. DISCUSSION AND NO SIGNIFICANT 11AZARDS ANALYSIS By letter dated March 23, 1988, a Technical Specification amendment was requested which would place controls on the equipment associated with the Monitor Tank Building which is being constructed on the Catawba site. The proposed amendment was reviewed and subsequently issued on April 26, 1988.

This amendment request would add a footnote to Tabic 4.3-8, Table Notation 1 and Table 4.3-9, Table Notation 2. This amendment would also change a reference on Table 4.11-1. Currently radiation monitor EMF-58 is referenced under Liquid Release Type, item 1. This monitor (EMF-58) is the gaseous release monitor. The liquid release monitor which should be referenced on Table 4.11-1 is EMF-57.

The footnotes to be added to Tables 4.3-8 and 4.3-9 would clarify that the alarm annunciators for EMF-57 and EMF-58 alarm in the Monitor Tank Building (MTB)

> Control Room and r'.so on the remote MTB control panel which is located in the Auxiliary Building. This is in accordance with t'no design of this system as described in the March 23, 1988 submittal.

10 CFR 50.92 states that a proposed amendment involves no significant hazards considerations if operation in accordance with the proposed amendment would nots (1) Involve a significant increase in the probability or consequences of an accident previously evaluated: or l

1 (2) Create the possibility of a new or different kind of '

accident from any accident previously evaluatedt or (3) Involve a significant reduction in a margin of safety.

The proposed amendment does not involve an increase in the probability or co:. sequences of any previously evaluated accident. The previously evaluated accidents are not affected since these changes are to add clarification and to correct a reference to a monitor. As such, these changes are administrative and have no impact on the design or operation of the station.

J .

l The proposed a wndment does not create the possibility of a new or different kind l

of accident from any accident previously evaluated. Since the changes requested are administrative in natura, no new modes of operation are introduced. The design and operation of the facility will not be affected by this amendment.

The proposed amendment does not involve a significant reduction in a margin of safety. Since these changes are administrative in nature, the nargin of safety will not be affected. 1 For the above reasons, Duke Power concludes that this proposed aciendment does not involve any Significant Hazards Considerations.
