Period??



I believe the technical basis NRC and FEMA are using for the fast breaker

comes from NUREG-0396/EPA-5201-78-016, "Planning Basis for the Development

of State an Local Government Radiological Emergency Response Plans in

Support of Light Water Nuclear Power Plants." Section III.C addresses

"Time Factors Associated with Releases." These times come from the Reactor

Safety Study (a.k.a. WASH-1400), and say that major releases may being in

the range of one-half hour after an initiating event. This leads to the

Appendix E criteria of 15 minutes for the plant to notify the ORO, and

about 15 minutes then for the ORO to warn the public. To date the NRC has

allowed the use of the Alternative Source Term (NUREG-1465) for Design

Basis Accident Analysis (64 FR 72001, Dec. 23, 1999), including changes

based on the timing of releases, but not for Emergency Plan changes.
