combined license
Combined license means a combined construction permit and operating license with conditions for a nuclear power facility issued pursuant to subpart C of this part.

early site permit
Early site permit means a Commission approval, issued pursuant to subpart A of this part, for a site or sites for one or more nuclear power facilities.

standard design
Standard design means a design which is sufficiently detailed and complete to support certification in accordance with subpart B of this part, and which is usable for a multiple number of units or at a multiple number of sites without reopening or repeating the review.

standard design certification
Standard design certification, design certification, or certification means a Commission approval, issued pursuant to subpart B of this part, of a standard design for a nuclear power facility. A design so approved may be referred to as a certified standard design.

All other terms in this part have the meaning set out in 10 CFR 50.2, or section 11 of the Atomic Energy Act, as applicable.

10CFR53   Energy
Part 53 is reserved.
no terms

10CFR54   Energy
Requirements for renewal of operating licenses for nuclear power plants.
current licensing basis
Current licensing basis (CLB) is the set of NRC requirements applicable to a specific plant and a licensee's written commitments for ensuring compliance with and operation within applicable NRC requirements and the plant-specific design basis (including all modifications and additions to such commitments over the life of the license) that are docketed and in effect. The CLB includes the NRC regulations contained in 10 CFR parts 2, 19, 20, 21, 26, 30, 40, 50, 51, 54, 55, 70, 72, 73, 100 and appendices thereto; orders; license conditions; exemptions; and technical specifications. It also includes the plant-specific design-basis information defined in 10 CFR 50.2 as documented in the most recent final safety analysis report (FSAR) as required by 10 CFR 50.71 and the licensee's commitments remaining in effect that were made in docketed licensing correspondence such as licensee responses to NRC bulletins, generic letters, and enforcement actions, as well as licensee commitments documented in NRC safety evaluations or licensee event reports.

integrated plant assessment
Integrated plant assessment (IPA) is a licensee assessment that demonstrates that a nuclear power plant facility's structures and components requiring aging management review in accordance with §54.21(a) for license renewal have been identified and that the effects of aging on the functionality of such structures and components will be managed to maintain the CLB such that there is an acceptable level of safety during the period of extended operation.

nuclear power plant
Nuclear power plant means a nuclear power facility of a type described in 10 CFR 50.21(b) or 50.22.

time-limited aging analyses
Time-limited aging analyses, for the purposes of this part, are those licensee calculations and analyses that:
     (1) Involve systems, structures, and components within the scope of license renewal, as delineated in §54.4(a);
     (2) Consider the effects of aging;
     (3) Involve time-limited assumptions defined by the current operating term, for example, 40 years;
     (4) Were determined to be relevant by the licensee in making a safety determination;
     (5) Involve conclusions or provide the basis for conclusions related to the capability of the system, structure, and component to perform its intended functions, as delineated in §54.4(b); and
     (6) Are contained or incorporated by reference in the CLB.
     (b) All other terms in this part have the same meanings as set out in 10 CFR 50.2 or Section 11 of the Atomic Energy Act, as applicable.

10CFR55   Energy
Operators’ licenses
Act means the Atomic Energy Act of 1954, including any amendments to the Act.

actively performing the functions of an operator or senior operator
Actively performing the functions of an operator or senior operator means that an individual has a position on the shift crew that requires the individual to be licensed as defined in the facility's technical specifications, and that the individual carries out and is responsible for the duties covered by that position.

Commission means the Nuclear Regulatory Commission or its duly authorized representatives.

Controls when used with respect to a nuclear reactor means apparatus and mechanisms the manipulation of which directly affects the reactivity or power level of the reactor.

Facility means any utilization facility as defined in part 50 of this chapter. In cases for which a license is issued for operation of two or more facilities, facility means all facilities identified in the license.

facility licensee
Facility licensee means an applicant for or holder of a license for a facility.

Licensee means an individual licensed operator or senior operator.

Operator means any individual licensed under this part to manipulate a control of a facility.

performance testing
Performance testing means testing conducted to verify a simulation facility's performance as compared to actual or predicted reference plant performance.

Physician means an individual licensed by a State or territory of the United States, the District of Columbia or the Commonwealth of Puerto Rico to dispense drugs in the practice of medicine.

plant-referenced simulator
Plant-referenced simulator means a simulator modeling the systems of the reference plant with which the operator interfaces in the control room, including operating consoles, and which permits use of the reference plant's procedures.

reference plant
Reference plant means the specific nuclear power plant from which a simulation facility's control room configuration, system control arrangement, and design data are derived.

senior operator
Senior operator means any individual licensed under this part to manipulate the controls of a facility and to direct the licensed activities of licensed operators.

simulation facility
Simulation facility means one or more of the following components, alone or in combination: used for either the partial conduct of operating tests for operators, senior operators, and license applicants, or to establish on-the-job training and experience prerequisites for operator license eligibility:
     (1) A plant-referenced simulator;
     (2) A Commission-approved simulator under §55.46(b); or
     (3) Another simulation device, including part-task and limited scope simulation devices, approved under §55.46(b).

systems approach to training
Systems approach to training means a training program that includes the following five elements:
     (1) Systematic analysis of the jobs to be performed.
     (2) Learning objectives derived from the analysis which describe desired performance after training.
