Functional interfaces between safety system software components and the system-level

DOE-STD-1170-2003

Review a maintenance history file and discuss the potential implications of repeat

maintenance items.

Explain the intent of a Maintenance Problem Analysis Program and discuss a

maintenance problem where this program has been employed.

38.

Personnel shall demonstrate a working level knowledge of the functional

interfaces between safety system software components and the system-level

design.

Knowledge, Skills, and Abilities

Identify how system-level requirements are established and then assigned to

hardware, software, and human components of a digital instrumentation and

control system.

Identify the typical requirements that define functional interfaces between safety

system software components and the system -level design, as described in

standards such as ANSI/IEEE 830, IEEE Guide to Software Requirements

Specifications and IEEE 7-4.3.2, Standard Criteria for Digital Computers in Safety

Systems of Nuclear Power Generating Stations.

Identify the specific records that must be maintained and the requirements for

maintaining these records to document the development of safety system

software.

Review a development project for safety system software. Explain how the

functional interfaces between components and the system level design were

established and controlled.

39.

Personnel shall demonstrate a working level knowledge of the relationships

between the problems being addressed by safety analysis and design codes, the

design requirements for the codes, and the components of the codes.

Knowledge, Skills, and Abilities

Identify how functional requirements and applicability of safety analysis and

design computer codes are defined, documented, and controlled relative to

modeling and data assumptions, design constraints, sizing and timing conditions

and input/output parameters.

Review a development project for safety analysis or design software. Explain

how the problem being addressed by the software was translated into functional

requirements, how the requirements were established and controlled, and how

the code was reconciled with the original problem.
