This work originates from a task assignment. This basic data report is for design and fabrication of a canister penetration system for use in these experiments. The basic system was designed and fabricated as a result of a previous task assignment and three associated task plans. The new system, which will be used on canistered waste forms produced during the DWPF Start up Test Program, will be a modification of the previous systems. Hence the seven items identified in the next paragraph have been previously designed, fabricated, and tested but will be required as part of the overall system. The canister penetration system to be designed and fabricated shall consist of (1) a device which can penetrate the canister above the glass line while preventing the mixing of the air within the canister with the air in the environment, (2) a sensor for measuring the relative humidity and dew point of the air within the canister, (3) a sensor for detecting the pressure of the system before penetration and the pressure of the canister and system after penetration, (4) a vacuum system for evacuating the canister penetration system, (5) a connecting port to a mass spectrometer for on line analysis of the air within the free volume, (6) a number of valves and joints (fittings) which make up the interconnecting plumbing, and (7) a calibrated container for use in measuring the free volume. All of these items are deliverables. The major focus of this design task is to modify six canisters, prior to glass filling, in order to provide for linkage with the above system after glass filling. This linkage shall not involve welding or drilling. The modification of the canister shall be such that it does not interfere with normal operations.
