.a Dadground Dy letter dcted Novcber 21, 1977, FPC propered c cnwi:e to the CH-3 Technical Specifications ragmiing containrent tendon surveillance.
This chance would scacif'v minirm liftoff force per wire instead of per tendon,-while sti11 allowing tenden ferce to E tracked with time, and ITo~uTfplace a time dependent limit en wire iirtoff force to account for expected loss of pre stress.
During discussion with FPC
~and Gilbert Associates Inc., we requested verification that satisfactory surveillance results throughout the life of. the facility would assure
- that containment design criteria were' met.
In response FPC requested this meeting to present.a,furtherredified tendan surveillance program.

FPC pro' pose' a subeillan[e progrim in which all tendons of a given d
type -(Hoop. Vertical and Dc:c) would be classified by groups of similite tendon prestress. This would; allow different liftoff forco li: nits for
, tendons with different nurbers of originally effective wires while continuing to pecify liaitts in terms of liftoff force per wire.
cPC:would use the nuecer of, effective wires in a tenden as determined w.
at initial. tensioning-to ' convert from observed tendon liftoff force to liftoff force per wire thuscaccurately indicating tendon degradation :. -"
throughout life.
.In addition, FPC proposed to classify sicme tendons cix as not eligible.for random selectionJof testing based on these -
