17 DECOMMISSIONING AN) POSSESSION-ONLY
LICENSE AMENDMENTS
This chapter contains guidance for evaluating decommissioning plans (DPs),
requests for license termination, and applications for possession-only license
amendments for non-power reactors. These applications are submitted by nonpower
reactor licensees who wish to terminate operations and decommission their
facilities.
During the past 54 years, many non-power reactors, critical facilities, and specialpurpose
reactors have been dismantled, decontaminated, decommissioned, and
released for unrestricted use. In the absence of detailed regulations governing.
decommissioning, NRC has developed a systematic approach for licensee and
NRC actions to terminate facility licenses [American National Standards
Institute/AmericanNuclear Society (ANSI/ANS) 15.1-1981 and NRC 'Guidance
and Discussion of Requirements for an Application To Terminate a Non-Power
Reactor Facility Operating License]. Among these actions are issuance of
possession-only license amendments and orders authorizing facility dismantlement.
On June 27, i988, NRC published a notice of rulemaking (53 FR 24018) amending
its regulations. These amendments affected the decommissioning of licensed
reactor acilities. The amended regulations broaden the requirements leading to
license termination, but do not change the charamteristics of possession-only
license amendments. The reviewer should be aware that additional changes have
been proposed to the decommissioning regulations (see 60 FR 37374). Therefore,
the following guidance is offered in the interim to facilitate the review of
decommissioning activities during this period.
Because not all licensees request a possession-only license amendment before
submitting a DP and a request for terminating the license, DPs and applications for
a possession-only license amendment are treated separately in this review'plan.
17.1 Decommissioning_
17.1.1- Preliminary Decommissioning Plan
In addition to theDP required by IO CFR 50.82, 10 CFR'50.75(f) requres each
licensee to submit a preiminary DP. The preliminary DP shall be submitted at or
about 5 years before the'projected end of operation.: The DP shall contain an
estimate of the cost of decommissioning and an up-to-date assessment of the major
technical factors that could affect planning for decommissioning.- The licensee
shall consider the following factors when assenibling this information:
