..no.. i... um April 3,1992 UFIR Safety Analysis Report Revision 7,4/92 U.S. Nuclear Regulatory Commission Washington, D.C. 20555 Attn: Document Control Desk Re:
University of Florida Training Reactor Facility Ucense: R 56, Docket No. 50-83 Gentlemen:
- The enclosed package contains Revision 7 pages for the UFTR Safety Analysis Report dated January,1981 submitted as part of our relicensing effort. Revision 7 consists of changes to two pages. The revision has resolted from the need to make certain minor changes in the descriptions of the resins used in the primary coolant system demineralizer and makeup water system demineralizer as well as the need to make a change in the secondary cooling system pump. All changes have been reviewed by UFTR management and the UFTR Safety Review Subcommittee and are not considered to involve any unreviewed safety question or to impact the UFTR Safety Analysis as outlined below; all text changes are denoted by vertical lines in the right hand margin of the attached affected replacement pages. Reasons for all text changes are explained in the following paragraphs.
The first change is included on Page 5 8 to allow the use of an equivalent deep well pump per the slightly changed description in Section 5.2 describing the UFTR Secondny Cooling System. This change to a more efficient. pump was necessitated by the failure of the previous pump in February,1992 and the unavailability of an exact replacement; it was evaluated and determined not to involve any unreviewed safety questions per 10 CFR 50.59 Number 92-01.
The second change is included on Page 9-6 because the Amberlite IRN 150, nuclear-grade resins specified for use in the Demineralized Water Makeup System and the primary coolant.
Purification System are no longer available. These systems were converted to utilizing equivalent Purolite NRW-37 resins in January,1991; however, the changes in Section 9.2.3 and Section 9.2.4 are included to allow the use of any equivalent resin. In this way any future substitution can be made following an in-house evaluation of equivalency. This change was evaluated and determined not to involve any unreviewed safety question per 10 CFR 50.59 Number 91-01, i '. P. U '

The changes simply update the SAR.
The entire enclosure consists of one(1) signed originalletter of transmittal with enclosure plus ten (10) copies of the entire package. If further infortnation is required, please advise.
