Decontamination, cleaning and

Special considerations need to be evaluated for decontamination and clean up of difficult materials. Eor example,... 

CryoGenesis claims the Cryogenesis system offers the following advantages over other decontamination and cleaning technologies ... 

Laboratory coats or gowns and gloves are worn to prevent contamination or soiling of street clothing and hands. Protective clothing must be removed and left in the laboratory before leaving if contaminated, it must be decontaminated and cleaned or, if necessary, destroyed. 

Immediately after decontamination and clean-up, personnel should discard the protective clothing and wash with only soap and water. 

The provision of bund walls or dykes around equipment could be considered to be good practice. They need to be sized to retain the entire contents of the equipment should catastrophic failure occur.Van Houten recommends that provision should be made for the material to be pumped to a spare bioreactor or a continuous steriliser. Decontamination and cleaning up of the residual puddles are then carried out using the appropriate safety precautions. 

Properly stored in well-defined spaces >- Checked at suitable intervals >- Repaired or replaced before further use when it is discovered to be defective >- Ensure that any PPE that is contaminated by a substance hazardous to health is either decontaminated and cleaned or destroyed if necessary. 

After the above immediate actions are accomplished, decontamination and clean-up will be... 

The decontamination and clean-up of the EBWR Facility to allow its Tuu estricted reuse. 

Phase rV will consist of the removal of the reactor cavity liner and shield items, decontamination of the cavity and fuel pool and a general decontamination and clean-up of the EBWR shell. This work will consist of removal of tiie lead brick shielding and removal of the carbon steel cavity liner. The majority of this material should be able to be disposed of as clean scrap. Some of this material will require disposal as radioactive waste, which is most likely for those materials near the former core region where the highest neutron fluences were present. Materials behind the upper half of the reactor vessel are very likely to exhibit no induced radioactivity and should be able to be recycled.
