MEMORANDUM FOR: Themis P. Speis, Director Division of Safety Review and Oversight '"
Denwood F. Ross, Acting Director Office of Nuclear Regulatory Research FROM: Robert M. Bernero, Director
_ Division of BWR Licensing .
SUBJECT:
GENERIC REQUIREMENTS FOR BWR CONTAINMENT RESPONSE TO SEVERE ., ' .
ACCIDENTS -
Attached is the current proposed chronology of actions related to BWR ' -
containment enhancement. The effort has reached a point where I feel.that a meeting to discuss the containment response portion of the Peach Bottom study supporting the forthcoming NUREG-1150 will be very important to assure a consistent NRC thinking on BWR containment performance modeling. '
I request that a meeting be arranged for mid October in which NUREG-1150 '
contributors can present and discuss their current analyses and potential conclusions with NRC staff and supporting consultants.
