Neutron Sciences 2008 Annual Report - 17.79 MB - Spallation ...

High Flux Isotope Reactor
Fiscal year 2008 was
highly productive
for HFIR operations
and marked the first
full year of operation
with the cold neutron
source and a new suite
of scientific instruments.
By the end of
the fiscal year, we had
› Operated for 3550
hours, or slightly
more than six
cycles.
› Irradiated materials
to provide
isotopes for medical
research and
commercial uses
and to provide data for fusion reactor design.
› Irradiated and analyzed 221 samples in the
HFIR Neutron Activation Analysis Facility in
support of nuclear nonproliferation work, forensics
studies for criminal investigations, special
radioactive source production, reactor materials
dedication, and basic science.
› Improved and upgraded HFIR for reliable, sustained
operation, including refurbishment of two
of its four main coolant pumps, electrical distribution
system upgrades, reactor temperature
control system upgrades, and building heating
and air conditioning system improvements.
ABOUT US 2008 ANNUAL REPORT
Users Hiroshi Kagayama (left) of Kyoto
University and Masakazu Nishi (right) of
the University of Tokyo analyze data at the
Polarized Triple-Axis Spectrometer at HFIR.
The planned operations for fiscal year 2009 will be
similar to 2008, with a tentative schedule of 140
operating days provided over six operating cycles.
Steady-state operation will eventually provide neutron
beams and irradiation services for eight to ten
reactor cycles per year. With regular operation, the
next anticipated major shutdown—for a beryllium
reflector replacement—will not be necessary until
after 2020.
