Small modular reactor

Energy Disconnect

Misguided policies threaten resource adequacy.

Resource planning is grinding to a halt. From EPA regulations to irrational markets, today’s policy missteps threaten tomorrow’s reliability.

B&W, TVA Plan Small Modular Reactor

Babcock & Wilcox mPower (B&W mPower) and the Tennessee Valley Authority (TVA) signed a contract to prepare and support nuclear regulatory commission (NRC) review of a construction permit application for a B&W mPower small modular reactor (SMR) nuclear plant at TVA’s Clinch River Site in Oak Ridge, Tenn. The DOE awarded a cost-sharing grant to B&W mPower in November 2012. Preliminary work at the Clinch River site is expected to begin once B&W mPower and the DOE sign a cooperative agreement for the grant funds.

The Incredible Shrinking Reactor

Small is beautiful for nuclear developers.

Small modular reactors (SMRs) are nuclear generating units that are about the size of railroad cars and provide about one-tenth to one-fourth the power of full-size reactors. As a result, they cost a fraction of what full-size reactors cost. The reactors are designed to provide between 40 MW and 300 MW of electric power, compared with the 1,100 to 1,700 MW output of larger reactors. In addition, most are expected to cost under $1 billion, compared with the $5 billion to $10 billion price tags of the larger units.
