I CONDUCT of EXERCISE SCOPE nnd PARIlfTANTS (cont)

SCOPE As an assurance that the health and safety of the general public is protected in the event of an accident at the Fort Calhoun Station (FCS), the Omaha Public Power District (OPPD) conducts an annua. emergency preparedness exercise. Exercises simulate accident conditions and radiological hazards that require major portions of utility, state and local emergency response plans and procedures to be implemented. Emergency responses are evaluated by all participants, and the Nuclar Regulatory Commission. Exercise accident sequences, and the severity and characteristics of radiological hazards are held in confidence prior to conducting the exercise.

The -xercise scenario is sufficient to require complete activation of the OPPD emerger.cy response organization for accident mitigation. The accident scenario will require evaluation and decision making on protective actions for the general public surrounding FCS. Additionally, requirements for an annual communications drill between the utility and states are included in the exercise.

Evaluations of the emergency response to situations presented by the exercise scenario help provide an assessment of the adequacy of utility, state and local radiological emergen.m gb .

and procedures. In addition, conduct of the exercise is valuable in determining whether aoer de resources, and trained personnel assigned emergency response responsibilities are available to protect the health and safety of the general public in the event of an emergency at FCS.

PARTICIPANTS The following utility, state and local emergency response facilities and service agencies will participate in 1992 exercise activities.

. l CONDUCT of EXERCISE OILIECTIVES l

Exercise objectives are provided under this heading. Objectives provide a basis for scenario development and a means to evaluate responses by the emergency response organization.

The Omaha Public Power District rr g gica'l emergency preparedness exercise objectives for the Fort Calhoun Station are based on .iuclear Regulatory Commission (NRC) requirements provided in 10CFR50.47, " Emergency Plans", and 10CFR50, Appendix E, " Emergency Planning and Preparedness for Production and Utilization Facilities". Additional guidance provided in NUREG-0654/ FEMA-REP-1, Revision 1, " Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants", was utilized in developing the objectives.

Objectives are grouped according to functional area of emergency response. Additit "" ,  ;

objectives have been cross referenced to major or parent Emergency Plan implementing l Procedures used in demonstrating the objective, and to any related open weaknesses from prior l exercises.

9 CONDUCT of EXERCISE OIMECTIVES (cont) 1991 Exercise Weakness Summary Operations Support Centu 285/9108-01 Complete habitability surveys, including contamination smears were not performed routinely in the Operations Support Center during an approximate two hour period following indications of core damage and subsequent release to the environs. Even though announcemenu were made to prevent eating, drinking and smoking, contamination smears were not conducted between 1200 and 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> to validate habitability requirements of the OSC. Fuure to exercise proper radiological controls in the OSC was identified as an exercise weakness.

Emergency Operations Facility 285/9108-02 There was one instance of field monitoring teams using an older map containing obsolete information. The use of maps containing obsolete information to describe a 'ic!d team's location is considered an exercise weakness. This weakness was corrected by the licensee and closed in NRC Inspection Report 92-08, 285/910b-03 Failure to accurately detect, assess, and correlate plant conditions with radiological releases and dose assessment functions was identified as an exercise weakness.

Although the containment purge line was correctly assumed as the release path due to increasing stack radiation monitor readings, efforts to determine the flow specifics needed for accurate dose projections were ineffective. As a consequence, overly conservative assumptions were used yielding higher than actual dose projections.

I Contributing factors to this weakness included:

l a) Inadequate damage assessment following a simulated short circuit in panel AI-44. This delayed assessment resulted in approximately 40 minutes passing before validation that containment isolation valves PCV-712-C and PCV-742-D had opened as a result of the short.

n CONDUCT of EXERCISE DJ)JECIEES (cont) b) Failure to properly identify stack flow rate via available indications in the Control Room. A general determination was made in several locations that since no auxiliary building fans were operating, stack flow was zero.

This forced the Dose Assessment Specialist in the EOF to perform dose assessment using conservative estimated flow rates. This dose assessment resulted in overly conservative projections.

c) Lack of stack flow rate data on the Emergency Response Facility Computer System (ERFCS), which would allow dose assessment personnel in the TSC and EOF direct access to current data, eliminating a communication link, d) in that conservative stack flow was utilized, several refinements to the release rates used within the EAGLE system were made based on manipulating the dose program to match known field team survey results.

However, these results were accurate only within an order of magnitude.

A formalized method to use EAGLE to incorporate field data and provide "back calculations" of release rates and/or source terms would provide this function in a more timely and consistent mannt.r.
