GEH spent about half a billion dollars designing, testing and certifying the ESBWR. Despite that investment, the 1,520 MWe Enhanced, Simplified Boiling Water Reactor (ESBWR) design documents are just gathering dust with no active projects in sight. GEH is a joint venture between US-based GE, a $95 billion annual revenue conglomerate and Hitachi, a Japanese…
GE-Hitachi issued a press release on October 5 indicating that they will be working with DTE to determine the resource requirements and schedule for performing the detailed design work necessary to build an ESBWR (Economic Simplified Boiling Water Reactor) as Fermi Unit 3. Though DTE has not announced a decision to build the facility, it…

Sometimes those stories have happy endings, other times they leave you hanging and waiting for the next installment. I just finished such a book – Light Water:…
Shane and Rod discuss boiling water reactors, one of the two types of established light water reactors. There are two main types of light water reactors, pressurized water reactors (PWR) and boiling water reactors (BWR). They share some characteristics, but also have a number of differences. There are plenty of sources of information on the…
