TerraPower, the Invoice Gates-backed nuclear innovation agency, has launched a brand new small modular reactor (SMR) system paired with molten salt storage unit.

The brand new idea, Natrium, is being developed in partnership with GE Hitachi Nuclear Power. In keeping with the pair, it may very well be used to spice up a 345-megawatt SMR to round 500-megawatts for a interval of as much as 5 hours.

TerraPower, based by Gates in 2008, is creating two separate SMR applied sciences. The sodium quick reactor used within the Natrium idea produces giant volumes of warmth over and above what’s required to drive its steam generators. The corporate has beforehand flagged this as a possible supply of course of warmth or for power storage. The Natrium system offers it a industrial idea for the latter.

“We designed this method with operator enter to doubtlessly enhance their revenues by 20 p.c via using power storage,” mentioned Jay Wileman, GEH president and CEO, in a press release.

The addition of dispatchable energy, by way of the thermal storage, makes the system greater than an costly piece of baseload with out the advantage of scale. A realized Natrium system might, in principle, present some flexibility and grid companies as properly.

Commercialization this decade

The expertise’s builders imagine the additional income makes the expertise extra investable and are bullish about its growth timeline.

“Our distinctive expertise growth capabilities, unmatched financing credibility and achievable funding technique imply that the Natrium expertise will probably be obtainable within the late 2020s, making it one of many first industrial superior nuclear applied sciences,” mentioned Chris Levesque, TerraPower president and CEO. On Friday, one other small reactor firm, NuScale, introduced the U.S. Nuclear Regulatory Fee had accomplished its ultimate security assessment of that firm’s small modular reactors. 

The brand new hybrid challenge from TerraPower is a part of the U.S. Division of Power’s Superior Reactor Demonstration Program. TerraPower declare’s that its participation in that program has garnered curiosity in Natrium from PacifiCorp., Power Northwest and Duke Power.

PacifiCorp confirmed to Greentech Media that it is appearing as a utility adviser for Natrium. Duke instructed GTM that its help of the idea is considered one of its efforts to discover applied sciences that will assist it obtain its objective of net-zero carbon electrical energy by mid-century.

There are nonetheless loads of hurdles to beat on path to that “late 2020s” commercialization.

Financing apart, there’s additionally the problem of testing.

Because it stands, solely Russia has a full-scale testing platform for SMRs. The U.S. Division of Power introduced plans to develop a Versatile Check Reactor (VTR) in February 2019. A VTR may be reconfigured to imitate the operation of a number of SMR configurations.

Earlier this week a consortium of Bechtel Nationwide Inc., TerraForm and GE Hitachi Nuclear Power, was chosen to start contract negotiations for the DoE’s VTR challenge. The plan is to conclude an environmental affect evaluation and finalize the design by late 2021.

As is the case with all nuclear energy, value and building timelines will probably be closely scrutinized. Whereas bigger nuclear reactors used scale to maintain down prices — a technique that is not working for Georgia’s Vogtle Nuclear Plant, the one large-scale challenge within the works within the U.S. — SMR applied sciences hope get the identical outcome from doing the other. If sufficiently small they are often largely assembled in factories somewhat than onsite. The huge requirement for nuclear-grade concrete may be trimmed as properly.

To maintain prices down additional, Natrium’s non-nuclear gear is housed in a unique constructing.

The U.S. Division of Commerce estimates that the absence of a nuclear reactor trade will value as much as $740 billion over the following decade. In a bombshell 2018 report from the United Nations Intergovernmental Panel on Local weather Change, nuclear performed a task in all eventualities that stored international warming beneath 1.5 levels Celsius.

Continued help for a sector with stakes that top is probably going.
