Abstract: "The Midi Mist (U12n.02) event produced rock spalling along bedding, joint, and fault planes in the U12n.02 and U12n.03 drifts. The spalling in the U12n.02 drift started at about construction station 12 + 75 and was continuous toward the W.P. Most of the spalling in the U12n.03 drift occurred between C.S. 0 + 00 and 7 + 00."

Short-time tensile tests were conducted on irradiated (2 x 10/sup 20/ nvt) and unirradiated Hastelloy-N bar from heats 5911 and 6252. No significant difference in mechanical properties was noted between the two heats. The 1200/sup 0/F ultimate tensile strength was decreased by irradiation from 65 to 80 ksi and 48 to 52 ksi. The 1400/sup 0/F ultimate tensile strength was decreased from 45 to 51 ksi to 32 to 34 ksi. The yield strength was not greatly affected by irradiation at either 1200 or 1400/sup 0/F. The 1200/sup 0/F elongation at fracture was decreased from 15 to 45% to 5 to 11%. The 1400/sup 0/F ductility was decreased from 8 to 26% to 1 to 1-1/2%. Unirradiated uniaxial stress-rupture tests were conducted at both AI and ORNL. No definite difference in stress-rupture properties between heats was noted at either 1200 or 1400/sup 0/F in ORNL tests, although some of the 1400/sup 0/F stress-rupture tests indicated that heat 6252 exhibited greater ductility. The AI verification tests showed a definite ductility difference, with heat 6252 exhibiting greater ductility. This phenomenon was attributed to an inhibition in crack propagation due to microsegregation.

As commercial fuels reprocessing develops, large quantities of radioactive and stable fission rare gases will become available. These gases pose both a problem and an opportunity. When efficient methods of control and recovery are developed, the cost of these materials will be greatly reduced. With increased availability and reduced costs, commercial and government applications would be accelerated. Thus the fission gases which present potential environmental problems, would become useful by-products.
