Agenda for Tiger Team telecon Tuesday July 17 1pm MDT, 2pm CDT, 3pm EDT (877)232-4392 passcode:540729 0. Review/Discussion of South Pole overall power issues for upcoming 2007 Season. This is well captured by the executive summary of Armstrong report. 1. Review/Discuss charge to the committee - Verify power requirements for winter 2007. (Use Armstrong report as basis and revalidate if needed.) - Living under 660 kW (700 kW) avg winter use. Develop options and identify associated challenges (Conservations, power shedding and power management) - Generating more power. Develop options and associated challenges (Generation and fuel storage and cargo) - Contingency planning if the fuel tanks are not left full at end of the season. 2. Review Armstrong report on current and future projections - Accuracy of 2006 and 2007 projections. Can we verify projections? - Understanding the problem by dealing with known +/- increments to current useage. (Make list of known +/- increments for 2007. 3. Review feedback from current winterovers. See report by Denis Barkats on SCOARA tiger team web page. 4. Develop options/suggestions for power conservation. What would it take to meet power demands with SPT and ICECUBE deployed? 5. Develop options/suggestions for generating more power. Run peaking generator / Add stand alone generator? - Fuel requirements - Effort to maintain a stand alone unit (staffing) - Transportation of fuel and storage? 6.

Owner: Carlton Walker. Date Due: 7/20/06 Update 7/12/06: Recent vendor contact for large capacity tanks for MCM indicated delivery of 5 to 7 weeks from date of approved drawings. A/I - RPSC will determine if an environmental evaluation to store additional fuel is needed. Owner: Bk Grant Date Due: 7/12/06. Update 7/12/06: Email back from RPSC EH&S stating, RPSC should feel comfortable to go forward and evaluate options for what is needed for fuel storage. Keep EH&S involved for input to ensure fuel storage includes secondary containment and other Environmental controls. RPSC EH&S has left a voicemail for Polly Penhale at NSF on this issue and is awaiting a response. --------------------------------------- Issues raised on SCOARA weekly telecon: --------------------------------------- Do we understand why the power useage was much lower after power outage? New station uses boilers to supplement heat if heat exchangers are insufficient to cover it. This uses fuel but not electrical generation. How much can be gained in fuel if sealed up better? Can we use smaller heating elements available in Galley for small jobs (min is 5 kw?) Liguid Nitrogen Plant issues and MAPO: First floor of MAPO needs the liquid nitrogen plant to keep above freezing. If nitrogen plant moves to cryo facilty, then MAPO Would perhaps need a bigger boiler, but definitely needs to be better sealed up and its HVAC upgraged. An inspection of MAPO revealed four main problems with cold leakage: 1. Viper hallway - could be sealed up at shop door. 2. Backdoor leaks (snow comes!) 3. DASI hallway is very lossy (Robert put foam on the floor) 4. DASI compressor room heated by cold hallway link to main building. Overall MAPO HVAC system needs a maintenance, also sealing up worn out seals, etc. AMANDA cools by drawing cold air through heated QUAD office area... Winterovers don't like the idea of transporting N2; already hard to transport liquid helium. Could we use more efficient nitrogen plant to save energy? SCOARA liquid cryogen working group is looking into this. Do we need all three helium re-liquidfiers 24/7/365? SCOARA liquid cryogen working group is looking into this. --------------- Useful numbers: --------------- 1 kw/year == 500 gallons; 13 kw hours == 1 gallon 1 gallon fuel =~ 1 gallon liquid nitrogen for current N2 plant $1 per kw hour at South Pole.
