CONFIDENCE
Compliant with 10CFR50, Appendix B; 10CFR21; ANSI/ASME NQA-1, and is audited by NUPIC.
Structural Integrity Pipe Evaluation (SIPE) web-enabled software performs Code Case N-513 evaluations to quickly evaluate thinned or leaking pipes to meet ASME and NRC requirements.
What is SIPE?
SIPE software performs Code Case N-513 evaluations from any web enabled device so you can quickly evaluate thinned or leaking pipe to determine if it meets the ASME and NRC requirements for structural stability. If so, repair or replacement may be deferred until the next scheduled refueling outage provided other N-513 requirements are met related to subsequent examination and extent of condition.
Code Case N-513 is one of the most widely used Code Cases in the Nuclear Industry. SIPE implements the structural evaluation of Code Case N-513 and can be used to support temporary continued operation without repair or replacement.
Flaw Evaluation Decision Tree
When it comes inspections or leaking flaws, you have options. Analysis and repair options are available for both temporary acceptance and extended acceptance. Contact SI to find out more.
CC N-513 SCOPE
Temporary Acceptance
Temporary Acceptance for Continued Operation
♦ Leaking
♦ Thinned
Temporary Acceptance
♦ Until next scheduled refueling outage
♦ 513 cannot be used to justify startup
Moderate Energy
♦ Temperature 200°F or less or less
♦ Pressure 275 psig or less
Applicable to:
♦ Straight Pipe
♦ Elbows
♦ Tees
♦ Reducers
Approaches
Four different approaches for evaluation♦
♦ Part-wall nonplanar
♦ Part-wall planar
♦ Through-wall planar
♦ Through-wall nonplanar
N-513 is most appropriately applied to leaking flaws using
♦ Through-wall
♦ Planar Characterization
