Dear Sir:
Pursuant to the telephone conversation between NRC Region IV and the Licensee on 23 August 1988 the following additional information is provided regarding the University of Utah's response, dated 4 August 1938, to Notice of Violation and Deviation, Report 50-407/88 07, 50-0723/88-01, University of Utah Reactors (License R 25: AGN 201, Docket 50 072 and License R 126: TRIGA, Docket 50-407).
Violation 2 (407/880102). In addition to the revised written procedure for insertion and I
removal of heavy water tanks, the Licensee has modified its checkout procedure for operation of the TRIGA reactor (see enclosed form NEL 001, Sheet 1) to require that the Maintenance Log be reviewed for any core operations which might affect reactivity. This action will ensure that the operator is apprised of such changes.
Violation 3 (407/880103). Any component removed from the reactor core which may be radioactive and is not to be immediately placed in a shielded container will be surveyed for contact radiation levels and will be tagged with the maximum radiation reading. The Facility Operations Manual will be revied by September 5,1988 to reflect this practice.
Further, the Radiation Saf:ty Officer has reviewed procedures to ensure that NEL staff are perfornung and documenting such radiation surveys in an acceptable manner.
Sincerely, pk j 4)
