What are the benefits of SMR?

SMRs provide simplicity of design, enhanced safety features, the economics and quality afforded by factory production, and more flexibility (financing, siting, sizing, and end-use applications) compared to larger nuclear power plants. Additional modules can be added incrementally as demand for energy increases.

Why do we need small modular reactors?

Small Modular Reactors (SMRs) are small reactors that are aimed at new markets to tackle global needs for safe, clean, economic energy. In Canada, this could mean new clean energy options for replacing coal, greening mining and improving energy security for remote communities.

Why small modular nuclear reactors won’t help counter the climate crisis?

Nuclear reactors, whether small or large, are not very suitable for responding to variability, because they have high fixed costs (capital) and low variable costs (fuel and maintenance).

How do small modular reactors work?

Like conventional nuclear reactors, small modular reactors harness thermal energy to generate electrical power. For example, the thermal energy heats water into steam, which then powers a turbine, generating electrical power. The Reactor Island houses all of the nuclear systems.

Are SMR reactors safer?

SMRs feature smaller, less robust containment systems than current reactors. This can have negative safety consequences, including a greater probability of damage from hydrogen explosions.

Can small modular reactors help mitigate climate change?

This is one of the direct benefits that it offers towards climate mitigation,” Janardhanan says. As the demand for hydrogen as a fuel for transportation and industry grows, small modular reactors could also provide the energy needed to generate hydrogen, he adds.

Are small nuclear reactors really the answer to our green energy crisis?

Small nuclear reactors are hailed as an answer to our energy crisis, but Jon Yeomans finds problems remain with the untested technology. The hope is that they could reduce the cost of nuclear power dramatically and help the UK to hit its target of net-zero emissions by 2050.

Who makes small modular reactors?

NuScale
NuScale is leading the world into the future of energy and making history with our groundbreaking small modular reactor (SMR)—the first ever to receive U.S. Nuclear Regulatory Commission design approval.

Why are small modular reactors bad?

Small modular reactors won’t achieve economies of manufacturing scale, won’t be faster to construct, forego efficiency of vertical scaling, won’t be cheaper, aren’t suitable for remote or brownfield coal sites, still face very large security costs, will still be costly and slow to decommission, and still require …

What is a small modular reactor?

The NRC refers to light water reactor (LWR) designs generating 300 MWe or less as small modular reactors (SMRs). The NRC has engaged in varying degrees of pre-application activities with several SMR designers over the past several years. In August of 2020, the NRC approved a design for an SMR from NuScale Power, LLC.

Will NuScale’s SMR get approved by the NRC?

The NRC is preparing a rulemaking to certify the NuScale SMR design. Once certified, the SMR will join six other light water reactor designs cleared by the NRC. The regulator is also reviewing the nation’s first boiling water SMR design developed by GE-Hitachi.

Is there an inequity between SMR insurance requirements for power reactors?

In SECY-11-0178, the staff identified a potential inequity between the insurance requirements for facilities with power reactors that produce electrical power equal or greater than 100 MWe per unit and multi-module facilities with SMR designs that individually produce less than 100 MWe, but, in combination, produce more than 100 MWe.

What does SMR stand for?
