Facility Decommissioning,
Final Status Survey, and License Termination
Work Description
– General:
Chase Environmental Group
(Chase) was contracted by Cimarron Corporation, a subsidiary
of Kerr-McGee Corporation, to develop planning documents
for closure of their 840 acre nuclear fuel fabrication facility
near Cimarron, OK. The facility had several radioactively
contaminated process and storage buildings, waste water
ponds, sanitary lagoons, an incinerator, and waste disposal
areas. A comprehensive system of underground utilities and
drains was located at the facility.
Chase has provided long-term
planning and regulatory liaison services for Kerr-McGee
Corporation since 1993. Since then, Chase has prepared the
Radiological Characterization Report and the facility’s
Decommissioning Plan. Additionally, Chase has authored three
Final Status Survey Plans in accordance with NUREG/CR-5849
and eight Final Status Survey Reports for submission to
the U.S. Nuclear Regulatory Commission. Chase has been the
principal technical support contractor for Cimarron in developing
these documents. These reports and plans have required detailed
analysis of environmental monitoring data, contaminant plume
modeling for groundwater, developing and reviewing health
and safety plans, participating in ALARA committee meetings,
and providing quality assurance and radiological controls
program support.
To date, the decommissioning
process has resulted in releasing approximately 700 acres
of the site from U.S. Nuclear Regulatory Commission licensing
control. Notably, Chase authored the only Subsurface Final
Status Survey Plan and Report ever approved by the U. S.
Nuclear Regulatory Commission.
