License Renewal Application Supplemental Information
BVY 11-013 / Attachment 1 / Page 1 of 3 Vermont Yankee Nuclear Power Station License Renewal Application - Supplemental Information Vermont Yankee Nuclear Power Station (VYNPS) provides the following supplemental information to address questions discussed with the NRC staff on teleconferences held on February 9, 2011 and February 10, 2011. The information covers the following areas:
- 1. Neutron-absorbing material
- 2. Buried piping Neutron-Absorbing Material
Background
VYNPS provided additional information related to the Neutron Absorber Monitoring Program in License Renewal Application (LRA) supplemental information letters dated October 14, 2010 (BVY 10-052), December 21, 2010 (BVY 10-058) and February 4, 2011 (BVY 11-010). The program description in Section B.1.31 stated that the first testing of the Boral material would be completed prior to the end of 2014. Based on a teleconference held with NRC staff on February 10, 2011, VYNPS is providing the following supplemental information in order to support the staff's evaluation of the program.
Discussion As stated in BVY 11-010, VYNPS has nine racks installed in the spent fuel pool that were manufactured by Nuclear Energy Services (NES). There are two racks installed which were manufactured by Holtec. Three coupon strings are installed in the NES racks, each holding three Boral coupons.
VYNPS will test one coupon prior to the period of extended operation (PEO) to measure B-10 areal density and to assess the geometric and physical condition of the tested coupon. If coupons are not able to be retrieved and tested or if coupons cannot be demonstrated representative of the Boral in the Holtec racks, then VYNPS will perform neutron attenuation testing using in-situ methods, as described in BVY 11-010, (BADGER or blackness testing method) prior to the end of 2014.
Section A.2.1.37 of Appendix A to the LRA remains unchanged. The program description for Section B.1.31 of Appendix B to the LRA is revised to read as follows:
B.1.31 Neutron Absorber Monitoring Program Proaram Description The Neutron Absorber Monitoring Program is a new program that manages loss of material and reduction of neutron absorption capacity of Boral neutron absorption panels in the spent fuel racks. The program will rely on periodic inspection, testing, monitoring and analysis of the criticality design to assure that the required five percent subcriticality margin is maintained during the period of extended operation.
The program will be initiated prior to the period of extended operation. One coupon will be tested prior to the PEO to measure B-10 areal density and to assess the geometric and physical condition of the tested coupon. If coupons are not able to be retrieved and tested or if coupons cannot be demonstrated representative of the Boral in the Holtec
BVY 11-013 / Attachment 1 / Page 2 of 3 racks, thenneutron attenuation testing using in-situ methods, as described in BVY 11-010, (BADGER or blackness testing method) will be completed prior to the end of 2014.
Commitment 52 is revised to read as follows:
Commitment 52 Implement the Neutron Absorber Monitoring Program as described in LRA Section B.1.31.
Test one coupon prior to the PEO to measure B-10 areal density and assess the geometric and physical condition of the tested coupon. If coupons are not able to be retrieved and tested or if coupons cannot be demonstrated representative of the Boral in the Holtec racks, then perform neutron attenuation testing using in-situ methods, as described in BVY 11-010, (BADGER or blackness testing method) prior to the end of 2014.
Buried Pipingi Backaround VYNPS provided additional information related to the buried piping program in LRA supplemental information letters dated October 14, 2010 (BVY 10-052), December 21, 2010 (BVY 10-058) and February 4, 2011 (BVY 11-010). Based on a teleconference held with NRC staff on February 9, 2011 VYNPS is providing the following supplemental information in order to support the staff's evaluation of the program.
Discussion In BVY 11-010, VYNPS agreed to use a soil corrosivity index greater than 10 as a basis for an increased number of buried piping inspections during the PEO. In accordance with American Water Works Association (AWWA) Standard C1 05, VYNPS will determine the soil corrosivity index based on soil resistivity, pH, redox potential, sulfides and moisture.
Also in BVY 11-010, VYNPS committed to perform at least two inspections of buried carbon steel piping segments in the service water system every 10 years during the PEO, with the number increasing to three inspections if the soil resistivity is < 20,000 ohm-cm or the soil scores higher than 10 points on the soil corrosivity index using AWWA C105. After discussion with NRC staff, VYNPS will revise Commitment 54 to perform at least four inspections of buried carbon steel piping segments in the service water system every 10 years during the PEO. If the soil resistivity is < 20,000 ohm-cm or the soil corrosivity index is higher than 10 points using AWWA C105, the number of inspections of the service water system buried piping will be increased to six.

BVY 11-013/ Attachment 1 / Page 3 of 3 If the soil resistivity is < 20,000 ohm-cm or the soil corrosivity index is higher than 10 points using AWWA C105, the number of inspections of the standby gas treatment system buried piping will be increased to three inspections and service water system buried piping will be increased to six inspections and the inspection regime will be as follows.

= Inspection already completed Commitment 44 addresses performing buried piping inspections during the PEO. This commitment is replaced by Commitment 54; therefore Commitment 44 is deleted. Commitment 54 is revised to read as follows.
Commitment 54 Prior to the PEO, VYNPS will inspect portions of the standby gas treatment system buried piping. The inspections will consist of direct visual examination of a minimum of two sections of piping and cover the entire circumference of at least ten linear feet of piping in each section.
During the PEO, inspections of two carbon steel piping segments in the standby gas treatment system and four carbon steel piping segments in the service water system will be performed every 10 years if measured soil resistivity is > 20,000 ohm-cm and the soil corrosivity index is 10 or less using AWWA C105. If the soil resistivity is <
20,000 ohm-cm or the soil corrosivity index is higher than 10 points using AWWA C105, the number of inspections of the standby gas treatment system buried piping will be increased to three and the number of inspections of the service water system buried piping will be increased to six. Each of these direct visual inspections following excavation will cover the entire circumference of at least ten linear feet of piping.
During the PEO, two inspections covering at least 8% of the total length of in-scope buried fuel oil piping (-40 feet) will be performed at least once every 10 years. If the soil resistivity is < 20,000 ohm-cm or the soil corrosivity index is higher than 10 points using AWWA C105, the percentage of fuel oil buried piping inspected will be increased to 12%.
Soil samples will be taken prior to the period of extended operation and at least once every 10 years thereafter to confirm the initial sample results.
Section A.2.1.1 of Appendix A to the LRA and Section B.1.1 of Appendix B to the LRA remain unchanged.
