REACTIVITY CALIBRATIONS AND FISSION-RATE DISTRIBUTIONS IN AN UNMODERATED, UNREFLECTED URANIUM-MOLYBDENUM ALLOY RESEARCH PROGRAM (open access)

REACTIVITY CALIBRATIONS AND FISSION-RATE DISTRIBUTIONS IN AN UNMODERATED, UNREFLECTED URANIUM-MOLYBDENUM ALLOY RESEARCH PROGRAM

Completion of zero-power critical experiments with the ORNL Health Physics Research Reactor is reported. A description is given concerning these experiments which were used to determine the critical size, fission-rate distributions, reactivity calibrations of its movable parts, the temperature coefficient of reactivity, and the reactivity effects of the presence of neutron- reflecting materials adjacent to the reactor.

[Letter from Bill McCarter to Howard Dunn and Janice Wiggins, March 10, 1990] (open access)

[Letter from Bill McCarter to Howard Dunn and Janice Wiggins, March 10, 1990]

Photocopy of a letter from Bill McCarter, co-director of North Texas Institute for Educators on the Visual Arts, to Howard Dunn and Janice Wiggins, Dallas ISD. Inviting Dallas Independent School District into a five year plan with NTIEVA, since their last minute implementation process prevented Dallas from becoming part of the Institute previously. Details about what is required from the district is written at the end of the letter and that McCarter will be happy to discuss further details of financial obligations.

[Letter from Chad Woolery to Bill McCarter, Jack Davis and Nancy Reynolds, May 10, 1994] (open access)

[Letter from Chad Woolery to Bill McCarter, Jack Davis and Nancy Reynolds, May 10, 1994]

Photocopy of a letter from Chad Woolery, General Superintendent of Dallas ISD, to Bill McCarter, Jack Davis and Nancy Reynolds, North Texas Institute for Educators on the Visual Arts. Thanking McCarter and co., for his invitation to a special Administrators Day at the Dallas Museum of Art, however, Woolery is concerned that there are only five of the Dallas I.S.D. areas being represented in the group of invitee and that within his letter he asks the area directors to ensure that all ten areas are included on that day by replacement or addition. Woolery ends the letter by stating that due to his schedule, it will not permit for his full attendance but he'll share lunch and some of the afternoon's agenda what he can. Copied on the letter is Bill Cormack.

[Letter from Bill McCarter and Nancy Cason to Janice Wiggins, May 10, 1991]

Photocopy of a letter from Bill McCarter and Nancy Cason, North Texas Institute for Educators on the Visual Arts, to Janice Wiggins, Art Supervisor of Dallas ISD. Thanking Wiggins for her time working with NTIEVA, and meeting with Dr. Brooks-Ray and Howard Dunn to discuss interest in the program for staff development. The Institute and the district face uncertain economic conditions but McCarter and Cason believe if they could stretch their first year budget they could pay a team member (kindergarten and first grade teacher, art specialist and principal) a stipend of $50 a day to attend the three-week institute during the summer. However, since Dallas was not written into the original implementation grant they will have to review it with the Getty Center and cannot promise continued support past the year.

Super-Prompt-Critical Behavior of an Unmoderated Unreflected Uranium- Molybdenum Alloy Assembly (open access)

Super-Prompt-Critical Behavior of an Unmoderated Unreflected Uranium- Molybdenum Alloy Assembly

The time-dependent behavior was investigated of the neutron population in an unreflected unmoderated cylindrical assembly of 90 wt.% U (93.2 wt.% U/sup 235/), 10 wt.% Mo alloy following rapid establishment of a super-prompt critical c ondition with negligible initial neutron population. Reactivity increases up to 11 cents above prompt critical resulted in bursts yielding as many as 1.8 x 10/ sup 17/ fissions with reactor periods as short as 16 mu sec and temperature increases as large as 400 deg C. Pressure waves generated in a portion of the core held in position by an electromagnet for bursts greater than ~6 x 10/sup 16/ fissions initiated the removal of this section about 225 mu sec after the peak burst.

Synthesis and characterization of a new silicone multiblock polymer (open access)

Synthesis and characterization of a new silicone multiblock polymer

The Lawrence Livermore National Laboratory (LLNL) has an active interest in the synthesis of new polysiloxanes as base polymers for cellular silicone materials. These elastomers have properties uniquely suited to very specific engineering requirements. While the polymers which we have prepared via random equilibrium of various cyclic tetrasiloxanes have adequate properties for certain applications, there is evidence to suggest that alternating block polysiloxanes prepared via condensation-polymerization techniques have properties more suited to our end uses as flexible foam materials (cushions). The synthetic sequence developed to prepare these materials involves reactions of functionally terminated (silylamino and silanol) polysiloxane oligomers to produce alternating multiblock (ABAB...) materials of high molecular weight. Dialkylamines are condensation byproducts in this reaction. The analysis and characterization of these multiblock polymers is reported.
