Shipbuilding1972-1975
- Special Problem Only 2 reactors (wanted 4)
- Concern for overall reliability and safety
- Crew selection viewed as key to success
- Result (hindsight) Optimal NSC
8Navy NSC Basics
- Goal Optimal reactor systems control
- Achieved using best proactive methods
- No-fault policy for most situations
9NIMITZ PRECOMMUNITNewport News Shipbuilding
- Crew Selection
- First Year Crew training
- Second Year Construction support/testing
- Third Year Critical testing and acceptance
10NIMITZ PRECOMMUNITNuclear Safety Culture
- Officer (Manager) roles
- Enlisted Personnel (Worker) roles
- NSC-Related Policies
- NSC-Related Practices
11NIMITZ PRECOMMUNITNuclear Safety Culture
- Officer (Manager) roles
- Take charge/responsibility
- Support enlisted personnel (workers)
- Conduct training
- No problem filtering (key point)
- Continuous self-training/retraining
12NIMITZ PRECOMMUNITNuclear Safety Culture
- Enlisted Personnel (Worker) roles
- Achieve technical expertise
- Identify/report all technical problems
- Push for problem resolution
- Understand/control operations
- Procedure verbatim compliance
- Continuous self-training/retraining
13NIMITZ PRECOMMUNITNuclear Safety Culture
- NSC-Related Policies
- No-Fault Problem Management
- No Problem Filtering
14NIMITZ PRECOMMUNITNuclear Safety Culture
- NSC-Related Policies (2)
- Upside-Down Organization
- Managers support workers
- Workers are the most important personnel
15NIMITZ PRECOMMUNITNuclear Safety Culture
- NSC-Related Practices
- Daily self training
- Weekly formal training
- Monthly progress reports to CO from each
manager and worker - Stop testing and fix it
16NIMITZ PRECOMMUNITNuclear Safety Culture
- NSC-Related Practices
- Monthly progress reports from each manager and
worker - All reports go to CO (CEO)
- Each manager adds a summary report
- Each report includes work completed, problems,
obstacles, support needed, plans for next month - No filtering/no fault
17NIMITZ PRECOMMUNITNuclear Safety Culture
- NSC-Related Practices
- Stop testing and fix it
- Procedures (Verbatim Compliance)
- No interpretations
- Focus on red flags
- Stop, correct (all), approve, proceed
18NIMITZ PRECOMMUNITNuclear Safety Culture
- NSC-Related Practices
- Stop testing and fix it
- Equipment
- Up-to-date technical manuals
- System Expert Factory visits
- Access for maintenance
- Proper tools for maintenance
19NIMITZ PRECOMMUNITNuclear Safety Culture
- RESULTS
- Ship commissioned on time
- All equipment fully functional
- No sea-trial problems with reactor or
propulsion plants - NIMITZ Class aircraft carriers a key national
asset
20Three Key Points
- Strong leadership
- Workers first
- Communicate all issues
Good Nuclear Safety Culture requires strong
leadership to establish policies and practices
that put the workers first and that communicate
all issues to the top manager. -Charles R. Jones

22Good Nuclear Safety CultureMy Definition
Enabling framework
Positive inquisitiveness
The integrated body of specific characteristics
and personnel attitudes of an established nuclear
organizational environment consisting, in part,
of design, operations, maintenance, inspection,
and management policies and activities which
together ensure that problems are aggressively
sought out and that all concerns or issues raised
are promptly addressed in a way that maximizes
worker safety and public safety over the life of
the nuclear plant.
Safety over production
23Practical Implementation
- It is one thing to fix the general organizational
and communication infrastructures. It is another
to identify, implement, and sustain the needed
upgrades to the supporting infrastructure. - We also need to look at more nuclear-specific
concepts and articulate managements policies and
goals in those areas.
24Practical Implementation (2)
- From DB lessons-learned task force
- Acceptance of long standing hardware problems
- Weaknesses with the Employee Concerns Program
- Weak self-assessments
- Multiple examples of procedural noncompliance
- Lack of management involvement in safety
significant work activities - Lack of engineering rigor in their approach to
problem resolution - Strained engineering resources
25Practical Implementation (3)
- From DB lessons-learned task force - Other
contributors - Inspection guidance
- ASME code requirements
- Reactor coolant system leakage monitoring methods
and requirements - Inspection staffing issues
- Licensing processes
- Quality of documentation
26Practical Implementation (4)
- From DB Safety Culture Report
- Davis-Besse Key Safety Culture Issues
- Safety integration needed Industrial, Nuclear,
Traffic - Inadequate alignment of managers and non-managers
- Problem ownership weak
27Practical Implementation (5)
- From DB Safety Culture Report (continued)
- Realistic schedules are needed
- Minimal corrective actions due to production
pressure - Top down approach is overbearing
- Personnel low priority
- Organization chart not updated
- Training not a priority
28Practical Implementation (6)
- From DB Safety Culture Report
- Work coordination weak
- Reactive work vice planning to avoid issues
- Resource loading inadequate to solve problems
- Self assessments are sporadic and ineffective
- Professional development not provided
29NSC Fundamentals
- When do we apply verbatim compliance at this
nuclear plant? (When do we not?) - What do we mean by "configuration management" at
this nuclear plant and how do we implement it?
(Do we have control?)
30NSC Fundamentals (2)
- What do we mean by "life cycle maintenance" at
this plant and how do we implement it? (Are we
thinking long-term?) - What is our nuclear safety margin at this
plant? (What are we protecting? Does it
change?) - What plant barriers provide protection to
reliably prevent fission products from reaching
the environment? (Do we include protecting the
spent fuel?)
31NSC Fundamentals (3)
- What plant design features improve reliability
and compensate for equipment failures? (Are they
repaired/maintained at a higher priority?) - What makes instrumentation at this plant
accurate? (Calibration and actual system
testing?) - Can the fail-safe performance of equipment at
this plant be improved? (Is it checked and
protected?)
32Other Basic Concepts
- What will be management's disciplinary response
to an incident in which a worker made a mistake
that caused this plant to shutdown? (Management
responsible too?) - When we at this plant encounter a procedural
requirement that cannot be met as written, what
course of action will we take? (Reevaluate the
entire procedure rather than just the one item?
Skill-of-the-craft issues?)
33Other Basic Concepts (2)
- Risk informed methods provide a useful
prioritization tool but are not standalone,
definitive solutions. - Risk informed is too often skewed to imply that
something does not have to be controlled or fixed
at all. - Technical understanding and control are most
useful in proactive environments.
34Concluding Perspective
- A good Nuclear Safety Culture
- Important to the success of the nuclear
industry. - Requires communications up and down the entire
organization.
