NRC Letter from W. J. Cahill Jr. to Mr. John R. Jolicouer NRC dated REF:
September 20, 1990 and logged TXX-90328.
Gentlemen:
By this letter TU Electric complies with the requirements of 10CFR50 Appendix L (VI)(4)(a) in providing an implementation plan for the Emergency Response Data System (ERDS).
The TV Electric is in the process of changing out the plant computers.

referenced letter, will be replaced by VAX Correspondingly, the operating system will be changed from the Primos 18.3 As a result of operating system to the VMS Version 5.4 operating system.
these changes the Plant Attribute Library (PAL), transmitted as part of the EROS survey, is being re-transmitted as an criclosure to this letter as Please note that the PAL is common required by 10CFR50 Appendix E (VI)(3)(b).Although TU Electric does not expe to both units.
(OPL), aim a prt of the EROS survey, to change substantially, TU Clectric will, as the new computers are installed and tested, reverify the contents of the OFL and inform the NRC of any changes as required by 10CFR50 Appendix E (VI)(3),
10CFR50.72(a)(4) requires that the ERDS be activated as soon as possible but no later than one hour af ter declaring an emergency classification of alert or in order to comply, TV Electric Emergency Plan Proccdures will require activation of the EROS as one of the initial steps in the activation

1XX-91383 Page 2 of 2 The Unit 2 plant computer changcout is p.'ojected for July 1992.
10 Electric expects to install the ERDS sof tware and hardware as part of the changeout.
1U Electric will verify operability and compatibility of the NRC supplied modem and ti new plant computer system during acceptance testing of the computer. Any changes identified to the Data Point Library will be submitted prior receipt of the Unit 2 facility operating license.
TV Electric will provide available dates for the installation testing of the LRD$ in accordance with the NRC supplied test procedure when the Data Point Library changes are submitted.
The Unit 1 plant computer changeout is currently projected for fourth quarter of 1993. As in Unit 2, 1U Electric expects tt install the EADS software and hardware as part of the changeout, lU Electric will verify operability and compatibility of the NRC supplied modem and the new plant computer system during acceptance testing of the computer.
The schedule is still tentative and contains uncertainties that could affect completion.
Since the projected completion date is after the implementation date specified in the rule, TV Electric will prepare and submit an exemption request, to the NRC.
10 Electric will submit the exemption request prior to August 31, 1992, and will provide an implementation schedule for ERDS, including Emergency plan procedures and training, when the plant computcr changeout schedule becomes firm Sincerely
