The interaction of possible nonoxide containment materials (including boron nitride, titanium nitride, hafnium carbide, and two cerium sulfides) with uranium or carbon has been examined by thermal analysis techniques. Additionally, nonoxide-ceramic interaction with beryllia, tungsten, or yttria was investigated. Hafnium carbide is the least reactive nonoxide ceramic tested.

This status report includes brief reports on measurements and calculations of quantities for nuclear data applications and data for reactor safety. Separate abstracts were prepared for those items with a significant amount of data. (RWR)

Twenty papers were included covering the Edna Delcambre Test Well, legal studies, environmental studies, economic studies, and resource utilization. Separate abstracts were prepared for each paper. (MHR)

An analysis is presented of combined stresses in the LOFT Modular DTT for specified temperature gradients. All combined stress intensities are shown to stay within applicable allowable stress intensities. A fatigue analysis is also presented which indicates that the LOFT Modular DTT will withstand 70,000 blowdown cycles. The LOFT Modular DTT is shown to meet the Class 1 stress requirments. A stress analysis of the tab region of the newly designed MDTT tab-type shroud is included. This stress analysis shows that the Class 1 stress requirements are met by the tab-type MDTT shroud design and that this design imposes no fatigue life limitation on the MDTT.

Measurements were made of the neutron spectrum produced by bombarding a thick beryllium target with 30-MeV deuterons at the University of California, Davis cyclotron. This spectrum is of interest in studying the effect of neutrons on materials to be used in future fusion reactors. The spectrum was inferred from the activation of two sets of detector foils placed at 0/sup 0/ to the deuteron beam, one immediately behind the beryllium target block, and one 40 mm to the rear. A least-squares program was used to analyze the foil activation data to obtain the fluence in each of seven energy groups. The neutron spectrum (fluence/MeV) close to the target decreases continuously with energy in the range 5-32 MeV, while the spectrum 40 mm back has a peak at about 13 MeV. The contribution from neutrons of energies less than 10 MeV is much greater than that found in previous spectral measurements made at large distances from the target. This difference is attributed to the neutrons which are emitted at large angles from the deuteron beam. These observations show the importance of evaluating the neutron spectrum near the target if samples of materials are to be irradiated in this location. (auth)

Lines 1''-BSV-10-VD and 1/sup 1///sub 2/''-BSV-10-VD were analyzed to ASME Section III, Subsection NC (Class 2) criteria. The lines are part of the Waste Gas Processing System. The model considered the portion of the lines outside the containment. The analysis showed that Class 2 requirements will be met with the pipe supports specified in this report.
