During a trip to Chicago, Wahl was introduced to the Argonne
personnel, along with M. H. Smith and C. N. Gross of the
Manufacturing Division. While they familiarized themselves with
the apparatus, our most recent drawings were reviewed with Zinn,
Anderson, Marshall and Woods, They had already been gone over
with Wigner's men the day before.
The increase in radioactivity in the water caused by the presence
of a failed coating was discussed with Wigner and Wollan. Data
from CC680 by Coryell will be used to calculate the effect
quantitatively.

Chicago - June 8 and 9
A meeting on the corrosion of aluminum by Columbia River water was
held at the Metallurgical Laboratory on Tuesday. All the Chicago
staff interested in this problem were present together with
R. B. Mears, Zay Jeffries, C. P. Kidder, and the writer.
A major part of the meeting was given over to a discussion of
Mears' and Howe's results on potential measurements of various
alloys in Hanford water. Briefly, the data obtained indicate
that 72S will protect 2S at 70*C. Zinc and plain carbon steel
would also be protective, while the stainless steels, copper and
graphite cause the attack to take place on the 23.
For laboratory corrosion tests by Mears and Howe, the following
water composition was agreed upon as representing an ideal,
obtainable analysis.
Starting with distilled water
pH - 6.5 (Mears-
Cl - 1 p.p.m.
02 - .04 p.P.m.
HCO3 - 5 p.p.m.
C02 - 3 p.p.m.
Na - 0-1 p.p.m.
Heavy metals - less than .1 p.p.m.
H202 - 10- mols per liter
Dr. Jeffries suggested that since Mears was now familiar with the
entire corrosion problem, the Aluminum Co. be given a couple of
weeks to think over the situation in the light of their past
experience and present to us a possible solution.
