Description
In any irradiation facility, upgrading of $^{60}$Co activity is
one of the most important maintenance operations, which should be done
periodically to maintain the dose rate in the irradiation process
given the decay of $^{60}$Co. In general there are two kinds
of irradiator with either wet storage or dry storage
of $^{60}$Co in the facility.
For wet storage facilities, the $^{60}$Co upgrade receives the
cobalt in a supplier provided shipping container and the source is
transferred into the pool of the facility to the source rake of the
irradiators.
For dry storage, cobalt upgrade is done at the supplier facility by
shipping the entire cobalt irradiation container, which serves also as
transport container, back to the supplier to upgrade the
source $^{60}$Co.
The Station d’ionisation de Boukhalef (SIBO), is a panoramic
irradiator with dry storage of $^{60}$Co in a container which
is also used as the transport container in the first loading. We have
been faced with a problem of the container transport and we need to
find a solution to upgrade the $^{60}$Co. Our proposed
solution is to bring cobalt in a supplier container and transferring
the new sources to our facility container using a temporary pool
fabricated in the facility.
The objective of this paper is to show a case study experience. This
operation has been considered as a success story by the IAEA and
opened this solution method for similar irradiators in other countries
which have the same problem. Its execution was a real application of
the nuclear security system installed in the facility and during the
transport of $^{60}$Co.
