Introduction
"* NRC preliminary YELLOW finding of failure to meet the requirements of 10 CFR Part 50.47(b)(5)
"* Failure to maintain the design function of the Alert and Notification System (ANS)
FENOC FirstEnergy Nuclear OperatngCopanýy
Chronology-susan Vicinie S.Purpose:
Achieve a Common Understanding of the History Related to Beaver Valley Power Station (BVPS) Alert Notification System FENOC FstEnergyNuce tm
Chronology e February 1983, Performed Independent Study of the ANS
- March 1984, BVPS Submitted Design Report
"* December 1985, FEMA Issued Independent Quality Assurance Verification Report that Concluded the ANS Conformed to Regulations
"* January 1986, NRC informs BVPS that ANS Requirements have been met FENOC FirstEnergy Nuclear O tin Company
Chronology
- 1986 - 2000 Conducted Annual Siren Tests
- March 1998, BVPS Identified PHAD Maintenance & Testing Procedures Did Not Exist
- December 1999, Agreement with Duquesne Light Company to maintain the PHADs
- May 2001, Revised Emergency Preparedness Administrative Procedure
- August 2001, NRC Identified PHAD Maintenance & Testing Deficiencies FENOC FrstEnergy Nuclear OperatingCompany'
Chronology
- October 2001, Performed Annual Siren Test Using Revised Procedure
- October 2001, Established Plan to Replace PHAD Coverage with Sirens
- March 2002, NRC Notified BVPS of Preliminary YELLOW Finding FENOC FirstEnergy Nuclear Operating Company
Oh ronology
- April 22, 2002, Conducted As-Found Test of Existing Siren Coverage in a Sampling of PHAD Locations
- April 2002, Installed Additional Sirens to Enhance Coverage
- May 2-3, 2002, Tested Enhanced System with FEMA Subject Matter Expert
Significance Perspective Larry Freeland
- Key Points:
- Our Original ANS Included PHADs Which Deteriorated Over Time
- Consequence is Minor Based on New Information and Additional Testing FENOC FirstEnergy Nuc/ear Operating Company
Significance Perspective
"* Population Estimate of the Beaver Valley 10 Mile (total) EPZ is 126,500
"* Population Estimate of the Beaver Valley 5 Mile (total) EPZ is 16,000 or 4,000 Homes
"* PHADs served < 3% of the 0-5 mile EPZ
"* PHADs served < 4% of the 10 mile EPZ FENOC FirstEnergy Nuia prtn opn
Estimated ANS Population Distribution 3%
0-5 Mile EPZ FENOC FirstEnergy Nuclear Operaing Compan'y EM Homes without PHADs MI Homes with PHADs
ignificance Perspective
- Recent "As-Found" Siren Testing Data
- 12 Locations Near PHAD clusters within 0-5 EPZ
- 9 Locations had acceptable audible results
- 3 Locations had unacceptable results
- Siren audibility criteria met in - 75% of tested PHAD locations FENOC FirstEnergy Nuclear OpeItngCompany S
gnificance Perspective
- Additional Considerations
- Many PHADs Within Siren Coverage Contours
- Siren Coverage Overlap
- Testing w/FEMA Determined Design Sound Attenuation Appeared Conservative
- Coverage beyond 70db contours meets 60 db criteria for low population areas FENOC FirstEnergy Nuclear Ope&rating C7opany Si 0
Testing Results Reveal an Estimate of < 1 % of the Population was Potentially Affected by PHAD Deficiencies
> 990/0
< 10/0 FENOC FirstEnergy Nuclear OeatingCopany, El Total Population MI Potential Affected Population
Significance Perspective
- Test Performance Criteria for the ANS was met without Reliance on PHADs
- Siren availability exceeded 90% criteria (Actual > 95% Cumulative Average)
- Telephone survey criteria of 70%
(Actual > 85%)
FENOC FirstEnergy Nuclear OperatingCmpany
Emergency Preparedness Significance Determination Process No No Yes
Significance Perspective
- YELLOW
- "A finding of substantial Safety Significance"
- "A finding placed in context through SDP can result in a risk significance level (color) that exceeds the actual impact on public health and safety" FENOC FirstEnwrgy Nuclear Oprting opany
Significance Perspective
==
Conclusion:==
"* PHAD Deficiencies Resulted in Original Design of ANS Not Being Fully Maintained
"* Based on Recent Testing, the "Essentially 100%" Requirement for Functionality of the ANS was met and the Impact on Public Health and Safety was Very Low FENOC FirstEnergy Nucear Operating Compan'y
Cause Analysis and Corrective Actions - Jim Lash Beaver Valley Senior Management Recogn izes the Importance of Issue e Initiated Highest Level Condition Report
- Used aC ross Functional Team to Perform a Root Cause Analysis and Develop Corrective Actions FENOC FirstEnergy Nuclear Operating Company
Cause Analysis 9 Established Root Cause:
A Formal Testing & Maintenance Program Was Not Implemented to Ensure Satisfactory Performance of the PHADs FENOC FirstEnergy Nuclear Operating Company
Corrective Actions
- Actions to Correct:
- Implemented Interim Measures for Assuring that the Population is Notified in the Event of an Emergency at BVPS
- Conducted Training on the Design Basis Document with the EP Section FENOC FirstEnergy Nuclear Operating Company
Corrective Actions
- Installed and Tested Additional Sirens to Eliminate the need for PHADs
- Submitted Revised Design Report that removed PHADs from the BVPS ANS
- Self-Assessment to be Performed in September 2002 FENOC FirstEnergy Nuclear Operating Company
ummary - Lew Myers
"* We Failed to Maintain and Test the Design Function of the PHADs
"* We Fixed the Problem
- Based on Siren Coverage Analysis Safety Significance is Very FENOC FIrstEnergy Nuclear Operating Cmany S
