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)
