External links modified
editHello fellow Wikipedians,
I have just added archive links to one external link on GE BWR. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:
- Added archive https://web.archive.org/20131029195906/http://www.houseoffoust.com/fukushima/ge-bwr6.pdf to http://www.houseoffoust.com/fukushima/ge-bwr6.pdf
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Advantages and Disadvantages
editThe section should focus on specific features of the GE design, and not repeat general differences between BWR (more compact, but also has radioactive steam in the turbine house) and the PWR (more complex, but allows system separation of primary loop and normal water in the secondary loop). So what are the advantages of DE BWR compared to BWR from other companies? --Gunnar (talk) 20:56, 18 February 2018 (UTC)
- You seem to mean GE BWRs instead of "DE" !--2A02:1206:4596:AF0:747D:F051:DB58:EE89 (talk) 13:11, 11 February 2020 (UTC)
Lead must summarize; infobox is supplementary
editJust now I added the following material to a lead which was far too short.
The progenitor of the BWR line was the 5 MW Vallecitos Boiling Water Reactor (VBWR), brought online in October 1957. Six design iterations, BWR-1 through BWR-6, were introduced between 1955 and 1972.
This was followed by the Advanced Boiling Water Reactor (ABWR) introduced in the 1990s and the Economic Simplified Boiling Water Reactor (ESBWR) introduced in the early 2010s.
As of August 2018, 83 reactors of this design family have been built, of which 67 reactors operational.
The design garnered world attention in the aftermath of the INES level 7 Fukushima Daiichi nuclear disaster of 11 March 2011. GE had been a major contractor to the Fukushima Daiichi Nuclear Power Plant in Japan, which consisted of six boiling water reactors of GE design. The reactors for Units 1, 2, and 6 were supplied by General Electric, the other three by Toshiba and Hitachi. Unit 1 was a 460 MW boiling water reactor from the BWR-3 design iteration introduced in 1965 and constructed in July 1967.
After the plant became severely damaged in the Tōhoku earthquake and tsunami, loss of reactor core cooling led to three nuclear meltdowns, three hydrogen explosions, and the release of radioactive contamination in Units 1, 2 and 3 between 12 and 15 March. Safe operation of this reactor design family depends on continued coolant flow at all times during operation, and for a quite a while[quantify] after operation ceases.
I don't really know anything, but I was able to pastiche a rough outline together from this page and related pages. Dates, quantities, and citations all remain a work in progress.
That's it for my piece. Amend or redact as you see fit.
That said, it boggles my mind that the previous lead didn't even mention the original design premise that active coolant flow could be maintained under any eventuality, with not a fast process to mothball a reactor into a quiescent state where coolant flow could be safely suspended. GE owns that original design decision, for better or worse. — MaxEnt 15:00, 17 November 2021 (UTC)
Nothing about BWROG ?
editDoesn't BWR Owner’s Group finally deserve an article in Wikipedia?--Lamiot (talk) 19:40, 19 December 2022 (UTC)
