450/sup 0/F step transient thermal analysis of the LOFT pressurizer surge and spray line piping

Description: The LOFT pressurizer spray and surge line piping was analyzed for a 450/sup 0/F step change in fluid temperature. This transient was chosen to conservatively represent several pressurizer operating transients that had not previously been analyzed. These include temperature transients resulting from a 300/sup 0/F ..delta..T between pressurizer temperature and cold leg temperature, injection of a cooled (70/sup 0/F) slug of stagnant fluid into the hot (540/sup 0/F) spray line piping, and inflow o… more

Slicing of silicon into sheet material. Silicon sheet growth development for the large area silicon sheet task of the Low Cost Silicon Solar Array Project. Fifth quarterly report, March 21, 1977--May 27, 1977

Description: The multiblade slurry technique capable of slicing 10 cm ingot into wafers 0.25 mm thick with only 0.20 mm kerf loss and 98% yield has been demonstrated. The total silicon requirement represents an ingot to sheet conversion of 0.95 m/sup 2//kg. Full production slicing tests have demonstrated the cost of MS slicing to contribute $40 to $50/m/sup 2/, with ''best effort'' estimates for today's configuration to be $30 to $35/m/sup 2/. By reducing material cost, and increasing the specific capacity … more

LASNEX: pondermotive force algorithm

Description: The new algorithm used to calculate the ponderomotive force in LASNEX is discussed. The algorithm is shown to be identical with the corresponding analytic expression when the WKB solution for the fields in a plane-parallel medium is used. LASNEX calculations performed to check the ponderomotive force algorithm are described. 2 figures.

Measurement of the neutron-induced fission cross-section of /sup 243/Am relative to /sup 235/U from 0. 1 MeV to 30 MeV

Description: Continuing studies of fission cross-section ratios at Lawrence Livermore Laboratory have led to the measurement of the /sup 243/Am//sup 235/U fission cross-section ratio from 0.1 to 30 MeV. A value of 1.429 +- 0.037 was obtained for the average cross-section ratio from 1.75 to 4.00 MeV by use of the threshold method. 2 figures, 1 table.
