7.3.7 Processed resin is tested annually as a minimum to
" verify the free standing water content of the packaged In product is within applicable regulatory limits.
addition to the annual verification, the free standing water content is determined whenever process changes occur that may significantly alter system performance.
Tests are performed to verify operability and for ensuring the waste form is similar to that indicated in prequalification testing.
7.3.8 To prevent accumulation of radiolytically generated
" combustible gas in greater than Type A radioactive waste packages containing water and/or organic substances, one or more of the following measures are taken:
