Reflections on Vermont Yankee - 1

Elk River Generating Station, Rural Cooperative Power Association, Elk River, Minnesota.

The Elk River reactor, as it was generally known in the AEC parlance of the day, was a pioneering effort in America's nuclear energy history.  Hailed widely as "Rural America's first atomic power plant," the intention was to provide a pilot installation of a small, simple, and inexpensive nuclear steam supply system that could be duplicated at many far flung locations.  Unfortunately for the concept, the Elk River plant in the end proved unable to meet the task for technical reasons; yet, it remains firmly in history as one of the well known early nuclear energy installations.  What follows is a brief history of the project and its major players.

Among the many different reactor concepts being investigated in the late 1950s and early 1960s was the idea that the steam produced by a boiling water reactor, which normally goes straight to the turbine building, could be superheated (or have further heat added once it was already steam) by nuclear energy. This would greatly increase the efficiency of the plant, as well as make dry steam at a high pressure that would allow the use of (less expensive) commercially available equipment in the steam plant. Two reactors were built to investigate the idea of performing both processes in essentially the same reactor-one in South Dakota and (perhaps incredibly to today's readers) another of a very different design on the island of Puerto Rico.

Yesterday, the Nuclear Regulatory Commission announced that its commissioners had approved the award of a Construction and Operating License (COL) for DTE Energy's prospective Fermi Unit 3, to be built on the site of the existing Fermi-2 near Detroit, Mich. The COL will also notably be the first for the GE Hitachi ESBWR, or "Economic Simplified Boiling Water Reactor," a Gen-III+ nuclear plant with passive safety.

This is the last of the three-part series presenting the opinions of nuclear industry experts on the closing of Vermont Yankee.  Thank you to Dan Yurman for helping to coordinate all of the authors/articles in this three-part series.

This is the second of three posts presenting the professional opinions of experts in the nuclear field on the Yankee Vermont closing.

• This week the GE-Hitachi ESBWR design received its Design Certification from the Nuclear Regulatory Commission.

Vermont Yankee will go into decommissioning at the end of its current fuel cycle. The last day of operation for the nuclear plant is now set for December 29, 2014. Entergy, the owner, elected this course last year after financial analysis indicated the plant's unprofitability in a future of projected low natural gas prices.

Yesterday, the saga of nuclear energy in post-Fukushima Japan reached an important milestone as the final utility that owns nuclear power plants in that country applied to the regulator for restart, in an event that snuck under the radar of most news venues.

The recent U.S. Environmental Protection Agency announcement of policy regarding carbon emissions from power plants has triggered a renewed interest in nuclear energy over the past few weeks; along with this of course comes a focus on small modular reactors (SMRs) and their availability for replacing existing fossil-fueled plants or facilities. We have discussed this topic here at ANS Nuclear Cafe before, in terms of the possibility of adding an SMR onto an existing facility-see "The Hook-Ons."

Our Sierra Club local chapter recently sponsored a joint presentation-by two local anti-nuclear groups. A small audience of attendees heard of the horrors that citizens might expect during Vermont Yankee's upcoming decommissioning. The presenters claimed that their participation in decommissioning will be needed to insure that all goes well because Entergy, and the US Nuclear Regulatory Commission, can't be trusted. Included as usual was a litany of things about to go wrong-all caused by nuclear power!
