Dear Mr. Eisenhut:
Three Mile Island Nuclear Station, Unit I ('IMI-1)
Operating License No. DPR-50 Docket No. 50-289 Safety Parameter Display System NUREG 0737 (Iten I.D.2)
Enclosed you will find GPUN Topical Report #18 entitled TMI-l Safety Parameter Display Systen (SPDS) Safety Analysis. As we Indicated in previous letters, GPUN cmmitted to provide the NRC with this SPDS Safety Analysis by April 30, 1984 in acmrdan with the requirenents of NUREG 0737 Supplement 1, (Generic Ietter 82-33).
In our letter of February 1,1983 we describe the status of the SPDS as a subset of the Plant Ctmputer System. The TMI-l SPDS will be available in a " basic" form by January 1,1985. The " basic" SPDS is that portion of the final SPDS which is a subset of the 2500 points currently available in the computer data base.
These parameters are identified by Note 3 in Table 3.1.
This report identifies those Critical Safety Functions (CSFs) that describe the safety status of the plant. The analysis also indicates the additional instrumentation /paraneters that require incorporation into the existing plant cxxnputer data base. The SPLS parameters will alert the user through warnings or alanus of abnormal conditions and will be tested (analytically) against a range of transients / accidents to determine if each event in a transient can be nonitored and evaluated adequately.
Sincerely, 0405040276 840430 PDR ADOCK 05000289
