Dear Mr. Diar:

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 4

. . Feduced radiation release from severe accidents

  • 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.

V py truly yours, l 4
