Nuclear Criticality Safety Staff Resposibilities

DOE-STD-1158-2002

Do firefighters receive criticality safety training?

Are firefighters aware of any moderator-controlled areas or processes?

Are firefighters made aware of locations where a mist condition could affect criticality safety?

Criteria: Section 5.4, Operating Procedures

Are all fissile material handling operations performed according to approved procedures?

Are operations personnel or supervision involved in developing procedures?

Is there a mechanism to assure that only current, approved procedures, CSEs, and postings are

used for operations?

How does the line program supervisor know when to authorize work after all NCS requirements have

been met after modifications to the existing set of controls/procedures?

Does a clear, unambiguous link between the CSE, procedure and posting exist such that it is

traceable from floor level documentation?

Is there a mechanism to ensure that OSR related controls and requirements in procedures or

postings are not changed without proper analysis and approval?

Are Unreviewed Safety Question Determinations (USQD) performed for all procedure modifications?

Criteria: Section 5.5, Maintaining Compliance with Requirements

Are there procedures or mechanisms in place and effective to ensure that modifications to equipment

and/or processes results in a review of the applicable CSEs-procedure-posting set prior to

implementing the modification?

Are there documented surveillances or methods that ensure that new or modified operations conform

to applicable CSEs-procedures-postings?

Is there a process for ensuring that no new or modified operation is started until all applicable

verification steps have been performed which includes presence of approved CSEs, postings,

procedures and that no criticality infraction will result from startup?

Are appropriate surveillance frequencies established for engineered controls relied upon for criticality

safety to ensure that the controls are performing their intended function?

Criteria: Section 5.6, Labeling and Good Housekeeping Practices

Are stored, empty containers labeled as such where there could be uncertainty as to whether or not

containers are empty?

Are gloveboxes with criticality drains free of loose debris, which could potentially clog the drain?

Is fissile material stored in approved containers?

Prior to beginning work at a workstation, is there a procedure to verify compliance with criticality

safety requirements?

Is there evidence of fissile material holdup or filings in gloveboxes?

Are criticality drain liquid traps monitored for adequate liquid levels periodically?

3.0 NUCLEAR CRITICALITY SAFETY STAFF RESPONSIBILITIES

Criteria: Section 6.1, Technical Guidance for Design of Equipment and Processes
