EXEMPTION 1.
The Texas Utilities Electric Company (TV Electric) is the holder of Facility Operating License No. NPF-87, which authorizes operation of the
. Comanche Peak Unit ~ 1 reactor at a steady-state power level not in excess of 3425 megawatts thermal..The facility is a pressurized water reactor located at the' licensee's site in Somervell County, Texas. This license provides, among othe.r finngs, that the facility is subfa et to all Nies, regulations, and orders of the Cammission.
II.
Section VI(4)(d) of Appendix E to 10 CFR 50, states that "Each licensee shall. complete implementation of the ERDS [ Emergency Response Data System] by February-13,-1993, or before initial escalation to full power,
' whichever comes later."

. By letter dated June 1,1992, the licensee requested a schedular exemption from the requirements of Section VI(4)(d) of Appendir E.
The licensee stated that they planned a replacement of the Comanche Peak Steam Electric Station. Unit I computer system during the third refueling outage scheduled during the fourth quarter of 1993.
III.
The licensee's request for a schedular exemption from the requirement of Appendix E to 10 CFR 50 Section VI(4)(d) is based on a planned change-out of the computer system which drives the ERDS.
The change-out is to be completed by fourth quarter of 1993.
The licensee states that if the exemption is not granted, it would be required to install two different Ef;DS for the same reactor within one year, and that this would result in redundant and unnecessary costs.
The purpose of the rule requiring installation of ERDS is to assure l
that all power reactors, except for Big Rock Point, install an ERDS in a timely manner.
The licensee stated that it will install an ERDS within four months after installation of a new computer, thus it will comply with the l
intent of the regulatien.
The ERDS is informational only, and does not affect plant safety.
For these reasons, we conclude that granting a schedular exemption from Appendix E,Section VI(4)(d) of 10 CFR 50 will relieve the licensee from unnecessary hardship and redundant costs of installing and testing two ERDS systems within one ye:r.
Therefore, the licensee's request is granted.
, IV.
.[
Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12(a)(1), this exemption is authorized by law, will not present an undue risk to the public health and safety, and is consistent with the common
-defense and' security. The Coramission further determines that special circumstances, as provided in 10 CFR 50.12(a)(2)(iii), are present justifyir.g the exemption. The exemption would provide only temporary relief from the applicable regulation in that the licensec has extended the installation of the ERDS to allow replacement of its Unit I computer system.
Accordingly, the Commission hereby grants an exemption as described in Section III abose frem Appendix E,Section VI(d)(4) of 10 CFR Part 50 to extend the completion date of the ERDS.
Pursuant to 10 CFR 51.32, the Commission has determined that the grant', af the Exemption will have no significant impact on the environment (57 FR 38884).
This Exemption is effective upon issuance.
