Subject:
Request for Change to Section 6.2 of the Technical Specifications, Docket No. 50-1S4.
i The National Institute of Standards and Technology respectfully requests a minor change to l Section 6.2 of the design descriptions of the NBSR Technical Specincations. The requested change involves deleting description referring to the number and type of heat exchangers used l in the primary cooling system. NIST believes that the inclusion of this detailed language is unnecessary and may be counterproductive. it limits NIST's capability to obtain the best and most suitable heat exchangers using the latest technology. NIST's basic objective is to obtain units for future replacement that provide maximum assurance of both zero leakage and long term reliability. Such units may be plate type rather than tube and shell type and may be of a different size which could offer signincant improvement in reliability for NBSR application.
The basic design specifications for any type heat exchangers remain exactly the same. -These include material, design pressure and temperature and fabrication code requirements.
Furthermore perforannec specifications are unaffected, including those contained in Limiting Conditions for Opciadon. These conditions already in the Technical Specincations fully satisfy the basis o any intended design description requirements. NIST believes that the requested change ' vill enhance overall operational quality and reliability and thus enhance ,
overall safety.
Accordingly, NIST respectfully requests that the words "one or two, shell and tube," and the word " tubes" be deleted from Section 6.2 of the Technical Specincations and the word "two" before heat exchangers be deleted from the basis.
Sincerely, .
