Relationship Between the Two Standards

restoration. Relevant experience should be drawn from all applicable areas within the

DOE community in developing the needed guidance.

Accordingly, the basic intent of this set of Standards is to more clearly identify design

and operational safety requirements for fusion facilities and to provide guidance in

meeting those requirements. These Standards reflect recognition of the differences

between fusion facilities and other facilities.

2. Relationship Between the Two Standards. Two Standards have been produced. The

first, DOE-STD-6002-96, Safety of Magnetic Fusion Facilities: Requirements, is a

summary of requirements relative to safety of magnetic fusion facilities. With two

exceptions, requirements presented there come from CFRs, national consensus

standards, or best available information from recognized authoritative institutions

implemented within a fusion context. The exceptions, addressed in following para-

graphs, come from community consensus and the best judgment of the Fusion

Safety Steering Committee, charged with the responsibility of preparing these

documents.

The requirements, in DOE-STD-6002-96, convey a set of rules for use by owners,

managers, designers, and operators of a fusion facility to establish its design and

operating envelope to ensure that workers, the public, and the environment are pro-

tected from the facility's hazards. Capital investment protection was not a specific

goal of the requirements document. Because of the range of fusion facilities that may

come under the purview of this Standard and their differing hazards, the Standard

was not written to be prescriptive. It states what must be done, but not how. This

approach gives designers flexibility, but it also puts the burden on them to determine

how to implement the requirements for the specific facility. Furthermore, the use of

risk-informed prioritization or graded approach is recommended in meeting the

requirements.

DOE-STD-6003-96, Safety of Magnetic Fusion Facilities: Guidance is, as the name

indicates, guidance on how to achieve or implement the requirements set forth in the

Requirements Standard, DOE-STD-6002-96, assuming DOE regulation for an

engineering scale facility like ITER. Nothing in the guidance volume is intended to

add to the requirements, only to indicate methods and processes that may be used

to meet existing requirements. In that sense, it is subordinate to DOE-STD-6002-96.

The guidance provides an acceptable but not necessarily unique way to implement

the requirements for an experimental fusion facility such as ITER or DEMO. This

guidance would presumably be updated for eventual fusion power reactors, where

results from preceding experimental devices would resolve outstanding material,

plasma physics, and fusion technology issues that the present guidance document

has to accommodate.
