Simulator Status
• Mechanical assembly of the simulator completed early April 2000
• Characterization on-going :– sub-system performance– air flow capacity (mass versus temperature)– fire scenario sensitivities (spray and pool)
• Planning the first trial of the MPSE– the first "iteration" will be performed with HFC-125
• HFC-125 is plentiful on-site• CF3I will be the first agent run against the full MPSE
– only one robust fire cycle will be run– performing this trial to "bug-out" procedures

Simulator Status
• Activities in the near future :
– 9May00 => distribution trial; MPSE step I• Expect 3-5 days to smooth procedure out and attain goal• HFC-125 simulation will be used to indicate an acceptable profile• Halon 1301 will be discharged to verify the results of the simulant effort
– 16May00 => robust fire search; MPSE step II• Planning 5 days minimum to attain goal• Expecting difficulty in finding the "right fire"
– ??May00 => replacement fire challenge; MPSE step III• Planning 5 days minimum to attain goal• Expecting difficulty in quantifying the mass needed to succeed
– ? => Quantify concentration with analyzer; MPSE step IV• 1 day to perform• simplest part of the process
– ? => begin full MPSE procedure for CF3I
