Applicability - DOE-STD-1120-1-20050011

DOE-STD-1120-2005/Vol. 1

1.2

Applicability

Volume One of this Standard applies to hazard category 2 or 3 environmental restoration

activities and decommissioning projects as defined in 10 CFR 830, Subpart B. Volume One

does not apply to facility life-cycles that are subject to the safe harbor provisions of DOE-STD-

3009, Preparation Guide for U.S. Department of Energy Nonreactor Nuclear Facility Safety

Analysis Reports or DOE-STD-3011, Guidance for Preparation of Basis for Interim Operation

(BIO) Documents (i.e., deactivation including material stabilization campaigns such as

processing of reactive liquids and any long-term surveillance and maintenance). Since Volume

Two has a broader focus than safety basis requirements it does apply to all phases of facility

disposition (i.e., facility deactivation, surveillance and maintenance, and decommissioning).

1.3

Organization

The Standard consists of two volumes. Volume 1: Documented Safety Analysis for

Decommissioning and Environmental Restoration Projects, has four sections, including this

introductory section. Section 2 discusses general safety basis concepts that have a direct or

indirect impact on the DSA. Section 3 provides guidance on preparing DSAs and TSRs that are

compliant with 10 CFR 830, Subpart B requirements and associated methodology for

decommissioning of a nuclear facility. Section 4 provides guidance on preparing DSAs and

TSRs that are compliant with 10 CFR 830, Subpart B requirements and associated methodology

for environmental restoration activities involving work not performed within a permanent

structure.

Volume 2: Appendices, complements other sections of the Standard with additional

environment, safety and health (ES&H) information. Appendix A provides a set of candidate

DOE ES&H directives and external regulations, organized by hazard types that may be used to

identify potentially applicable directives to a specific facility disposition activity. Appendix B

offers examples and lessons learned that illustrate implementation of ES&H approaches

discussed in Section 3 of Volume 1. Appendix C contains Integrated Safety Management

guidance that applies to all facility disposition projects. Appendix D provides supplemental

safety basis guidance related to inactive waste sites. Appendix E provides example risk binning

guidelines that can be used to support control selection. Appendix F provides guidance for

readiness evaluations.
