endorsed this self-assessment tool prior to the August 1999 Workshop. The Deputy Secretary of

Energy subsequently required all DOE sites to self-assess their criticality safety programs using

these criteria in response to the Tokai-Mura criticality accident.

The applicable DOE Order for criticality safety is DOE Order 420.1. It requires compliance with

certain ANSI/ANS Standards for criticality safety. The assessment areas presented in this plan

were drawn from the mandatory Standard, ANSI/ANS-8.19-1996, Administrative Practices for

Nuclear Criticality Safety, and are categorized as follows:

Management Responsibilities - Management demonstrates ownership and participation in

the criticality safety program; authorities and responsibilities are defined, understood and

implemented; management provides a nuclear criticality safety staff that is competent in the

physics of criticality and associated safety practices as well as familiar with fissile material

operations; management ensures that the nuclear criticality safety staff is independent of

line management to the extent practicable; management assigns responsibility for criticality

safety in a manner consistent with other safety disciplines; and, management establishes

means of monitoring the criticality safety program and obtains feedback on the overall

effectiveness of the program.

Supervisory Responsibilities - Line supervision accepts responsibility for the criticality safety

of their operations; supervisors understand the controls, contingencies, and criticality safety

basis for operations under their control; classroom and job-specific training in criticality

safety is provided to personnel; procedures govern all work and there are effective change

control and configuration control mechanisms; supervisors verify compliance with criticality

safety specifications before authorizing work; and supervisors require conformance with

good safety practices, good housekeeping, and unambiguous identification of fissile

materials.

Nuclear Criticality Safety Staff Responsibilities - The nuclear criticality safety staff is

comprised of specialists skilled in the techniques of nuclear criticality safety assessment and

familiar with plant operations while, to the extent practicable, administratively independent of

line management; the staff provides technical guidance for design of equipment, processes,

and procedures; the staff reviews modifications to equipment, process, and procedures

involving fissile material; the staff maintains familiarity with criticality codes, guides,
