Stability testing of low-level waste forms

The NRC Technical Position on Waste Form identifies methods for thermal cycle testing and biodegradation testing of low-level waste forms. These tests were carried out on low-level waste forms to establish whether the tests are reasonable and can be achieved. The thermal cycle test is believed adequate for demonstrating the thermal stability of solidified waste forms. The biodegradation tests are sufficient for distinguishing materials that are susceptible to biodegradation. However, failure of either of these tests should not be regarded of itself as a indication that the waste form will biodegrade to an extent that the form does not meet the stability requirements of 10 CFR Part 61. 9 references, 4 figures, 5 tables
