License Amendment Request

  • Approval of USAR changes that revise the PINGP Quality Group classification for certain fuel handling equipment from QA Type I (safety-related) to QA Type III (commercial grade)
  • Changes are consistent with industry standards

- ANSI/ANS 58.14-1993 Section 5.6.1, Item 9

  • Purchasing safety-related spare parts does not provide commensurate public health and safety benefits.

=

Background===

  • PINGP was designed and build in late 1960s/early 1970s

- Prior to issuance of GDCs

- Before guidance for classifying SSCs

  • Original A/E developed standard of 1% of 10 CFR 100 limits for classifying SSCs

=

Background===

- 10 CFR 50.67 replaces 10 CFR 100 as licensing basis

  • Fuel handling accident offsite dose consequences fall below 10% of 10 CFR 50.67 limits.
  • Fuel handling equipment is currently classified as QA-Type I (safety-related)

Scope Fuel Handling Equipment to be Reclassified as QA Type III:

  • Auxiliary Building Crane
  • Spent Fuel Pool Crane
  • Manipulator Cranes, including Load Cells
  • Spent Fuel Assembly Handling Tools
  • Rod Cluster Control Changing Tools
  • Spent Fuel Transfer System and its constituent components (conveyors, upenders, and related equipment), exclusive of transfer tubes and blind flanges

Example Additional Information

  • The QA classification of fuel handling equipment, including cranes, is not discussed in the NSPM QA Manual
  • The scope of this amendment does not impact important to safety SSCs described in the PINGP ISFI USAR.
  • Approval requested by September 1, 2019 to support 1R30
  • Precedence

Summary

  • Original PINGP classification scheme (1% of 10 CFR 100 limits) is more conservative than current standards
  • Fuel handling accident consequences fall below 10% of 10 CFR 50.67 limits
