Thanks for the comment. I basically...Cosmoskitten,<br /><br />Thanks for the comment. I basically agree with everything you said. The issues with backfitting a filter are (as always with any backfit): performance, reliability, economics, and "unintended consequences". This dialog was started almost 30 years ago, suspended for a time, and has now come back to life. It's going to be an interesting next year or two as the debate evolves to some resolution.<br /><br />Thanks for reading my blog!Sherrell R.

There also are closed valves that can be opened in order to bypass the rupture disc, and start venting before the disc bursts.<br /><br />If you do not have the power or personnel to open or close these valves, I suggest that that venting through a filter probably is the best idea.<br /><br />Regarding filter resiliency, there is the "gravel bed in a concrete vessel"-filter, installed in 1985 at the now decommissioned Bareseback reactor. Its an expensive solution due to its large volume (10 000 m3 is IIRC), but its a very predictable thing due to its simplicity.<br /><br />Cosmoskittenhttps://www.blogger.com/profile/06199392509873985738noreply@blogger.comtag:blogger.com,1999:blog-1211624219772149197.post-69021013245574087952013-04-01T08:57:46.981-04:002013-04-01T08:57:46.981-04:00and then you have the water/zeolite filtering pond...and then you have the water/zeolite filtering pond concept, which is hardly likely to lose effectiveness just because of a little thing like a hydrogen blastAnonymousnoreply@blogger.com
