Interferometric observation of flow about an isentropic (reverse Prandtl-Meyer streamline) compression wedge at Mach 3.0

Description: Report presenting an interferometric study of the flow over a two-dimensional isentropic compression surface at a Mach number of 3.0. The flow field was essentially that of a strong-branch-shock configuration resulting from a surface flow turning that corresponded to an empirical limiting value of free-stream normal-shock pressure rise.

Interim report No. 1, RT 105-577-A: Irradiation of solid and cored hot pressed fuel elements

Description: In order to evaluate the performance of uranium slugs canned by the hot press method, several tubes of this metal were charged at C Pile and scheduled for irradiation until a specified number of ruptures had occurred. At the present time, all scheduled ruptures of hot-pressed slugs have been obtained. This report summarizes the irradiation experience under this test and the results obtained to the present time, and presents conclusions which are drawn from this experience.

Interim report, Poison splines flexible control system

Description: This report discusses a system which has been conceived whereby additional flexible reactivity control in the production reactors can be achieved by introducing neutron absorbers contained in thin flexible metal strips between the slugs and the process tube wall. These splines are potentially attractive in that it is possible they could be used to provide additional flexible control during operation as well as temporary control during outages.

Interim report, Production Test 105-522-E, Examination of pile process tubes removed from 100-C, D and F piles

Description: This report covers the examination of thirteen process tubes seven from F Pile, three from C Pile and three from D Pile. Five of the thirteen tubes were removed because they were leakers, four from F Pile and one from C Pile. One tube from F Pile and one from D Pile were removed. Reactor Section had requested the removal of two from F Pile to check for external corrosion. Two tubes, small diameter old pile annulus, were removed from C Pile under PT 105-519-E, ``Raising Permissible Outlet Water … more

Interim report - Production Test MR-105-12 crossheader purge with chromic acid

Description: The primary purpose of this test was to demonstrate that the inside of a rear-cross-header, its nozzles and pigtails could be decontaminated by recirculating for 30 minutes, a 60{degrees} C, O.3 pH chromic acid solution. Secondary purposes were, (1) to determine the magnitude of radiation increase in piping and acid equipment external to the reactor encountered during the test and (2) to obtain information as to the kind and amount of contaminants removed by the acid solution.
