Standard Guide for Post-Deactivation Surveillance and Maintenance of Radiologically Contaminated Facilities
SIGNIFICANCE AND USE
The purpose of this guide is to provide the user information and guidance for preparation of a plan for the surveillance and maintenance of nuclear facilities that have been deactivated and are awaiting D&D.
This document provides guidance for performing S&M in a way that will ensure worker and public safety, while also addressing stakeholder requirements.
Use of this guide helps standardize the basic requirements for S&M of nuclear facilities.
Use of this guide helps ensure that the S&M plan addresses the significant activities and actions necessary to maintain these facilities in a safe and stable condition until they can be decommissioned.
SCOPE
1.1 This guide outlines a method for developing a Surveillance and Maintenance (S&M) plan for inactive nuclear facilities. It describes the steps and activities necessary to prevent loss or release of radioactive or hazardous materials, and to minimize physical risks between the deactivation phase and the start of facility decontamination and decommissioning (D&D).
1.2 The primary concerns for S&M are related to (1) animal intrusion, (2) structural integrity degradation, (3) water in-leakage, (4) contamination migration, (5) unauthorized personnel entry, and (6) theft/intrusion. This document is intended to serve as a guide only, and is not intended to modify existing regulations.

3. Terminology
3.1 Definitions:
3.1.1 deactivation—to remove a facility from service. Deactivation means the facility is placed in a safe and stable condition.
3.1.2 decommission—to remove a nuclear facility safely from service and reduce residual radioactivity and other hazardous
materials to levels that permit release of the property or facility for unrestricted use and termination of any applicable license(s).
3.1.3 decontamination—those activities employed to reduce the levels of radioactive and hazardous contamination in or on
structures, equipment, and materials.
3.1.4 nuclear facility—a facility whose operations involve (or involved) radioactive materials in such form or quantity that
radiological controls are (or were) required to protect employees, the environment, or the general public.
3.1.4.1 Discussion—Included are facilities that are (or were) used to produce, process, use, or store radioactive materials. Some
examples are nuclear reactors (power, test, or research), fuel fabrication plants, fuel reprocessing plants, uranium/thorium mills,
Uranium Hexaflouride (UF-6) production and enrichment plants, research laboratories using radioactive materials, chemical
processing facilities, and radioactive waste disposal sites.
3.1.5 standby—a condition in which a nuclear facility has been deactivated, but in such a way that it could be restarted for its
original purpose.
3.1.5.1 Discussion—Critical systems are maintained in working order with regularly scheduled maintenance activities
performed. Surveillance and Maintenance (S&M) requirements for facilities placed in standby are much more demanding than for
those which are deactivated for planned decommissioning. Operations procedures are usually maintained for facilities placed in
standby.
3.1.6 S&M—the act of performing periodic inspections, and related maintenance activities on facilities which have been
deactivated and are awaiting the start of decommissioning.
4. Significance and Use
