The repair work will be evaluated to assure that the maintenance activities did not have any. adverse effects concerning the operating characteristics of the reactor.

2.

An investigation will be conducted to assure that leakage from the holes in the liner did not result in unauthorized radioactive liquid releases.

3.

If your understanding of the above is different, please notify me immediately.
