DOE-STD-1027-92

Purpose

The purpose of this DOE Standard is to establish guidance for the preparation and review of

hazard categorization and accident analyses techniques as required in DOE Order 5480.23,

Nuclear Safety Analysis Reports. This new Order requires further guidance to ensure

consistency across all nuclear facilities within the DOE complex. This DOE Standard imposes

no new requirements on nuclear facilities. Instead, it focuses on (1) the definition of the

standard identifying nuclear facilities required to have SARs in order to comply with the Order,

(2) the SAR implementation plan and schedule, (3) the hazard categorization methodology to be

applied to all facilities, and (4) the accident analysis techniques appropriate for the graded

approach addressed in the Order. DOE Order 5480.23 and its attached guidance document

provide some direction on the use of the graded approach. This report is intended not to

supersede that direction, but to supplement and clarify it. Methods other than those suggested

in this guide may be considered for applying the graded approach, but they must be justified

whenever grading is applied.

Applicability/Scope

This DOE Standard is to be used with DOE Order 5480.23 and may not be applicable to other

DOE Orders. Regarding the applicability of other nuclear safety Orders to those facilities

which fall below category 3 criteria, as defined by this standard, the PSOs shall provide

guidance, as appropriate.

Developed by a working group with contributions from all Secretarial and oversight

organizations having nuclear safety responsibilities, with input from several field and

contractor organizations, and with clarifying direction from the Senior Nuclear Managers

meeting of October 26, 1992, this standard applies to DOE nuclear facilities as defined in the

Order and is suitable for DOE nuclear facilities.

Background and Format

The Department of Energy (DOE) has the responsibility to establish rules, regulations, and

Orders as necessary to protect health or to minimize danger to life or property. In carrying

out this responsibility, DOE has issued Order 5480.23, Nuclear Safety Analysis Reports.

This Order specifies requirements for safety analyses involving DOE nuclear facilities, and

for submittal, review, and approval of contractor plans and programs to meet these

requirements.

This document provides specific guidance on several of the requirements contained in this Order.

Section 1 establishes the threshold quantities of hazardous materials which, if exceeded, would

mandate the development of a SAR under this Order. Section 2 discusses the SAR upgrade plan

and schedule which must to be submitted to each PSO. Section 3 provides a uniform
