response in key functional areas at all times; and (3) specification of '

onsite and offsite support 7 organizational interactions.

The inspectors observed that the initial onsite emergency organization was

adequately defined and 'that staff was available to fill key functional

positions within the organization. Augmentation of the initial emergency

response organization was accomplished through mobilization of off-shift

personnel. The on-duty Shift Supervisor assumed the duties of Emergency

Coordinator upon inniation of the simulated emergency, and directed the

response until formally relieved by the Assistant Regional Nanager, ,

Operations. Required interactions between the licensee's emergency '

response organization and State and local support agencies were adequate

and consistent with the scope of the exercise.

No violations or deviations were identified.

6. Emergency Classification System (82301)

This area was observed to assure that a standard emergency classification

and action level scheme was in use by the nuclear facility licensee

pursuant to 10 CFR 50.47(b)(4), Paragraph IV.C of Appendix E to 10 CFR 50,

specific guidance promulgated in Section II.D of NUREG-0654, and guidance

reconnended in IE Information Notice 83-28.

An Emergency Action Level matrix was used to identify and properly

-classify an emergency, and escalate it to more severe emergency

classifications as the simulated accident sequence progressed. Licensee

actions in this area were timely and effective.

Observations confirmed that the emergency classification system was

effectively used and was consistent with the Radiological Emergency Plan

and Implementing Procedures. The system was observed to be adequate for

classification of the simulated accident sequences. The emergency

procedures provided for initial and continuing mitigating actions during

the simulated ~ emergency.

No violations or deviations were identified.  :

7. ' Notification Methods and Procedures (82301)

This area was observed to assure that procedures were established for

-notification of State and local response organizations and emergency

personnel by the licensee, and that the content of initial and followup

messages to response organizations were established. This area was

further observed to assure that means to provide early notification to the

populace within the plume exposure pathway were established pursuant to

10CFR50.47(b)(5), Paragraph IV.D of Appendix E to 10 CFR 50, and

specific guidance promulgated in Section II.E of NUREG-0654.

An inspector observed that notification methods and procedures were

established and available for use in providing information regarding the

simulated emergency conditions to Federal, State, and local response-  !

organizations, and to alert the licensee's augmented emergency response

organizations, if required. Notification of the States of Alabama and

Georgia and other designated offsite response organizations was completed.

Timely followup notification messages were made and hard copies

appropriately distributed. It was observed however, that both Central

Daylight Savings Time (CDST) and Central Standard Time (CST) appeared on

the Followup Message / Periodic Update Message Form. The computer generated

time was operating on CST and the drill personnel on CDST.

Inspector Followup Item 50-348/87-20-01, 50-364/87-20-01, Failure to use a )

Inspection disclosed that completion of the initial notification at the l

Alert declaration notification was delayed beyond 15 minutes

(approximately 24 minutes) due to the incorrect contact of the Alabama

Emergency Management Agency instead of the Alabama Bureau of Radiological

Health as required by Procedure FNP-0-EIP-26, "Offsite Notification." At

the Site Area Emergency and General Emergency declaration the licensee

failed to use the Initial Notification Message Form as required by

Procedure FNP-0-EIP-18 " Site Area Emergency," and FNP-0-EIP-19, " General

Emergency."

No sioiations or deviations were identified.

8. Emergency Facilities and Equipment (82301)

This area was observed to assure that adequate emergency facilities and

equipment to support an emergency response were provided and maintained

pursuant to 10 CFR 50.47(b)(8), Paragraph IV.E of Appendix E to 10 CFR 50,

and specific criteria defined in Section II.H of NUREG-0654.

The inspectors observed the activation, staffing, and operation of the

emergency response facilities, and evaluated the equipment provided for

emergency use during the exercise.

a. Control Room - The inspector observed that following review and

analysis of the sequence of accident events, Control Room operations

personnel acted promptly to initiate required responses to "'e

simulated emergency. Emergency procedures were readily available, ,

routinely followed, and factored into accident assessment and j

mitigation exercises.

)

Control Room personnel involvement was essentially limited to those

personnel assigned routine and special operational duties. Effective

management of personnel gaining access to the Control Room precluded

. overcrowding, and maintained an ambient noise level required for "

orderly conduct of operations under emergency conditions. .

The Shift Supervisor and the Control Room operators were cognizant of

their duties, responsibilities, and authorities. Control Room

personnel demonstrated an understanding of the emergency l

classification system and the proficient use of specific procedures I

to determine and declare the proper emergency classification.

1

It was observed that data and information provided as the scenario's j

initial sequence of accident events and conditions were readily

'

interpreted by the Control Room staff and factored into commencing  ;

the exercise in a timely manner. The Control Room staff demonstrated l

the capability to effectively assess the initial conditions and l

implement required mitigating actions. l

l

The Control Room notification message associated with the Alert i

Classification is discussed in Paragraph 7 above.

]

b. Technical Support Center - The TSC was activated and promptly staffed

following notification by the Emergency Director of the simulated

emergency conditions leading to the Alert classification. The

facility staff appeared to be cognizant of their emergency duties,

authorities, and responsibilities. Required operations at the

facility proceeded in an orderly manner. This facility was provided

with adequate equipment for support of the assigned staff. TSC

security was promptly established. Radiological habitability was

mnnitored during the exercise. Dedicated communicators were assigned

to the TSC and required notifications were implemented. See

Paragraph 7 above.

The TSC staff identified, classified and declared the Site Area and

General Emergency. Notification of State, Federal and local agencies

was readily completed within 15 minutes. Protective action

recommendations to the State were consistent with the EAL matrix and

guidance promulgated in IE Notice 83-28. It was noted that the

Emergency Director failed to maintain a log of facility activities

throughout the exercise.

Inspector Followup Item'50-348/87-20-03, 50-364/87-20-03, Failure to

maintain an Emergency Director log of important activities.

'

The Emergency Director moved about the TSC discussing plant data and

information and occasionally went to the Control Room to gather and

evaluate pertinent plant data. During those times he failed to

designate a person to be in charge during his absence.

Inspector Followup Item 50-348/87-20-04, 50-364/87-20-04, Failure to

designate a person in charge when the Emergency Director left the

TSC.

c. Operations Support Center - The OSC was promptly staffed following

activation of the emergency plan by the Emergency Coordinator. An

inspector observed that teams were promptly assembled, briefed, and

dispatched.

d. Emergency Operations Facility -

Consistent with the exercise

objectives, the E0F was staffed and activated following declaration

of the General Emergency. The Emergency Director demonstrated

management and control of the facility. Af ter declaring the E0F

staffed and operational, communications between the E0F and TSC were

maintained. Exchange of technical information and frequent

consultation with the TSC were implemented by the staff.

Dose assessment and projections were performed. The dose assessment

group demonstrated proficiency in both manual and computerized dose

assessment. Close contact between assessment groups in the E0F and

TSC were maintained.

Status boards were strategically located to facilitate viewing by the

E0F staff. Status boards were updated as required to chronicle

changes in plant status, accident assessment and mitigation

throughout the exercise. The inspectors noted that a status board

dedicated to trending of simulated plant systems status and

engineering data was maintained and updated during the accident

sequence.

The EOF security was established during facility activation and was

maintained throughout the exercise. Inspection disclosed that

security was confined to a single entrance to the facility, while

additional entrance / exits were unattended.

No violations or deviations were identified  !

9. 'AccidentAssessment(82301)

l

Thin area was observed to assure that adequate methods, systems, and

equipment for assessing and monitoring actual or potential offsite

consequences of a radiological emergency condition were in use as required

by 10 CFR 50.47(b)(9), Paragraph IV.B of Appendix E to 10 CFR 50, and

specific criteria in Section II.I of NUREG-0654.

1

The accident assessment program included an engineering assessment of

plant status, and an assessment of radiological hazards to onsite and

offsite personnel resulting from the accident.

Offsite radiological monitoring teams were dispatched to determine the

level of radioactivity in those areas within the influence of the plume.

Radiological effluent data was received in the TSC and E0F.

!

No violations or deviations were identified. j

10. ProtectiveResponse(82301)

This area was observed to determine that guidelines for protective

actions, consistent with federal guidance, were developad and in place,

and protective actions for emergency workers, including evacuation of ,

non-essential were implemented promptly pursuant to

10 CFR 50.47(b) personnel,(10) and specific criteria promulgated in Section II.J of!

NUREG-0654.

l

The protective measures decisionmaking process was observed by the

hispectors. Recommendations implemented by the TSC staff were timely.

No violations or deviations were identified. I

11. Radiological Exposure Control (82301) l

This area was observed to determine that methods for controlling

radiological exposures in an emergency were established and implemented  ;

for emergency workers, and that these methods included exposure guidelines l

consistent with EPA recommendations pursuant to 10 CFR 50.47(b)(11), and j

specific criteria defined in Section II.K of NUREG-0654.  !

!

An inspector noted that radiological exposures were controlled throughout I

the exercise by issuing supplemental dosimeters to emergency workers and {

by conducting periodic radiological surveys in the emergency response j

facilities. Exposure guidelines were in place for various categories of j

emergency actions, and adequate protective clothing and respiratory

protection was available and used as appropriate.

Dosimetry was available and appropriately used. High range dosimeters '

were also available in case they were needed.

No violations or deviations were identified.

12. Exercise Critique (82301)

The licensee's critique of the emergency exercise was observed to

determine that deficiencies and improvements identified during the

exercise, were brought to the attention of management and documented for

corrective action pursuant to 10 CFR 50.47(b)(14), Paragraph IV.F of

Appendi). E to.10 CFR 50, and specific criteria promulgated in Section II.N

of NUREG-0654.

A formal critique was held on September 11, 1987, with exercise

controllers and observers, licensee management, and NRC representatives.

Findings identified during the exercise and plans for corrective action

were discussed. One licensee identified findings involved the difficulty

associated with obtaining an air iodine sample using silver zeolite I

cartridges. Pumps used to sample air could not obtain the procedure

required sample flow volume. Other different equipment problems

associated with Radiological Monitoring teams have been identified during

previous exercise critiques.

Inspector Followup Item 50-348/87-20-05, 50-364/87-20-05, Failure of j

Radiological Monitoring Team equipment to function as required by

Procedure FNP-0-EIP-4.

Licensee action on identified findings will be reviewed during subsequent

inspections. The licensee's critique was detailed, and addressed both

substantive deficiencies and indicated improvement items. The conduct and

content of the critique was consistent with regulatory requirements and

guidance cited above.

No violations or deviations were identified.

The exercise begins at approximately 0700 with a Unit I Reactor.

)

i Coolant System (RCS) leak that will ramp to 70 gpn over the next  !

l

hour. We leak will require a plant shutdown in accordance with I

leakage, technical specifications. I

By approximately 0755 'an Alert should be declared due to RCS leakage.

We leakage will remain at 70 gpm until 0845 at which time the

leakage increases to approximately 1200 gpm which causes a reactor

trip and". safety injection. Approximately 15 minutes later, the

leak develops into a massive rupture resulting in approximately

an 8000 gpm leak path.

By approximately 0910 a Site Area Emergency should be declared due

to the major loss of primary coolant.

At 0945 a leak path will develop out of containment through the (,3;r F1

postaccident venting system exhaust line. Radiation monitoring

teams will be dispatched to determine off-site dose and a d, [/I ,

determination of protective action will be made. A re-entry should .j

be organized to isolate the leak path. Trouble shooting and repair L,g

of the leak path will be allowed to progress up until the point Ipp

.

of actual isolation, but for drill purposes, the isolation process

will be stopped just short of isolation. his drill intervention is f)

necessary to ensure the RMTs have sufficient time to acceeplish all

objectives. ,

i

After the leak path develops out of containment,'the Emergency-

Director may conservatively declare a General-Emergency based on the

criteria of the. loss ~of 2 out of 3 fission product barriers with

a potential loss of the third.

We exercise will be terminated once the RMTs have tracked the

plume, collected samples of water, soil, vegetation, and air

(radiological monitoring drill), the EOF has been staffed and

is performing EDr activities, and the News Media Center staff

has conducted a press conference.
