APPENDIX 18.1<br />

Review Procedures<br />

The reviewer should compare any changed environmental interactions between the<br />

converted LEU facility and the existing HE faciity. The reviewer should<br />

evaluate the discussions in the licensee's submittal about any changed interactions<br />

vith characteristics of the site, either in kind or in magnitude, that results from the<br />

fuel conversion. The conversion of the reactor should not change the conclusions<br />

about the suitability of the site for operation of the reactor with the LEU fuel.<br />

Changes in the impact on site characteristics due to conversion may be<br />

compensated for by changes in facility design which should be listed and<br />

referenced to applicable sections of the SARI<br />

Evauafion Findngs<br />

This section of the SAR should contain sufficient information to support one of the<br />

following types of conclusions, which will be included in the staffs safety<br />

evaluation report:<br />

* The site characteristics and associated environmental hazards will not be<br />

significantly changed by the reactor conversion, so there will be' no<br />

decrease in the suitability of the present site for continued operation of the<br />

reactor. The conclusions of site suitability reached in the SAR and the<br />

safety evaluation report for the HEU operating license remain valid for the ><br />

LEU-fueled reactor, as proposed.<br />

* The impact on the site characteristics and associated environmental hazards<br />

due to conversion have been identified. Faclity-structures, systems, and<br />

components have been analyzed in subsequent sections of the safety<br />

analysis to demonstrate acceptable design to compensate for changes in site<br />

inpact.<br />

3 DESIGN OF STRUCTURES, SYSTEMS, AND<br />

COMPONENTS<br />

Areas of Review<br />

This section of the SAR should contain information on the design bases of faicility<br />

structures, systems, and components, and a discussion of any modifications in the<br />

design bases for the BEU to LEU conversion; This section should reference all<br />

significant standards and guides applicable to the conversion, including rules and<br />

regulations, siaff reports (<strong>NUREG</strong>s), regulatory guides, and the American<br />

National Standards Institute/American Nuclear Society (ANSI/ANS) standards<br />

used to design all proposed modifications to the reactor facility. This section<br />
