A P P L I C A T I O N O F T H E G R A D E D A P P R O A C H . Discussion is limited to

those areas in which human performance plays an important role in ensuring the

performance of safety SSCs. The preparer of the DSA will present information at a level

that is considered sufficient for the review and approval of the DSA.

Hazard Category 2 facilities may have human- machine interfaces with safety-class SSCs

and safety-significant SSCs. Hazard Category 3 facilities do not have safety-class SSCs

but may have human- machine interfaces with safety-significant SSCs. Discussions

pertain only to the human- machine interfaces with safety SSCs and in proportion to the

importance of those human-machine interfaces to the performance of those safety SSCs.

To meet the human factors safety requirements of 10 CFR 830, a systematic inquiry of

human factors must be presented. An inexpensive yet effective method for accomplishing

this is through application of basic human factors checklists. Such checklists typically

examine preparation, validation, and use of written procedures; qualification and training

of operating crews; staffing; design of the human- machine interfaces; and allocation of

control functions to workers versus automatic devices. Although application of a

checklist is not a requirement, implementation of such a checklist will satisfy the

documentation requirements associated with systematic inquiry into human factors.

Discussions can be brief and are limited to summaries of the major features of the

systematic inquiry.

13.1 INTRODUCTION

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

graded approach and include s objectives and scope specific to the chapter as

developed.

13.2 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.

13.3 HUMAN FACTORS PROCESS

This section summarizes the human factors process for systematically evaluating

the importance of human factors in facility safety. This summary includes the

process features to provide assurance that the importance of human- machine

interfaces is considered in facility safety.
