Eric Schrader Tel/email: 301.287.3789 Performance Indicator: EP03, Alert and Notification System Reliability Site-Specific FAQ (Appendix D)? Yes FAQ requested to become effective: 1Q2015 PI data Question Section NEI 99-02 Guidance needing interpretation (include page and line citation):

Revision 7 (Clean Copy), page 58:

19 Data Reporting Elements 20 The following data are reported: (see clarifying notes) 21 22

  • the total number of ANS siren-tests during the previous quarter 23
  • the number of successful ANS siren-tests during the previous quarter Event or circumstances requiring guidance interpretation:

How does a plant initially report alert and notification system reliability for a new siren system where there were no sirens previously?

What is the NRC resident inspectors position?

The guidance is unclear on start-up of this indicator. Therefore, the SRI seeks clarification from the ROP Working Group.

Potentially relevant existing FAQ numbers None.

Response Section Proposed Resolution of FAQ:

In initiating EP03 reporting data for a new siren system (where there were no sirens previously), data is entered over the 12 month period starting from the implementation date of April 1, 2014. Each quarter results will be submitted in accordance with NEI 99-02 Rev 7. Zeroes are entered for the trailing quarters until four quarters of data have accumulated.

NRC Response The staff agrees with the proposed resolution for this FAQ, upon incorporation of the following revision:

In initiating EP03 reporting data for a new siren system (where there were no sirens previously), data is entered over the 12 month period starting from the implementation date of April 1, 2014. Each quarter results will be submitted in accordance with NEI 99-02 Rev 7. Zero should be entered for the 12 month quarterly average until four quarters of data have accumulated.

FAQ 14-05 (Final)

Reporting New Siren System Data Page 2 of 2 Revised 10/22/2014 Starting April 1, 2014, the licensee will submit the EP03 PI quarterly results in accordance with NEI 99-02 Rev. 7. The EP03 PI will be valid once four quarters of data have been accrued.

This resolution is consistent with the approach previously discussed in the ROP Working Group on the validity of the EP03 PI for new plants at a new site (the proposed approach was initially discussed in the December 1, 2011 ROP Working Group public meeting (Accession No. ML11350A092)).
