The final design document for the MMS reports: "The measured mass of the ACD MMS/MLI is 39.455 kg."
Using detCheck v1r5 and its summary.exe application, we find that the blanket material results in:
blanket: #Log = 5 #Phys = 7 Total volume = 303798 302152 cu cm Mass = 37974 37769 gm
Seems fairly close.
Joanne ran the test application in detCheck which checks for overlaps - none were found.
