Summary of Green Hab operations: Nothing to report

Summary of Science Dome operations: We were operating the autoclave by the handbook that was provided and as the pressure began to rise to the optimal pressure, it began to drop suddenly. We found that there was a leak out of the threads of the pressure valve that attaches the whole valve assembly to the lid, probably because it was not tightened properly. In order to remedy that, the XO got an adjustable wrench and made a tightening quarter turn on the valve, which caused the leak to stop and pressure, began to rise again. However, a minute later, the upper pressure release segment popped off. Upon inspection, we found that the valve sheared where pressure normally releases. It appears that the valve was already weakened as it sheared cleanly. No threads were damaged, so if a replacement valve assembly can be obtained, the issue should be repairable. The minimum sterilization pressure (17 psi) was obtained only momentarily and no higher pressures were experienced.
