PASI Proposals by April 15, 2001

The Department of Energy and the National Science Foundation (NSF) intend to support a limited number of Pan American Advanced Studies Institutes (PASI) modeled on the NATO Advanced Studies Institutes.  Pan American Advanced Studies Institutes are short courses of two to four weeks duration, involving lecturers of international standing at the advanced graduate and postgraduate level from the Americas. PASIs aim to disseminate advanced scientific knowledge and stimulate training and cooperation among researchers of the Americas in the basic sciences and engineering fields. Institutes in any physical or mathematical science discipline and/or engineering may be supported. Whenever feasible, an interdisciplinary approach is recommended.  Department of Energy, Office of Basic Energy Science contacts are:  Richard Kelley, SC-13, telephone: 301-903-9513, e-mail: richard.kelley@science.doe.gov and Don Freeburn, telephone: 301-903-3156, e-mail: don.freeburn@science.doe.gov.PASIs may involve up to 8 to 12 lecturers and approximately 40 to 50 students from the different countries in the Americas. A PASI award will cover expenses for the organization of the meeting, travel and living expenses of lecturers, and contribute to students' travel and living expenses. The principal investigator is responsible for (a) the preparation of the scientific program, (b) the selection of lecturers and students, (c) the administration of the meeting, and (d) the publication of lectures and proceedings from the meeting. The cost for any one Institute with a reasonable number of participants, including lecturers and students, is expected to range from $65,000 to $85,000, and may not exceed $100,000, aside from contributions from other sources.The NSF Division of International Programs will accept a number of proposals by April 15, 2001, to support such institutes.  Future deadlines will be February 15 of each year.   Individuals interested in submitting such a proposal should contact Eduardo Feller (efeller@nsf.gov) or Harold Stolberg (hstolber@nsf.gov) at 703-292-8710/8706 for additional information. This notice is also posted on the NSF web site at http://www.nsf.gov/sbe/int/americas/amnew.htm (Program Announcement NSF 01-48).

HFIR cooling tower replacement• Tower has been demolished and removed from the site• Sludge has been removed from the basin• New tower is under construction• Project is currently under budget and ahead of schedule

HFIR reflector replacement outage• Permanent reflector, semi-permanent reflector, and

pedestal/cage assembly completed and on site• Beam tubes and shutters required for the outage completed

(HB-2 in final fabrication)• Reactor has been disassembled to the reflector

HFIR reflector replacement, cooling tower, and experimental upgrades status

• Cooling tower replacement on schedule and within budget

• Cold source moderator vessel, new monochromator drums, shielding, and neutron guides in fabrication

• Major components (reflector, beam tubes, shutters) required for outage available

• Reactor disassembled to the reflector

• Outage work delayed ~ 4 months due to tritium issue

HFIR cooling tower construction 1/16/01

Discovered tritium contamination in a HFIR foundation drain in early October

Traced contamination to an underground process waste line and eliminated source of tritium contamination

EH review (Nov 28 - Dec 1) found no significant impact to worker safety or the environment

Defective underground process line will be replaced during the current outage

Tritium concentrations at HFIR drains and outfalls are decreasing and have not exceeded DOE or State action levels

Beryllium reflector outage activities have resumed

Instrument Status (ANL/ORNL)• First 3 instruments selected and incorporated into the project cost baseline; designs are underway

• Instrument costs are approximately double the estimates made in 1994, just prior to CD0. Cost increases result from experience with a new generation of pulsed spallation source instruments developed during the past 5 years at ISIS. These new instruments use (expensive) concepts that were not proven in 1994, such as large detector arrays and advanced neutron optics.

• Selected concepts for another 3 instruments.
