ALSACE
STRASBOURG
- UNIVERSITY REACTOR
-- shut down
Purpose: experimental
irradiation and production of short-lived radioisotopes
Type: argonaut reactor
Location: Université Louis Pasteur in Strasbourg (Bas-Rhin)
Operator: Service du réacteur nucléaire universitaire
Period
of operation:
1966-1997
Power: 0.1 MW thermal
Fuel: uranium enriched
to 93 percent (minimal critical mass: 4.80 kg)
The reactor stopped operating at the end of 1997. The DSIN authorized the
unloading of fuel from the core March 17, 2000. The fuel was sent to La Hague in
December 2000 [DSIN 00, Andra 06]. The
control bars were removed from the reactor in May-June 2002. Authorization to undertake definitive
shutdown and dismantling was published in the Journal officiel 22 February 2006. Dismantling began in the second half of
2006 and ended in August 2008 [ASN 06 and 08]. The building is to be used for teaching and
research that does not involve the handling of radioactive materials
[www.sfen.org, ix 06].
Stored at the site as of May 2005, were five control bars (0.007 t--5 GBq); graphite plugs (0.075 t—10 MBq),
a graphite reflector (2 t—<1 GBq) and additional
waste from dismantling; technological wastes; and a neutron source (37 GBq) awaiting transfer to CEA Valhro. Technological wastes are transferred to Andra through the Strasbourg Institute of Research on
Subatomic Particles (IN2P3) [Andra 06].
