Part 1: Technical Position on Piping System Installation Tolerances
Summary
The Technical Position provides tolerances on the as-built geometry of Light Water Reactor piping and pipe support locations that are considered acceptable for reconciliation with as-designed geometry.That is, a piping system geometry that is in compliance with the plant licensing commitments based on the as-designed documentation is also considered to be in compliance if the reported as-built critical to design dimensions do not exceed the total tolerances presented in the Technical Position.
