~'~ 4p8 The NRR staff has performed in evaluation in response to the ACRS concerns regarding the lack of a rapid direct depressurization capability in the System 80 design, This new iriformation relates to all CE facilities without this capability, incl'uding Palo Verde, Units 1, 2 and 3.

Since the staff evaluation was completed prior to the Ginna incident, and since other preliminary information concerning the System 80 design has been recently generated within the NRC staff, this Supplemental Safety Evaluation Report (Enc"Iosure 1) is a draft, and does not complete our review in this area.

The staff review of Feed and Bleed capability in the System 80 design will 'be finalized at a later date.

The enclosures to this letter'epresent the present status of the NRC staff's review of this issue, which are provided for your information.

We encourage you to join the CE Dwners Group investigation of feed and bleed.

If you have any questions concerning this matter, please contact the project manager, Emanuel Licitra on (301) 492-7200.
