Design of drystore for intermediate level waste

A new concept in dry radwaste store design has been developed which makes possible significant reductions in project cost and timescale when compared to existing facilities designed to meet current regulations. This new store design eliminates three of the major cost items normally found in stores of this type; the product support structure, the engineered shield floor and the requirement for a heavy shielded charge crane. By the use of novel structural features, the problem of seismic enhancement within the product storage matrix has also been eliminated. This paper describes the main features of the store design and shows how the modular concept can be tailored to suit specific requirements. The design parameters and objectives for the study are identified and the chosen configuration and associated structural design philosophy are described. Major areas of cost benefit inherent in the design are considered, and the various advantages offered by the concept over alternative installations are highlighted
