Subject:

Catawba Nuclear Station Dockets 50-413 and 50-414 Operator Aid Computer (OAC) Replacement Link to NRC Emergency Response Data System (ERDS)

Request for Additional Information l

l In a letter dated June 3, 1996 letter, Duke. informed the NRC of l plans to replace the OAC at Catawba Nuclear Station, Unit 1 and of the impact of this OAC replacement on the Unit 1 link to the NRC ERDS. A revised data point library was submitted as an

. attachment to that letter. ,

By letter - dated July 15, 1996, from Frank J. Congel of your staff, five areas were identified where ' additional information l was required in order to provide physical significance to the ERDS data for use by NRC technical teams. Catawba's response to those questions is attached.

If there are any questions concerning this . response, please

! contact Kay Nicholson'at (803) 831-3237.
