SUBJECT:

TMI-2 CONTAI.PEMT INFORMATICM In' response to'your memorandun of June 14, 1979,, the Containment Systems Branch proposes that the plans for-containment entry and subsequent cleanup operations include. the following:

s

1) Observations on character and distiibutica of debris around the containment ssp.aree, and near or artund isolation valves that are open to the contairant; atmosphere;..

.~..;,.;

2) Observations on insulatton mterials, both metallic and non-metallic, to determine the amount if any that came off of piping systems, and whether there'was. anar deterioration of s

non-metallfe insulation;.

3) Observations orr. paints, to detennine the amunt if any that has.

peeled off of walls, whether there is any blistering of thr-existing paints; and whether they contriboted as source terms for hydrogen; w.

4) Observations on tre containment' Tiner to determine whether there are any bulges or other physical distorttons;

5) Observaticns related to the amount of water on the floor; e.g., the elevation of the water level; and

6) Exar.rination of any evidence that might be used for characterizing the spray coverage when the contairrient spray system actuated.

In all these " observations", liberal use should be made of T'l recording, voice -

recording, still phctography, etc. to provide the best possible record of the situation.
