Director, Office of Nuclear Reactor Regulation Attention:
Mr. George W. Knighton, Branch Chief Licensing Branch No. 3 U. S. Nuclear Regulatory Commission 3
Washington, D.C.
20555 Gentlemen:
Subject:
Docket Nos. 50-361 and 50-362 San Onofre Nuclear Generating Station (SONGS)
Units 2 and 3 The purpose of. this letter is to comply with the requirements of 10 CFR 50.49(g).
The enclosure identifies electrical equipment important to safety that are either environmentally qualified or in the process of being qualified. All equipment except the auxiliary feedwater pump motors neet NUREG-0588 guidelines for a Category II plant (IEEE 323-1971 standard).
However, some equipment will not be assigned a qualified life until additional t' sting has been completed.
The updated status of outstanding items is as follows:
1.
Rosemount Transmitters Foxboro Transmitters These transmiters all have qJalification documentation available i
which meet IEEE 323-1971 requirements.
Since SONGS 283 are l
Category II plants, this complies with HUREG-0588 requirements.
T..e qualification documentation, however, is based on the testing of unaged components and, with the exception of the Rosemount transmitters, separate effects testing methods were used in the qualification process.
In order to improve the qualification of the transmitters and to establish a reasonable qualified life, SCE has joined with other utilities to qualify the transmitt_ers to IEEE 323-1974 specifications.
Full qualification of the transmitters to IEE 323-1974 specifications will be completed prior to March 31, l
1985.

Auxiliary Feedwater Pump Motors The auxiliary feedwater pump motors containing replacement bearings made from cast iron were environmentally qualified for a harsh environment. Due to bearing failures in June,1982 the cast iron bearings were replaced with the originally equipped babbitt bearings. Auxiliary feedwater pump motor environmental qualification was addressed by separate correspondence in the March 7,1983 letter from SCE (K. P. Baskin) to the NRC (G. W. Knighton). The schedule for qualification of this equipment is dependent on NRC acceptance of the proposed hardware modification described in the referenced letter.
If you have any questions or comments, please contact me.
