SUBJECT:
COPMENT FROM STATE OF SOUTH dAR0 LINA REGARDING NUMBER OF SPECIMENS REQUIRED FOR 10 CFR PAU 61 WASTE FORM TESTING The purpose of this memo is to address the commerd from Virgil Autrey of the State of South Carolir.e;concerning the number of spe'cimens generally required by NRC for 10 CFR Part 61 waste form testing.
Several consideratioris were important in making the determination that a minimum of duplicate specimens are acceptable for each waste form test.
- 1, NRC has examined the performance of generic types of solidification agents and found under most test conditions that solidification products generally far exceed the minimum 50 psi test criterion for sne compr(ssiveistrength of solidified forms. Secondly, requiring irre than duplicate specimens for six to seven tests and five to six waste streams would generate from 70 to 80 additional test specinens. The expense associated with these specimens can be significant. Finally, NRC requires solidification and testing of multiple specimens from a full scale product .as well as development of process control parameters to assure correlation of test results with actual solidified products sent to burial. We, therefore, believe that duplicate specimens will produce an adequate' base on which to review the acceptability of solidification agents.
