SUBJECT:
CORRECTION OF SAFETY EVALUATION (TAC NOS. M96675'AND-M96676)
Dear Ms. Johnson:
,M+
-N On November 25, 1996, the U.S. Nuclear Regulatory Commiission (Commission) issued Amendment No. 176 to Facility Operating LicensezNo.-DPR-39 and Amendment No. 163 to Facility Operating License No. DPR-48 for the Zion Nuclear Power Station, Units 1 and 2, respectively. ;The amendments were in response to your application dated October 4, 1996, and' supplemented on November 6, 1996.
The amendments added a Mode of Applicability to Technical Specification
)
i 3.2.3.D, Inoperable Rod Position Indicator Channels. Conversations with members of your staff on December 5, 1996, indicated that there was an error l
in the safety evaluation (SE) in that a sentence in paragraph 2.0 of the SE stated that hot shutdown can only be achieved with the reactor trip breakers j
open. This is not correct, since chemical shim is also available to ensure shutdown margin limits are met.
Enclosed is a corrected SE. For ease'of i
incorporation, the entire SE is being provided. We apologize for any inconvenience this mistake may have caused.
vincerely, 1
