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


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


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


• 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


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


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


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


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


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


Concrete

Containments

16


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


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


Containments for Transportation

and Storage of Spent Nuclear

Fuel and High Level Radioactive

Material and Waste

19


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


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


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


Fusion Energy Devices

(in development)

23


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


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


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


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


High Temperature Reactors

28


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.
