Operating Experience OE17929 - Nuclear Instrumentation System (NIS) Calibrated Using Incorrect NIS Currents

Purpose:

  • Present industry experience during power ascension NI adjustments.
  • Reinforce use of verification/validation, and Stop Wheni Unsure human performance tools.
  • Reinforce need to follow SQUG procedures.

Discussion:

Engineering generated 47% power currents during power ascension testing of a new cycle using new BEACON software, but extracted incorrect data from the output and sent it to the plant for installation. After these currents were installed, once the unit stabilized at full power, delta flux indications were 7% lower than predicted. After the cause/error was uncovered, correct currents from a full power map were installed and delta flux agreed with predictions.

Human Performance What is a post-job brief?

  • According to NP 1.6.10, Pre- and Post-Job Briefs, it is a review of recently performed tasks to identify strengths or weaknesses that can be used to improve future performances of the tasks.

What are your responsibilities for conducting or attending post-job briefs?

NP 1.6.10, Pre- and Post-Job Briefs, lists the following responsibilities:

  • Managers and supervisors establish requirements, ensure the adequacy of, and attend or conduct post-job briefs.
  • Site personnel request post-job briefs when necessary and participate using a questioning attitude.
  • With the exception of IPTE, personnel other than supervisors can conduct post-job briefings.
