Grading of requirements for radioactive waste activities in nuclear research reactors : radioisotope production facilities

الملخص EN

A graded approach is applicable in all stages of the lifetime of a research reactor.

During the lifetime of a research reactor, any grading performed should not , in any manner, affect safety functions and operational limits and conditions are preserved, so that there are no undue radiological hazards to workers, public or environment.

The grading of activities should be based on safety analyses, and regulatory requirements.

Other elements to be considered in grading are the complexity and the maturity of the technology, operating experience associated with the activities and the stage in the lifetime of the facility.

In order to ensure that proper and adequate provision is made for the safety implications associated with the management and disposal of radioactive waste, the waste is characterized and classified.

The general scheme for classifying radioactive waste as presented in the current study is based on considerations of long term safety, and thus, by implication, disposal of the waste.

This classification provides a starting point for the grading of activities associated with the packaging and disposal of radioactive waste.
