Summary
A radiological assessment has been made of the management options for waste materials containing very low levels of radioactivity arising in the decommissioning of a pressurised water reactor (PWR). Estimates have been made of the masses of materials activated and contaminated to within three limits of specific activity, 0.37, 3.7 and 37 Bq g-1, at three times after reactor shutdown, 5a, 25a and 100a. The disposal options considered are shallow land burial, at a municipal landfill site or at the reactor site, and disposal on the seabed in coastal waters or the deep ocean. It is assumed that there is no special treatment to reduce or eliminate the potential radiological hazard. Consideration has also been given to the recycle of contaminated steel.
The radiological impacts of all the management options for the wastes considered were found to be small. It may therefore be acceptable to allow such very low-level wastes to be disposed of without special restrictions provided that the level and type of activity of the wastes can be verified.
