EXERCISE WEAKNESSES

1. The NRC was not notified within one hour after the Site Area Emergency

was declared as required by 10 CFR 50.72(a)(3). This notification was

not initiated until four hours and 47 minutes after the declaration Site

Area Emergency.

In addition,- the NRC was not notified of any major change of emergency

events throughout the exercise. These omissions included an uncontrolled

release of radioactivity and issuance of two protective action

recommendations (PARS). (Section 5.a) (454/86013-01, 455/86011-01)

2. The Emergency Operations. Facility (EOF) did not consider evacuation time

estimates when making the second and final PAR for the public within the

10 mile Emergency Planning Zone (EPZ). This was contrary to Emergency

Implementing Procedure BZP 300-AZ, Recommended Protective Actions for

Actual or Imminent Gaseous Release Conditions.

Also, this PAR was issued approximately eight minutes after an

uncontrolled release took place at 1400 and included 0-2 mile radius

evacuation. This recommendation could have endangered residents who would

have been evacuated through the plume. (Section 5.d) (454/86013-02,

455/86011-02)
