Section 504.50  Updating Station Catalogues and System Status Signals Catalogue

a)         For each point included in the Station Catalogue, the Station Catalogue shall contain, as a minimum, the name of the point; a description of each parameter (point) measured, sensed or calculated; the units of measure for analog points; the state indication for digital points, e.g., open or closed, on or off; and the type of point, e.g., analog or digital.

b)         On the effective date of this Part, the Department will consider the current Station Catalogue for each nuclear power station to be the most recent Station Catalogue that was provided the Department pursuant to the prerulemaking arrangement between the owner and the Department.

c)         The owner shall provide the Department an updated Station Catalogue for each nuclear power station at 180 day intervals.  In the event that the Station Catalogue remained unchanged, the owner shall notify the Department that no changes were made in lieu of providing an updated Station Catalogue.  The end of each 180 day interval shall be consistent with the end of the prerulemaking 180 day interval already in effect for the owner under the prerulemaking arrangement between the owner and the Department.  The Department may lengthen the Station Catalogue submission interval at any time.

d)         Within 14 calendar days after receipt of an updated Station Catalogue, the Department shall provide the owner with notice of any changes to the System Status Signals Catalogue(s).

e)         The Department shall select points for the System Status Signals Catalogue from the updated Station Catalogue using the following criteria:

1)         those points by which the off-site radiological consequences can be determined;

2)         those points by which challenges to, and failures of, the clad, the primary boundary, and the containment structures can be determined;

3)         those points by which short and long-term decay heat removal capabilities can be determined; or

4)         those points by which on and off-site station electrical power status can be determined.
