Safety Culture

• Organizational Culture
• the shared basic assumptions that are developed
  in an organization as it learns and copes with
  problems.
• the basic assumptions that have worked well
  enough to be considered valid are taught to new
  members of the organization as the correct way to
  perceive, think, act, and feel.
• Safety Culture
• An organizations values and behaviors modeled
  by its leaders and internalized by its members
  that serve to make nuclear safety the overriding
  priority.
• INPOs Principles for a Strong Nuclear Safety
  Culture

IST Culture IssuesA Team Effort?

• Who owns the IST Issues?
• IST Engineer?
• Component Engineer?
• System Engineer?
• Maintenance Engineering or even from a Broke/Fix
  standpoint, Maintenance?
• Each site will have their own unique issues, or
  culture.
• Work in progress, constantly evolving as we
  address issues
• Detailed Program Documents will help improve your
  IST Culture
• IST Program Bases Document (LAN) to show what
  is/what is not/and why.
• IST Database (LAN) with adequate depth of
  content.
• IST Implementing Procedures Generic, Pump,
  Valves.
• Visible Interface with other key groups on site.

IST Culture Some Seabrook issues where we are
working to get ahead of the issue

• Instruments used for IST out of tolerance
  Adverse trend? What is the interval? First time
  event?
• Stroke Time What is the trend? How to know
  when it is adverse what rules are applied?
• IST Pump - Close to ALERT value, or fails
  surveillance test What was the trend? What/who
  is tracking the issue?
• Relief Valve fails setpoint test Repeat?
  Contingency? Expanded Scope? What other valves
  are impacted? What S/N is involved?
• Relief Valve not tested within required timeframe
  How and who is tracking? Change in model?
• Check Valves How to describe Check Valve
  Condition Monitoring activities Forward,
  reverse, interval, PMT issues?

IST Culture IssuesInstrumentation

• Pumps
• Recent IC Design calculations for Accuracy
• IC Maintenance Procedures or PM Tasks scheduled
  in Work Management process
• Protected steps for key attributes MTE,
  intervals, when to adjust, etc.
• Known locations for this info.
• Reviewed by IST Group for acceptability.
• Adequate Technical Rigor used in these reviews?
  Partnering with Pump and System Engineer for
  margin issues? (KPIs)
• Database feature select by instrument,
  historical sheet showing AF/AL results, past ARs
  and corrective actions.
• OX1456.86 contains all relevant acceptance
  criteria info used as the technical bases for
  Operations.

IST Culture IssuesStroke Time Variations

• What has the historical trend been? Slow and
  gradual?, versus sudden step? Margin issue?
• How determined? At- a-glance, or graphical, or
  statistical analysis?
• When does troubleshooting begin? Some valves,
  like AOVs, require partnering with Program
  Engineer (KPIs)
• Immediate retest performed?
• Control Room or local?
• Database feature graphical presentation
• OX1456.81 contains all relevant acceptance
  criteria information used as our technical
  bases for Operations.

IST Culture IssuesPump Issues

• Hydraulic Condition
• what is the bases?
• Degradation taken in long term view (e.g. stair
  step versus basement view), Head curve as
  original test bases? (KPIs)
• Scatter issues used to improve test methodology?
• Mechanical Condition
• Smooth running pumps and use of analysis being
  identified as margin issue?
• Design issues identified with corrective actions?
  
• Operations interface ON LINE versus Outage
• Baseline procedure protocols
• Shop head Curve test with vibrations as practical
• In situ Head Curve performed with IST (patience)
• CBM taking vibrations and performing analysis

IST Culture IssuesRelief Valve Issues

• RV Issues
• Some Design changes to replace obsolete valve
  designs
• Change in trending
• Standardization of tail pipe to permit
  interchangeability
• Outage Planning for failures train rolls,
  additional testing.
• Not much expanded acceptance criteria (PZRs,
  MSSVs for AF testing)
• Hot/Hot Testing
• ES1850.011 Procedure, EX1804.044 for IST Valves
• Tracking of AL post refueling Outage??
• In house AR
• PZRs shipped

IST Culture IssuesCheck Valve Condition
Monitoring Issues

• Two separate databases
• One on LAN and one in Group Drive
• Needed increased visibility
• Database Demonstration
• Analysis bases
• Forward Activity by activity/interval
• Reverse Activity by activity/interval
• Technical Rigor
• Two person review next outage focus.
• Instrumentation issues
• instrument accuracy

Monitoring Issues

• Post Maintenance Testing issues
• Planner Interface
• Component Engineer interface
• Outage Planning correct sequencing
• Performance Monitoring
• PWR PIV testing performance based
• Trending for next outage issues
• Transfer to OPS for SI Test Header Operation
• Not just getting to SAT
• Sequencing of the testing test second outs
  before first outs get seated by RCS Pressure.

39
IST Culture IssuesTrending vs. Data Entry

• Data Entry does not equal trending
• Technical Specification compliance verification
  of the activity and that it meet acceptance
  criteria
• Performance Monitoring review - multi layered
• Identify adverse trend
• Focus on next outage activities
• Adjust knowledge of component performance
• Interface with System, Component, or other
  Program Engineers
