EMERGENCY PLAN REOUEST FOR ADDITIONAL INFORMATION 1.
Although the attachment to your transmittalletter states that all potentially radioactive gaseous effluents exhaust through Stack 1, the revised wording in Section 1.2 of the EP does not identify Stack 1 as the only stack that would see airborne releases.
Resoonse:
Section 1.2 has been revised to state that the Unit I stack is the only stack that would normally contain radioactive elliuents.
2.
The List of Effective Pages should be reviewed against the actual plan, page per page, to ensure consistency. For example, Figure 1.2-1 has no revision number or
+
date, Figure 13-1 has a different date on it than the list indicates, pages 11-2 through 11-7 are not listed and the actual pages need revision numbers and dates, etc.
Resoonse:
i The List of Efrective Pages has been nviewed and revised to agree with the actual plan.
All EP figures have been revised to indicate the date the figure was last revised.
S 3.
Section 2.1.1.2 identifies the Technical Sersices Area (TSA) as the only area within the CEC where a criticality could possibly occur but does not contain a summay of the worst-case criticality scenario that we previously requested. A summag of the consequences similar to the summary in Section 2.1 for the worst-case UF6 release should be provided. In addition, the sentence in 2.0 that reads, "There is no credible probability of nuclear criticality." should be changed to reflect your analysis.
Response
EP section 2.1. has been revised to provide a summary of the consequences of the i
potential worst-case criticality. The wording of section 2.0 has been revised.

The discussion of emergency action levels (EALs) in Chapter 3 should be corrected as shown in the markup of the applicable pages (attached).- The plan must clearly define EALs as criteria established in advance for classifying incidents within a few minutes of the initial report. The purpose of an EAL is to provide the appropriate decision maker with criteria for declaring an Alert or Site Area Emergency based on an initial report that may contain very sketchy information.
Response
EP chapter 3 has been revised in accordance with the recommended changes.
Attachment A A-2
