7.2.3.3 Plans and Procedures

Facility nuclear criticality safety plans and procedures are important components of

the overall facility operation. These documents provide the means by which the

program is conducted and prescribe how nuclear criticality safety is to be achieved.

These plans and procedures identify how both the administrative activities are to occur

and how the technical aspects of nuclear criticality safety analysis are conducted. The

purpose of procedures is to facilitate the safe and efficient conduct of operations. The

processes of procedure development, review, training, and approval have sufficient

controls to ensure that nuclear criticality concerns are properly addressed. These

controls include the periodic review and reaffirmation of these procedures, ensuring

that procedure deviations are properly investigated and reported to facility

management and, if appropriate, to DOE. The controls should also mitigate the

possibility of such deviations recurring.

Procedures should exist that address the determination and posting of nuclear

criticality safety parameters. These procedures should include a description of how

the limits are to be determined and how workstations are to be posted as to form,

geometry controls, mass limits, moderator limits, etc.

Inspections and audits are performed to assess the success of the nuclear criticality

safety program. The audits must be performed by qualified individuals who are

independent of the operation. They are conducted to verify that operating procedures

and other safety standards are being followed and to identify any weaknesses in the

nuclear safety program. Deficiencies identified in these inspections and audits must

be formally addressed, tracked, reported, and resolved.

ANSI/ANS-8.20 (ANSI, 1991) provides guidance for development of nuclear

criticality safety training plans and procedures for personnel working with or near

fissile materials. This program and its associated procedures should describe the

program, training requirements, recordkeeping, content, responsibilities, and

objectives of a facility nuclear criticality safety program.

7.2.3.4 Nuclear Facility Safety Analysis

Safety analysis reports document the analysis and the potential consequences of

accidents and abnormal occurrences at nuclear facilities. For those facilities which

process, store, and handle plutonium and other fissile materials, nuclear criticality

safety analysis is a required element of the facility safety analysis report. The process

includes the identification of hazards in the facility (including nuclear criticality safety

hazards), the identification and development of potential scenarios involving nuclear
