ronment, facilitate eventual decommissioning, and minimize, to the extent practicable, the generation of radioactive waste. The purpose of this regulatory guide is to present guidance that will assist applicants covered by 10 CFR 20.1406 in effectively implementing this licensing requirement. The guidance consists of specific design considerations drawn from nuclear industry experience and lessons learned from decommissioning. These have been combined to support the development of a contaminant management philosophy. The principles embodied in this philosophy are threefold: (1) prevention of unintended releases; (2) early detection, if there is unintended release of radioactive contamination; and (3) prompt assessment to support a timely and appropriate response. Applying these principles requires the use of sound design, proven engineering practices, conservative radiation protection principles, and attention to operational practices. All of this should be considered in the context of the life cycle of the facility from the early planning stages through the final plans for decommissioning and waste disposal. This guide describes some of the mechanisms that can be employed for facility life-cycle planning to meet the requirements of 10 CFR 20.1406. This regulatory guide contains information collection requirements covered by 10 CFR Parts 20, 30, 40, 50, 61, 70 and 72 that the Office of Management and Budget (OMB) approved under OMB control numbers 3150-0014, -0017, -0020, -0011, -0135, -0009 and -0132, respectively. The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number. RG 4.21, Page 3 B. DISCUSSION 1. Planning for Minimization of Contamination One of the significant early lessons learned about minimizing the radiological impacts of decommissioning was the importance of early planning for decommissioning.
