20472 FEMA MEMORANDUM FOR: Ronald L. McCabe DEC 4 2007 Regional Assistance Committee Chair FEMA Region VI1 FROM:
c Daniel G. Wilcox Acting Chief Radiological Emergency Preparedness Branch
SUBJECT:
Replacement of Wolf Creek Nuclear Operating Corporation (WCNOC) Siren System This is in response to a letter submitted by Mr. Kevin J. Moles, Manager, Regulatory Affairs for WCNOC, dated November 2,2007, requesting approval of the replacement of the WCNOC siren system. FEMA Headquarters review of WCNOCs siren upgrade proposal has been completed. WCNOC is proposing a one-for-one replacement of sirens in the basic locations for eleven (1 1) existing mechanical sirens with eleven (1 1) new state-of-the-art sirens. This upgrade will result in an increase in the level of sound coverage compared to the current FEMA-approved siren system.
Based on our review of the WCNOC proposal we conclude that the proposed upgrade to the WCNOC Alert and Notification System (ANS) is in compliance with FEMAs ANS guidance contained in NUREG-0654 and FEMA-REP-10. Therefore, approval of the WCNOC siren replacement is granted, conditional on the following three (3) future items:
-\\
This is to demonstrate that the ANS will work as designed. The acoustical test protocol should be submitted to FEMA Region VI1 in a timely manner prior to such testing for its approval. This is to ensure that the testing method, if followed, will provide sufficient data to demonstrate proof-of-design to FEMAs satisfaction. At your discretion you or a member of your staff may request to be present when the WCNOC conducts the acoustical test.
- 2) The new radio-system upgrade with repeater functionality must be tested for performance and reliability. In addition, a Failure Mode and Effects Analysis (FMEA) of the complete A N S should be performed by WCNOC.
- 3) The WCNOC final design report should contain, among other things, the acoustical test results, the FMEA and new system maintenance and testing procedures. This report should be submitted to FEMA for review and approval.
The proposed new sirens have different features (related to their ability to operate on battery, integral sensors and different part configurations) that require different testing and maintenance strategies than those used for the present sirens. The new systems maintenance and testing procedures should be reviewed to make sure that the ANS will continue to operate in accordance with its design objectives over the long term. Obviously, this review will occur after the new sirens and radio control system are installed.
Reviewing the final design report will allow FEMA the opportunity to independently determine that the new systems testing and maintenance procedures are effective and in compliance with FEMA policy and guidance.
If you have any questions regarding this matter, please feel free to contact Mr. Russ Gates at (703) 605-1518.
