Dear Mr. Diar:
s s
I am pleased to transmit for your information an Executive Summary of the United States Advanced Light Water Reactor Requirements Document (ALWR).
The ALWR Requirements Document is a performance specificatiol] or design envelope for a complete nuclear power plant, either PWR or BWR, with capacities ranging from 500 MWe to 1350 We.
This document to being written for the nuclear industry j
r.y the Electric Power Research Institute. The Requirements Document is now
~
~ '
under revie o y the USNRC staff.
_; Nhen uoproved ~oy the NRC, the Requirtiments Document is intended to be used as a requirerrents road map for designers of future nuclear power plants. The
, documeM. will provMe the specific plant attributes desired by the nuclear utilities and oursd ves for the plants of the 1990's and beyond.
Some more
' impsrtant attributel, are for exampic.
Longer plant lify Increased plant availability Reduced core melt frequency Feduced radiation release from severe accidents 4
Increased thernal margin More tolerant of operating transients l
Reduced number of unplanned plant trips I am conveying this executive summary to you to keep you abreast of develop-ments and would 'De most appreciative of any comments you have on the document.
