The first formal Fitness-for-Service (FFS) assessment methodology in the CANDU®industry was issued to the AECB in 1991 in the CANDU Pressure Tube Fitness-forService Guidelines (FFSG), which were later incorporated into CSA N285.8 in the mid 1990s. 

While the utilities have continued to benefit greatly from repeated, successful FFS assessments, industry changes since 1991 have conspired to apply mounting pressures on the FFS community, to the potential detriment of the assessment process.   

This paper identifies inherent challenges, historical challenges, and more recent difficulties encountered by the FFS assessment community and gives recommendations for relieving some of the mounting pressures on the FFS assessors and for improving the FFS assessment process.
