MEMBERS
•
•
ASME, ANS, IEEE, Owners Groups, EPRI, NEI, DOE, and NRC
Committee can also include interested standards developing organizations,
such as ASTM, NFPA, and AISC
PURPOSE AND OBJECTIVES
•
•
Coordinate codes and standards activities related to risk management for
current and new nuclear power plants, nuclear facilities, and the
transportation and storage of nuclear material
Ensure that codes and standards associated with risk management, and
their underlying principles, are consistent and compatible
CURRENT ACTIONS
•
•
Facilitates coordinating activities between ASME, ANS, and IEEE on riskinformed initiatives
Acts on inputs from industry and regulating organizations relative to the use
of risk methods in codes and standards
10
JCNRM Overview
11
JCNRM CHARTER
• To
develop,
revise
and
maintain
standards and guides on probabilistic
risk assessment (PRA) and related risk
management techniques supporting risk-
informed
and
performance-based
applications for nuclear facilities.
12
JCNRM SCOPE
• The development of standards and guidance that
establish risk criteria and methods for PRA, risk
assessment, and risk management for nuclear
facilities.
• Review of standards as requested by other
American Nuclear Society (ANS) and American
Society
standards
of
Mechanical
committees,
Engineers
and
other
(ASME)
standards
development organizations on related topics to
identify inconsistency, lack of integration of risk
concepts and duplication, as appropriate.
13
JCNRM Overview
• National consensus committee
• ~70 volunteers working in all JCNRM
organizational areas
• All nuclear sectors interest areas
represented
• Member rosters can be found on
JCNRM web page

WGs beginning in 2016
20
Subcommittee on Risk
Applications
• Chair Ken Kiper/Vice Chair Stanley Levinson
• Project Teams - New PT on interface with BNCS
Board Committee Nuclear Quality Assurance
(NQA) to facilitate and improve 50.69
implementation
• Primary Focus 2014-2016 - Establish POCs with
key stakeholder organizations & national
consensus committees with risk initiatives
21
Strategic Plans
22
ASME BNCS Risk Management
Strategic Plan
MISSION
Factor risk, as well as performance, into all ASME Nuclear Codes and
Standards, as appropriate, to further ensure, on a worldwide basis, that
they protect public health and safety and meet the needs of users
ACTION PLAN
Identify and track short-term (1-2 years) and long-term (3+ years) riskinformed initiatives within the Committee on Board Operations and
across all BNCS Committees
PRA STANDARDS DEVELOPMENT
Identify needs to enhance or develop PRA Standards to support
applications defined in the action plan
UPDATES
Plan is updated and approved at each BNCS meeting (~4 months) and
is then placed on the ASME website for public access
23
ANS Standards Board Risk
Management Strategic Plan
• The American Nuclear Society Standards Board (SB) has established
the Risk Informed and Performance Based Principles Policy
Committee (RP3C) as a committee that reports directly to the SB.
• The RP3C is responsible for the identification and oversight of the
development and implementation of the ANS Risk Informed and
Performance Based Standards Plan that establishes the approaches,
priorities, responsibilities and schedules for implementation of risk
informed and performance based principles in American Nuclear
Society (ANS) standards.
• The RP3C is also responsible for reviewing standards being developed
by other standards developing organizations as assigned by the ANS
SB on related topics to ensure consistency.

Risk-Informed Applications
Support
29
Regulatory Infrastructure
• RG 1.200 endorses PRA Standards
• Other supporting RGs for applications are
– RG 1.174, Risk Informed Licensing Changes
– RG 1.175, Risk Informed Inservice Inspection
– RG 1.177, Risk Informed Technical
Specifications
– RG 1.201, Risk Informed Categorization &
Treatment of SSCs
– RG 1.205, 50.48(c) Fire Protection, NFPA 805
– RG 1.206, 10CFR52, New Plants
30
Use of PRA Results in
Regulatory Applications
• NRC has adopted a risk-informed approach to use of
PRA in regulatory decision-making (Risk Informed
Regulation)
• The philosophy is discussed, in the context of
changes to licensing basis, in RG 1.174
• PRA analyses are one, but not the only, input to the
decision
• NUREG-2150 describes a proposed risk management
regulatory framework
31
Risk Informed Regulatory Areas
– Maintenance Rule (10CFR50.65),
– Mitigating Systems Performance Index
(MSPI),
– Reactor Oversight Program/Significance
Determination Process
32
Industry PRA Applications
Risk-Informed Applications used by US NPPs
• On-Line Maintenance, Configuration Risk
Management, Risk Informed Inservice Inspection
(prior to PRA Standard)
• 10CFR50.69, Risk Significance Categorization
• Risk-Informed Technical Specifications
– Risk-Managed Tech Specs (Flexible Allowed
Outage Times) (RITS 4B)
– Surveillance Frequency Control Program
(RITS 5B)
• NFPA-805 (Risk Informed Fire Protection)
• Risk-Informed GSI-191
33
PRA Standard Utility Interfaces
Utility PRAs use the guidance in the
Standard for establishing in part or in
whole:
• Role of Peer Reviews
• Risk-Informed Application Process
34

Opportunities to Participate
• Subcommittees
• Working Groups (permanent JCNRM
technical groups)
• Project Teams (temporary teams
chartered to address or resolve a
specific short term activity)
38
INSIGHTS
• Codes & Standards are the consensus mechanism
to develop guidance and requirements for industry
use and subsequent regulatory endorsement
• Many areas need attention and further development
• Opportunities to help ensure that technical
requirements ultimately to be imposed on Users are
accurate, efficient, and effective
• What is contained in C&S typically become
requirements (participation is important)
• Good opportunity for younger professionals to have
a voice in their future
