FOREWORD

Two standards have been developed that pertain to the safety of fusion facilities. These are DOE-

STD-6002-96, Safety of Magnetic Fusion Facilities: Requirements , and DOE-STD-6003-96, Safety

of Magnetic Fusion Facilities: Guidance . The first of these standards identifies requirements that

subscribers to that standard must meet to achieve safety in fusion facilities. The second standard

contains guidance to assist in meeting the requirements identified in the first. This handbook provides

additional documentation on good operations and design practices as well as lessons learned from the

experiences of designers and operators of previous fusion facilities and related systems. It is intended

to capture the experience gained in the various fields and pass it on to designers of future fusion

facilities as a means of enhancing success and safety.

The sections of this document are presented according to the physical location of the major systems

of a fusion facility, beginning with the vacuum vessel and proceeding to those systems and

components outside the vacuum vessel (the "Ex-vessel Systems"). The last section describes

administrative procedures that cannot be localized to specific components. It has been tacitly

assumed that the general structure of the fusion facilities addressed is that of a tokamak, though the

same principles would apply to other magnetic confinement options.

In what follows, use of the term "shall"has been avoided because this document is intended as advice

and guidance only. It is not to be construed as regulatory in any way. In a similar vein, references

to: safety-class or safety-significant structures, subsystems, and components should be viewed with

the understanding that use of these designations, though not mandatory in the Requirements standard

(DOE-STD-6002-96), are recommended in the Guidance standard (DOE-STD-6003-96). Again, the

content of this document represents accumulated conventional wisdom of those who have experience

building such systems and facilities.

The material here is collected from a wide variety of sources. With the intent of capturing the

information rather than making the product a polished document, there will be some variations in style

and approach evident in the various sections. The authors felt allowing these variations would be a

good stewardship of resources in the times of fiscal restraint and uncertainty in which this document

was prepared.
