However, a "small" HEPA bypass would not explain why WIPP's sampling system measured more Plutonium 10 hours AFTER the explosion than during the actual explosion, whereas the pre filter samples showed massively more contamination during the explosion; as shown by this WIPP chart provided by the National Atmospheric Release Advisory Center at Lawrence Livermore National Labs.
Post HEPA Radioactive samples highest 10 hours AFTER explosion
Radioactive Readings Largest DURING EXPLOSION
An analysis of WIPP's data, plus information from a source connected with WIPP, indicates that the HEPA filters were not turned on until after the majority of the Radioactivity escaped, otherwise that HEPA bypass must have been designed to vent to the outside during explosive pressures.

I'm confused about your conclusion of "An analysis of WIPP's data, plus information from a source connected with WIPP, indicates that the HEPA filters were not turned on until after the majority of the Radioactivity escaped, otherwise that HEPA bypass must have been designed to vent to the outside during explosive pressures."
ReplyDeleteIf that is true, then wouldn't Station B (post-filter), also show more disintegrations during the initial period of 2/14/14 07:42 - 2/15/14 06:30 because the HEPA filter had not yet been turned on and the bypass was in effect? I would then expect the subsequent period to show fewer disintegrations once the HEPA filter had been turned on and the bypass may have not been necessary as the explosion was already alleviated. Maybe I don't understand how the bypass works?
Also, why do you believe that the majority of the radioactivity escaped in the initial stages of the incident when the measurement data shows that it occurred 10-15 hrs after the CAM alarm?
Answering your last question first, "Station A" is where the raw unfiltered mine exhaust normally vents directly to atmosphere; the readings from that location show Millions of DPM's during the initial explosion and 10 hours later it is in the 100K's. This shows the event produced the most radioactivity, as expected during the initial explosion.
DeleteAt some point after the initial explosion the HEPA filters are turned on. When that occurred, dampers in the EXHAUST of "Station A" redirect the air flow over to "Station B" where the air is HEPA filter and exhausted outside. That means the Station B monitor sees ZERO air flow until AFTER the HEPA switch over takes place; that is the source of your confusion.
