- 1977, submitted the details of:
(1) proposed design modifications for protection against sustained undervoltage conditions and the associated test circuitry; (2) proposed changes to the Technical Specifications associated with the above mentioned design modifications for the Nine Mile Point, Unit 1.
By letter dated March 5, 1984, you informed us that modifications in addition to those proposed in July 15, 1977 and later implemented, would be performed to the existing diesel generation setpoint logic during the Spring 1984 (current) refueling outage.
- Further, you informed us that the ongoing modification requires a revision to the July 15, 1977 application and that the revised application would be submitted on April 1, 1984.
We have completed our review of your July 15, 1977 submittal and conclude that the design modifications in that submittal comply with our requirements and are, therefore, acceptable.
We will act on your expected Technical Specification submittal of April 1, 1984 as a separate licensing action.
