Dear Mr. Macleod:
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 specification or design envelope for a complete nuclear power plant, either PWR or BWR, with capacities ranging from 500 MWe to 1350 MWe. This document is being written for the nuclear industry by the Electric Power Research Institute. The Requirements Document is now under review by the USNRC staff.
When approved by the NRC, the Requirements Document is intended to be used as a requirements road map for designers of future nuclear power plants. The document will provide the specific plant attributes desired by the nuclear utilities and ourselves for the plants of the 1990's and beyond. Some more important attributes are for example:
Longer plant life
- Increased plant availability
- Reduced core melt frequency Reduced radiation release from severe accidents Increased thermal margin
- More tolerant of operating transients
- Reduced number of unplanned plant trips I am conveying this executive summary to you to keep you abreast of develop-ments and would be most appreciative of any comments you have on the document.
Very truly yours, l n
! Harold R. Denton, Director Office of Nuclear Reactor Regulation 87031103D6 870226 PDR TOPRP EXIEPRI C PDR
