MISCELLANEOUS GENERAL ASSUMPTIONS:
"* Vent Vent A:
Auxiliary Building, Air Ejector(s).
"* Vent Vent B:
Safeguards (filtered),
Fuel Building (filtered),
Containment Purge (filtered), Waste Gas Decay Tank area.
"* Process Vent: Waste Gas Decay Tanks, Containment Vacuum.
"* Containment leakage:
MIDAS uses the higher of the two CHRRMS monitors to calculate the release.
"* Air Ejector Monitors:
MIDAS adds the Air Ejector release to the associated vent vent release.
"* Main Steam and AFWPT:
MIDAS adds the flows from each "open" and "status unknown" valve to calculate the total flow for a particular steam line.
MIDAS sums the releases from all three steam lines and AFWPT to calculate the total release.
"* For Vent Vents and Process Vents, MIDAS uses the highest radiation monitor indication on the affected pathway to calculate dose projections.
"* For "Quick Dose" defaults:
Unidentified mix, ground level, all release points active, and noble gas and iodine.
"* NAPS DEFAULT FLOW RATES:
