Class 1, 2, 3 & MC Components;
Supports; Core Support Structures;
and Class 1 Components in Elevated
Temperature Service
6
Division 1 Initiatives (1 of 8)
ASME commissioned a project under ASME
S&T LLC to develop an SMR roadmap
• Draft report is undergoing peer review
• Target: issue SMR roadmap by end of June 2014.
• Implement actionable items – To Be Determined
7
Division 1 Initiatives (2 of 8)
ASME develops the Nuclear Code of the future with an
initial target publication date of June 2025
An early draft vision statement for this objective is:
“A simplified Code that recognizes and utilizes modern
construction methodology, governs the complete
lifecycle of the component or system, maintains
appropriate margins of safety, invokes performance
based value added requirements and provides separate
administrative and technical requirements.”
8
Division 1 Initiatives (2 of 8)
ASME develops the Nuclear Code of the future
with an initial target publication date of June 2025
– target dates:
• Vision and Concept Development – end of CY
2015
• Content Development – Summer of CY 2024
• Governance Development – end of CY 2017 and
reaffirmed Spring of CY 2023
9
Division 1 Initiatives (3 of 8)
• Establish rules for repair of components that
support needs of newly constructed plants like
Watts Bar 2 and new plant construction (with
emphasis on those licensed to 10CFR Part 52),
including modular construction
– BPV III forms a Task Group on Component Repair
– Issue Code Cases or revisions to BPV III that
establish rules for repair of components
10
Division 1 Initiatives (4 of 8)
Develop rules to allow for construction of larger
components prior to identification of an Owner
• Revise NCA-3256(b) to eliminate the restrictions
imposed by that paragraph for construction of items
prior to Owner involvement.
• C&S Connect record 13-1783 has been created and the
background document for this proposed change is out
for review.
11
Division 1 Initiatives (5 of 8)
Develop Sec. III Appendix for the design and
fabrication of high density polyethylene (HDPE)
pipe
• Appendix has been developed is out for ballot at BPV
III (14-1440).
• Target publication in the 2015 Code.
• Regulator acceptance via 10CFR50.55a in 2017
(tentative, based on regulator schedule).
12
Division 1 Initiatives (6 of 8)
Update existing Rules for Impactive and Impulsive
Loads.
• Develop a proposed code change to update existing
rules.
• Target publish Phase 1 rules in a Code Case by the end
of 2015
13
Division 1 Initiatives (7 of 8)
Revise Registered Professional Engineer
jurisdictional requirements to eliminate as a barrier
to global application of BPV III.
• June 2014 Code Week – Joint BPV III/TOMC TG
reached consensus opinion and approval to prepare
Code Revisions for affected standards
• Target: Code Cases or revisions to BPV III that
implement consensus opinion approved and published
by June 2016
14
Division 1 Initiatives (8 of 8)
Simplify the code by eliminating content that is
duplicated in various Code books.
• Completion of two ongoing consolidation activities in
Subgroup Component Design:
– 10-1381 Consolidation of Design-by-Analysis
– 13-932 Consolidation of Design-by-Rule for Vessels
• Target: publication in the 2017 Edition
15
Division 2 Initiatives
Concrete
Containments
16
Division 2 Initiatives (1 of 2)
Obtain NRC Endorsement of the 2013 Edition of
Section III, Division 2.
• The NRC has agreed that Division 2 Regulatory Guides
will be updated and will reference a more recent Edition
of the Division 2 Code
• Target: will be accomplished based on the NRC
schedule for updating Reg. Guides.
17
Division 2 Initiatives (2 of 2)
Develop Rules for beyond design basis accidents
specifically for the evaluation of impactive and
impulsive loadings.
• Develop funding for testing of impactive loading effects
on concrete containments.
• Target: obtain funding for Phase I testing by the end of
2015
18
Division 3 Initiatives
Containments for Transportation
and Storage of Spent Nuclear
Fuel and High Level Radioactive
Material and Waste
19
Division 3 Initiatives (1 of 3)
Achieve U.S. Nuclear Regulatory Commission
(NRC) endorsement of Section IIII, Division 3.
• NRC is completing review of Div 3 and will provide
review comments to Division 3 committees for
discussion and clarification.
• Target: 2017 Edition has been established for
publishing necessary revisions in order to satisfy NRC
review comments.
20
Division 3 Initiatives (2 of 3)
Develop Rules for beyond design basis accidents
specifically for the evaluation of impactive and
impulsive loadings.
• Develop funding for testing of impactive loading effects
on concrete containments.
• Target: obtain funding for Phase I testing by the end of
2015
21
Division 3 Initiatives (3 of 3)
Publish new Subsection WD, construction rules for
internal support structures (or baskets) for use in
storage or transportation containments, or both.
• A draft has been submitted to the BPV III for approval.
• However, Division 3 General Requirements
(Subsection WA) also need revision and final approval
before this new subsection can be published.
• Target: publication in 2017 Edition
22
Division 4 Initiatives
Fusion Energy Devices
(in development)
23
Division 4 Initiatives (1 of 4)
Issuance of ASME III Division 4.
• Target: publication of first section of fusion codes rules
in 2015 Edition
• Draft section has been developed that includes different
fusion component types with an attempt to make it
country technology neutral.
24
Division 4 Initiatives (2 of 4)
Enhance global membership by establishing global
network of fusion users in Div 4 work groups.
• Establish 6 new work groups with officers and
membership representing global fusion user base.
– There are 15 members of the SG Fusion Energy Devices that
represent 6 different countries and many different global
companies.
• Establishment and approval of 6 work groups to be part
of the 2015 Edition
25
Division 4 Initiatives (3 of 4)
Global Involvement of Fusion Users in Committee
activities.
• One meeting a year of the SG Fusion Energy Devices
will be held outside of ASME Code Week and outside
of the USA.
– Two meetings were held in 2014 outside of the USA in China
and Oxford UK and two meetings were held in 2013 at other
global locations.
26
Division 4 Initiatives (4 of 4)
Develop rules for components that are considered
part of the pressure boundary and/or structural
integrity of a fusion system.
• This is being worked in a Phased Approach using the
approved Division 4 Roadmap.
• Target: Issuance of first draft of fusion component rules
by the 2015 BPV Edition
27
Division 5 Initiatives
High Temperature Reactors
28
Division 5 Initiatives
SG-HTR is currently updating their initiative and
development activities.
• Will review the planning for the 2017 code
edition and beyond 2017 editions in August
2014 and provide by August 2014.
