摘要:

AbstractThe effective cross section for the16O(d, n)17F reaction for fission neutrons moderated by D2O has been calculated, using the recoiling deuteron formalism of Hammar and Forsén. A value of∑n= 4.8×10-7cm-1is reported.

摘要:

AbstractValues of the yield of delayed neutrons from fission previously reported by Masters, Thorpe, and Smith and by Krick and Evans have been reevaluated following refinement of earlier measurements and calibrations. Except for238U, the values for fast fission are in agreement with earlier results of Keepin.

摘要:

AbstractA simple merit index has been derived to compare potential improvements in gas-cooled nuclear reactor cores, such as artificial surface roughening of the fuel rods. For given pumping-to-thermal power ratio, the core output per unit heat transfer area is proportional to the merit index (N3/f)1/2. Stanton number, or dimensionless surface heat transfer coefficient, is Ns, and f is the friction factor.

摘要:

AbstractThree-region restructured fuel, with given thermal characteristics, may be represented by an effective conductivity integral function Y(T). For any fuel surface temperature Tsand linear heat generation rate q, the maximum fuel temperature Tvis found from the relation Yv- Ys= q. Region radii and molten fuel fraction appear in the groups qR2/R2land qF as functions of Yv- Ye.
