Description / Abstract:
VISION STATEMENT AND OVERVIEW
The ASME Board on Nuclear Codes and Standards approved an effort
to develop rules for the construction of fusion-energy-related
components such as the vacuum vessel (vacuum or target chamber),
cryostat and superconductor structures and their interaction with
each other. These rules will be found in a new Division 4 of
Section III entitled "Fusion Energy Devices". The rules shall
contain requirements for materials, design, fabrication, testing,
examination, inspection, certification, and stamping. The formation
of the new Subgroup on Fusion Energy Devices will be responsible
for the development of these rules and has begun to develop its
membership and future working group support structures.
Current ASME BPVC Section III code rules do not specifically
address the construction rules for fusion energy devices that are
currently under consideration, nor do they support on-going
projects, such as ITER (Tokamak Concept) and other fusion concepts
such as Inertial Confinement Fusion (primarily laser fusion; an
example is the National Ignition Facility).
While it may be feasible to modify the existing Section III
rules to meet future fusion needs, it has been recommended that a
complete separate set of rules be developed for these new fusion
energy devices to cover design, construction and
inspection/testing. In addition, it is anticipated that operation
and maintenance requirements for these fusion energy devices may
also require a new set of rules or major modifications to the
existing ASME Operations and Maintenance (OM) Code. It is necessary
that these new rules contain the best available methods and
technology in each area.
As such, this Roadmap for the Development of ASME Code Rules
for Fusion Energy Devices (FED Roadmap) was developed to
outline what should be considered when developing these rules. The
approach in this FED Roadmap consists of a compilation of
suggestions from subject matter experts and organizations
interviewed, as well as that of the author. As the project teams,
task groups, and committees deliberate, it is anticipated that some
of the tasks identified in this FED Roadmap will be revised or
eliminated from consideration and others will be added.
The Fusion Energy Device Code rules will be developed by various
project teams within the Subgroup Fusion Energy Devices of the BPV
Committee on Construction of Nuclear Facility Components (III) and
will be coordinated with other impacted groups both inside and
outside ASME. A Stakeholder Task Group reporting to the Chairman of
the BPV Committee on Construction of Nuclear Facility Components
(III) and the Chairman of the Subgroup Fusion Energy Devices has
been formed to identify stakeholders and their needs, and develop
recommendations and approaches to be incorporated into new FED Code
rules.
