Time behavior of a critical reactor pulsed with a large square wave source

Description: In a previous Naval Application memorandum, a discussion was given of what happens to the power level of a reactor when an instantaneous, very large neutron source is introduced. The motivation for the problem arises from the question of what happens when a nuclear bomb is detonated near a reactor powered missile. This present memorandum looks at the same problem as that which is discussed in the previous memorandum but in slightly more detail. The results obtained are essentially the same as those of the previous memorandum with somewhat more attention given to the nature of the assumptions made. The kinetics model used is the space-time separable, one delayed group model. Space-time separability is almost certainly a poor assumption in this case. When a very large neutron wavefront impinges on a reactor, the subsequent short time behavior can hardly be that predicted by this simple model. One would expect very large local power densities in one part of the core before another part would see anything unusual. The other assumption, one delayed group, is not necessary but makes the mathematics simpler and in view of the first assumption is probably quite acceptable. In spite of these simplifications the model gives results which should have,qualitative physical relevance.

Numerical results of PT-IP-338A and supplement A: DR reactor heat decay test at high outlet water temperatures

Description: This report summarizes the results obtained in the experimental measurement of the reactor heat extracted by the coolant during two different scrams of the DR Reactor. These tests were conducted with the reactor flow carefully controlled to establish different reactor coolant temperatures following the scram. During normal reactor scrams, which have been used in the past to measure the reactor heat output, a high coolant flow was maintained. Consequently, the coolant outlet temperature dropped very quickly from an operating value of 90 to 95 C down to 20 to 30 C following the scram. Under emergency conditions, however, with only the last ditch emergency flow available, the coolant outlet temperature could remain as high as 80 to 90 C. This condition could prevail because of the small amount of last ditch flow available, and could last for 5 to as long as 70 minutes after the reactor scram.

Design scope of the Z Plant Metal Control Facility, Project CGC-944

Description: The steadily increasing plutonium production rates in the 234-5 Building has resulted in a large increase in the number of PR cans that are now being handled in the building. This has resulted in the available receiving and storage places for PR cans being taxed beyond their full capacity thereby necessitating the storage of PR cans within the building corridors. Accordingly, the ten-year business plan for the 234-5 Building, as documented in HW-65000, included a program for providing new receiving and storage facilities to alleviate this problem. The purpose of this document is to present a complete process engineering design on the combined receiving, storing, and blending facility. This document will provide the basis for the preparation of all subsequent Title 1 and Title 2 designs of this combined facility which has been given the title of Metal Control Facility.

Reactor thrust during boost in a high altitude trajectory

Description: Reactor startup of a submarine based missile must be accomplished during boost., so that at burnout the reactor maximum wall temperature is at or near the design value. Because cooling air must be supplied during this period, there exists the possibility of obtaining some thrust to augment the booster. To find how much reactor thrust might be available, a representative high altitude boost trajectory was selected. This is shown together with an estimated pressure recovery curve for the inlet. It has been assumed that by some appropriate means the flow rate passed by the inlet exactly matches that demanded by the reactor and nozzle. Hot day conditions are assumed. The missile power plant was the Tory II-C reactor with its design point-optimized nozzle throat area of 750 square inches. Nozzle expansion is complete. The reactor maximum wall temperature was assumed to be constant at design (2500 degrees F) from time zero. Thus the thrust computed at any time is the maximum possible within the reactor design temperature limitation, and provides a guide to a desirable startup time. Available thrust and reactor exit conditions were obtained with the digital codes Dash N and Nomac.

Reactor process flow technical data

Description: A computer program is being developed for the solution of general system flow problems. As a complement to this program, a summary of the process system has been prepared. This assembles information from a number of different reports, drawings and technical notebooks into one place for easy use and reference. It is expected that the information contained in this report will be of use in safety and design studies of these process systems. This report presents current values of the reactor flow characteristics and the primary pumping system characteristics. It also presents the process piping system and the basis for a computing program for calculating system pressure drops.
