Abstract
An Intermediate Level Waste Store facility for on-site
waste storage is under construction to contain arisings from historic
operations of the Hunterston `A' NPS, Ayrshire. This paper updates previous
a durability design strategy for reinforced concrete structures used in
long-term storage (>100 years) of nuclear waste that incorporates
design-limit flexural cracking. The approach, utilising probabilistic
modelling of deterioration and reliability methods, gives greater
flexibility to the decision-making process for management of concrete
structures depending on the balance chosen between acceptable risk and
maintenance philosophy. The results are compared with contemporary UK Codes
concerning durability of reinforced concrete.
