SUBJECT:
Beaver Valley Power Station, Unit No. 2 Docket No. 50-412, License No. NPF-73 Emeraencv Response Data System Data Point Library Update In accordance with reporting requirement 10 CFR 50, Appendix E, Section VI.3.a, updates of the Emergency Response Data System (ERDS) Data Point Library (DPL) for Beaver Valley Power Station (BVPS), Unit No. 2 (BV2) are provided. Per letter L-15-046, dated March 2, 2015, FirstEnergy Nuclear Operating Company (FENOC) notified the NRC of changes made to the BVPS Unit No. I (BVI) ERDS DPL that were due to the replacement of a radiation monitoring system. It was not recognized at that time that the BV2 ERDS DPL was also affected by that replacement. This issue has been entered into the corrective action program. The attachment of this letter includes the required details of the changes to the BV2 ERDS DPL, and the enclosure provides copies of the updated DPL pages.
There are no regulatory commitments contained in this letter. If there are any questions or if additional information is required, please contact Mr. William C. Cothen, Manager -
Regulatory Compliance, at 724-682-4284.
Sincerely, Eric A. Larson

Reactor DPL Point Description of Change(s)
BV2 XR013 Date: Changed to "02/02/2015" Plant Spec Point Desc: changed to "IRM-GW-109 LRNGM" Engr Units/Dig States: "CPM" to "uCi/sec" Engr Units Conversion: to "Xe 133 CF = cps/uCi/cc" Minimum Instr Range: changed to "6.8E-01" Maximum Instr Range: changed to "6.8E+03" Alarm/Trip Set Points: changed to "normally N/A" Unique System Desc.: changed to I minute average data. System design is such that either the RM-1GW-109 low range or high range noble gas monitor for each pathway will be in service. At a concentration of 1E-02 uCi/cc on the low range monitor, flow will normally swap to the high range monitor. The listed minimum and maximum instrument ranges listed are based on system software parameter limitations and pathway ODCM release flow rate. In addition, the maximum range is based on a release concentration of 1E-02 uCi/cc, limited by the automatic swap to the high range monitor.
Note: Because actual pathway release flow rate may vary, the "Minimum Instr. Range" and "Maximum Instr. Range" may not reflect the actual instrument ranges. Site dose assessment corrects the uCi/s for source term and flow rate differences depending on selected default source term and decay period. RM-1GW-109 monitors for low range noble gases at the discharge of the Gaseous Waste Disposal Blowers. Provides alarms to warn the operator of abnormal releases and provides input to calculate integrated release data.

System design is such that either the RM-1GW-109 low range or high range noble gas monitor for each pathway will be in service. At a concentration of 1E-02 uCi/cc on the low range monitor, flow will normally swap to the high range monitor. Minimum and maximum instrument ranges listed are based on Xe-133 and pathway ODCM release flow rate. Maximum range is based on monitor parameter setting and ODCM release flow rate. Note: Because actual pathway release flow rate may vary, the "Minimum Instr. Range" and "Maximum Instr. Range" may not reflect the actual instrument ranges. Site dose assessment corrects the uCi/s for source term and flow rate differences depending on selected default source term and decay period. RM-1GW-109 monitors for high range noble gases at the discharge of the Auxiliary Building shielded area exhaust fans and at the discharge of the Gaseous Waste Disposal Blower. Site dose assessment corrects the uCi/s for source term and flow rate differences depending on selected default source term and decay period. Provides alarms to warn the operator of abnormal releases and provides input to calculate integrated release data.
