Abstract
The storage facility is located at AL-Tuwaitha nuclear research site; it is intended for temporary storage of the radioactive waste (RW) with low half-life and low or medium radioactivity. The annual doses are calculated for the workers and public of the storage facility from a hypothetical accident involving drums falls to the ground by different climatic conditions. The results show the safety and exposure of the workers normal operational and public in accident scenario during periods to legacy RW drums in storage facility. In this study the results by SAFRAN calculations (SAFRAN is a computer program used to assess the safety of workers in the radiation fields and the main objective of using the program is to know the activities and activities that include high radiation dose affecting the workers and the public and the development of treatments for the purpose Reduced radiation dose) in Table (4) for normal operation showed that the highest radiation dose of the two most active radiation measurements and the sorting of drums was up to 430 μSv, which is acceptable for radiation field workers where (2.5%) of the annual value set by International Commission on Radiological Protection (ICPR) for radiation workers, which amounts to 20 mSv per year. The results of the scenario of the possible accidents occurred. The highest possible dose to be received by the workers in Table (5) is 5.68 μSv in the treatment of the extreme rain incident, which may enter the storage facility due to a fault in the discharge of water. Within the limits of the dose of accidents assumed by the SAFRAN program as an accident dose is the same as the one allowed by the ICPR which is 1 mSv per year, where 5.68 μSv is equivalent to 0.5% of the permissible dose.

Summary
An integral and important part of the safety case, is driven by a systematic assessment of radiation hazards. Waste management facilities and activities are varied in nature, size and complexity, and have different hazards associated with them, both from normal operation and from accidents. The extent and complexity of the safety case and supporting safety assessment will differ according to the facility or activity, and will evolve through its lifetime (e.g. construction, commissioning, and operation). In view of these considerations, a graded approach is required to be applied to the development and review of the safety case and supporting safety assessment [4, 5, 6,7]
