Safely Extend Equipment Life with Fitness for Service Evaluations

As the nuclear fleet across North America ages, plant owners face growing concerns about degradation and damage to safety-related systems. IIA is a leader in the use of non-destructive examination (NDE) to locate flaws, fractures, fatigue, corrosion and cracking. But what happens next?

Nuclear plant owners must weigh a number of factors in deciding whether to make immediate or deferred repairs, replace the part or equipment, or continue operating at full or reduced capacity — all while protecting personnel and the public and addressing economic and regulatory considerations.

Fitness-for-service evaluations can help make these complex decisions crystal clear — and IIA can help. Our licensed professional engineers are experts in fracture mechanics and fatigue and skilled in performing finite element analysis and other modeling methods.

What is a Fitness-for-Service (FFS) Evaluation?

Most often, FFS is used to help plant owners make well-informed run-repair-replace decisions after a flaw or damage mechanism has been identified. FFS can also be undertaken proactively to maximize equipment life and enhance inspection and maintenance planning.

FFS Benefits

When performed by qualified engineering experts like those at IIA, an FSS evaluation can be used to help plant owners:

  • Safely continue operation after damage or defects have been identified
  • Make well-informed, data-driven decisions to run, repair or replace
  • Respond faster and more effectively to flaws and failures
  • Enhance and customize outage and inspection planning and timing
  • Quantify the remaining life of your asset
  • Develop targeted repair procedures
  • Integrate into an asset management program to reduce risk and costs and maximize efficiency
