As for the uranium enrichment technology, it is worth mentioning
that the Uranium Enrichment Demonstration Plant (DP) operated
continuously for 13 years from 1988 to 2001. This plant, developed
and put into practical use by our country from scratch, terminated
its operation with its reliability confirmed. The accumulated
expertise obtained during its operation has been transferred to and
utilized by the uranium enrichment facility run by Japan Nuclear
Fuel Limited (JNFL) at Rokkasho-mura, Aomori Prefecture.
In recent years, development of technologies has been carried out
for related fields. Included among the fields are, recovery of
uranium remaining in piping or in the interior of the uranium
enrichment equipment, decontamination, volume reduction and
recycling of radioactive waste. Also, the gDecommissioning
Engineering Systemh has been developed to organize above-mentioned
technologies systematically.
Our projects have proceeded for as long as half a century since the
discovery of the uranium outcrop in November 1955, thanks to the
support and cooperation of local citizens and authorities. We,
Ningyo-toge Environmental Engineering Center, give safety our
highest priority and work hand in hand with the local citizens as in
the past.
Also, information disclosure is actively promoted for the
transparency of our projects.
