Metamic coupon sampling program. The purpose of the Metamic coupon sampling program_ is to characterize certain physical and chemical properties of the Metamic sample coupons from the CNS spent fuel storage pool. Per the Reference letter, NPPD committed to remove a Metamic coupon from the spent fuel pool for testing after 2, 4, 8, 16, 20, 24, and 28 years. In addition to measurements and observations of coupon physical characteristics, NPPD stated in the Reference letter that a neutron attenuation test would be performed after 4, 12, and 20 years. This report pertains to the year twelve test.
One Metarnic coupon was removed from the spent fuel pool after twelve years and provided to Holtec International for testing. The testing results are contained in Enclosure 1. Coupon dimensional and density data is included in Section 6.0 of the enclosed report Neutron attenuation testing results are reported in Table 1 of Section 5 .0 of the enclosed report The results meet procedural acceptance criteria and the neutron attenuation results indicate no degradation in Boron-10 content is considered to be proprietary to Holtec International pursuant to 10 CFR 2.390(aX4).
