Description
Summary:It is possible that hundreds to perhaps thousands of new nuclear power reactors could be deployed this century to help meet the growing global demand for electricity. Underground reactor siting is proposed as a potentially superior alternative to surface siting. Past studies and experience with underground siting proved the engineering feasibility and revealed numerous safety, security, environmental and aesthetic advantages, but in spite of these advantages the added cost associated with underground siting continues to be viewed as an impediment. Recent work on the underground nuclear park (UNP) concept, however, indicates the potential to reduce per-reactor capital and operating cost below that for conventional surface siting. In addition, under a closed fuel-cycle policy, reprocessing plant, fuel re-manufacturing facilities, fast spectrum reactor(s), and waste disposal facilities could also potentially be located underground as part of the UNP. Work to date has included underground design concepts and excavation cost estimates for UNPs in bedded salt and granite, and ideas for UNP-based energy system applications. The UNP approach has the potential to reduce many of the cost, waste management, safety, and security concerns currently associated with nuclear power.
