Significance Small modular reactors (SMRs), proposed as the future of nuclear energy, have purported cost and safety advantages over existing gigawatt-scale light water reactors (LWRs). However, few studies have assessed the implications of SMRs for the back end of the nuclear fuel cycle. The low-, intermediate-, and high-level waste stream characterization presented here reveals that SMRs will produce more voluminous and chemically/physically reactive waste than LWRs, which will impact options…

Resource Requirements and Proliferation Risks Associated with Small Modular Reactors

An initial assessment of the proliferation risks associated with notional SMR designs compared to standard light water reactors (LWRs) using a Markov model indicates that SMRs based on LWR technology have higher resource requirements as compared to gigawatt-scale reactors, while SMRs with long-lived cores have much lower resource requirements but a higher fissile content in the spent fuel they generate.

Spent Nuclear Fuel

The primary waste form resulting from nuclear energy production is spent nuclear fuel (SNF). There are a number of different types of fuel, but they are predominantly uranium based, mainly UO 2 or,

Burning waste or playing with fire? Waste management considerations for non-traditional reactors

ABSTRACT Nuclear energy-producing nations are almost universally experiencing delays in the commissioning of the geologic repositories needed for the long-term isolation of spent fuel and other

Variations in nuclear waste management performance of various fuel-cycle options

The variations in the nuclear waste management performance have been assessed for 40 fuel-cycle examples with the calculation of the mass, activity, toxicity and decay heat of spent nuclear fuel and

Management of Radioactive Waste Containing Graphite: Overview of Methods

Since the beginning of the nuclear industry, graphite has been widely used as a moderator and reflector of neutrons in nuclear power reactors. Some reactors are relatively old and have already been
