The increase in process tube outlet water temperature to 90{degree}C resulted in increased emergency water flow requirements as indicated by recently approved curves which establish minimum crossheader pressure requirements for the first three minutes following an electrical power failure. To determine whether 190 Building secondary process water pump capacities are adequate for current minimum reactor water pressure requirements, process water pump trip-cut tests are being conducted at all reactors by the Process Unit in accordance with recommendations of the Reactor Process Committee. The results obtained to data in these tests, as well as current plans for the remaining tests, are presented in this document.

The hiring schedule was reviewed by the same method that was used in the reference letter with essentially the same results; that is, that we should hire approximately 125 technical graduates during the hiring year 1953-54. In the belief that possibly this method was a bit too crude for this stage of the Plant development, I have applied another one, which I believe is fairly independent of the previous method of calculation since it is directed at a consideration of only people required who have a technical background.
