“…The ten to one dilution assures safe dilution of up to 8 percent hydrogen to less than 25 percent of the lower flammability limit in air based on theoretical amount of hydrogen from sampling a "best estimate" for a single scrap basket MCO after two years of interim storage. This "best estimate" single scrap basket MCO is the baseline MCO in the CSB process flow diagram by Klem and Pajunen (2000). Duncan (2001) shows that expected hydrogen concentrations for this case are 6.0 percent at zero year and 8.0 percent at two year storage time intervals.…”

“…A magnetically coupled low-pressure readout unit is later installed on the exterior surface ofport number 1 blind cover plate of the K East Basin monitored MCOs. The weight of the lowpressure readout unit is based on Klem and Pajunen (2000).…”

“…The original blind cover plates are reinstalled on the 199 MCOs that contain high-pressure sending units and a redesigned blind cover plate (Stream MW-8) is installed on the four monitored MCOs. Weight of the sending units is based on Klem and Pajunen (2000). Klem and Pajunen (2000).…”
