Content Guidance for Sections of Chapter 6

CONTENT GUIDANCE FOR SECTIONS OF CHAPTER 6

6.1

INTRODUCTION

This section provides an introduction to the contents of this chapter based on the

graded approach and includes objectives and scope specific to the chapter as

developed.

6.2

REQUIREMENTS

This section lists the design codes, standards, regulations, and DOE Orders that are

required for establishing the safety basis of the facility. The intent is to provide

only the requirements that are specific for this chapter and pertinent to the safety

analysis, and not a comprehensive listing of all industrial standards or codes or

criteria. SRIDs may be referenced as appropriate.

6.3

CRITICALITY CONCERNS

This section identifies the fissile material available within the facility and provides

information on the location of potential criticality hazards (e.g., description, and

drawing), the fissile material form (e.g., chemical and/or physical, including

isotopic content, concentration, densities), and the maximum quantities involved.

This information should be summarized from Chapter 3, "Hazard and Accident

Analyses."

6.4

CRITICALITY CONTROLS

This section summarizes information relevant to criticality control. Include a

general discussion of the criticality safety design limits, their bases, and any design

criteria used to ensure subcritical configurations under all normal, abnormal, and

accident conditions (i.e., ensure criticality limits are not exceeded); the parameters

used for the prevention and control of criticality and the methods for the application

and validation of these parameters; and the application of the double contingency

principle in criticality safety. It is not the intention of this section to individually

list all criticality safety design limits.

6.4.1

Engineering Controls

This section summarizes the safety design limits on engineered controls, either

passive or active, and the bases placed on equipment designs or operations to

ensure subcritical conditions under all normal, abnormal, and accident

conditions. Include in the summary of these engineered controls use of

geometry, spacing, and any other engineered controls (e.g., neutron absorbers,

elimination of moderators, storage location limitations, and level detectors).

This section also summarizes the configuration control program as it relates to
