Millstone Nuclear Power Station, Unit No. 2 Environmental Qualification of Class lE Equipment In accordance with the reporting requirements of Reference (1), Northeast Nuclear '

Energy Company (NNECO) informed the NRC Staff in Reference (2) that certain Resistance Temperature Detectors (RTD's) were not qualified for service in the LOCA environment.

Subsequent engineering reviews have substantiated the adequacy of the deference (2) material and as such, the 14-day follow-up report is rendered superfluous.
