ESTABLISHING THE BASES FOR PROCEDURES

Because procedures are a critical element of maintaining a safety envelope, they must be

based on the same facility design bases, design verification and functional test results,

safety analyses, and operating limits and surveillance requirements used to establish the

safety envelope. There are at least three pertinent bases to consider for the development

of the technical procedure, the management control basis, technical basis, and design

basis.

The technical basis of a technical procedure is a compilation of information such as the

Safety Analysis Report, Technical Safety Requirements, operational "lessons learned",

facility configuration, and conditions of performance. The technical basis documentation

is needed to describe the technical parameters and boundaries within which the process is

performed.

The management control basis of a technical procedure contains information such as

management controls on the process, facility administrative requirements, and relevant

management plans and programs.

The design basis of a technical procedure includes the design criteria, vendors, and

engineering standards drawings and specifications that were used in the design and

construction of the facility.

The process of establishing the bases involves activities used to research and plan the

content of a procedure. The bases of a procedure must be defined before the actual writing

can begin. The procedure writer develops procedure bases by either updating the bases of

a current procedure or creating bases for a new procedure. The bases provide a

researched compilation and analysis of the engineering and design, safety, operations,

regulatory, vendor, and administrative information necessary to develop a comprehensive

and usable procedure. They are based on the facility as-built drawings, lessons learned,

test information, administrative and management controls, and other relevant information.

The bases are working documents and are part of the Procedure History File (PHF). The

PHF is compilation of all pertinent information used to develop the procedure and any

subsequent revisions. The bases are used to analyze the requirements that must be

included in a procedure or revision. The contents of the bases may be revised during

procedure preparation to ensure that the final product contains accurate and relevant

information.

All the bases combined are referred to as the procedural basis. The procedural basis is

used for:
