"Loss of Fill-Oil in Transmitters Hanufactured by Rosemount,"
was issued by the NRC on December 22, 1992, to inform addressees of activities taken by the NRC staff and the industry in evaluating Rosemount transmitters and to request licensees to take actions to resolve this issue.
Supplement 1 requests utilities to review the information for applicability to their facilities, perform testing on the transmitter comnensurate with its importance to safety and demonstrated failure rate, and modify as appropriate, their actions and enhanced surveillance programs.
Supplement 1 also requested that licensees provide a response that included a
statement as to whether or not the licensee will take the actions requested, a
list of specific actions that the licensee would complete, and the schedule for completing the actions.
Additionally, when the specific actions committed to in the licensee's response were completed, the licensee was required to provide a statement confirming said completion.
If the licensee did not plan to comply with all of the Requested Actions as delineated in Supplement 1,
a statement was required identifying those Requested Actions not taken, as well as an evaluation which provided the bases for Requested Actions not taken.

In the Harch 8, 1993, letter, NHPC committed to transmitter replacement during the refueling outage scheduled for September
- 1993, and implementation of enhanced monitoring by Hay 1, 1993.
By letter dated December 14,
- 1994, NHPC stated that the actions committed to in their Harch 8, 1993, letter had been completed.
A detailed evaluation of the licensees response is documented in the enclosed Technical Evaluation Report (EGG-DNSP-10919, September 1994).
Me have reviewed NHPC's response to NRC Bulletin 90-01, Supplement 1,
and conclude that NHPC conforms to the Requested Actions of NRC Bulletin 90-01, Supplement 1,
and has completed the reporting requirements.
Compliance with applicable Commission requirements may be the subject of NRC audits or inspections in the future.
