(1) As best one can measure at the reactor there is adequate clearance for the water windows; as indicated by dimensions below Auditorium:17'-1 3/4" x 5'-3 3/4" }inside dimensions, concrete to concrete Control room:5'-4 5/8" x 4'-4" the windows are 5'-2 3/4" x 4' 2 3/4" outside dimensions It may be seen that there is a one or two inch clearance everywhere.

(2) Talked with Mr Yow, Peden steel who reports that water windows should be done shortly. With reference to painting I would suggest the following. Peden Co. that we specify that the insides of the tanks be sandblasted and painted by Peden Steel according to the recommendations of the Amercoat Corp. (attached) the first or prime coat is supposed to be put on immediately after the steel is sandblasted, which would make it difficult to guarantee if they were prepared by Peden and shipped to us. Mr. Yow said they could procure the paint and apply it as we wanted.

The alternative is to do it ourselves. I don't think we could do as well. Give me your opinion on this

RM Yes. CKB I leave it to you to go ahead. CKB P.S. My estimate of cost of paint is given below. total area to be painted, 5 windows 100 ft2 Less than 1 gallon each of the five coats are needed, but assuming that a full gallon is bought, the cost is Prime 780 Body 1 850 Body 2 " times Seal 1 " Seal 2 " 41.10 We could probably get the excess paint for other uses.
