Accelerator driven fast nuclear reactors cooled by lead-bismuth eutectic (LBE) are developed for transmuting long-lived radionuclides in spent fuel. Due to the nature of coolant, operating reactor will result a production 210Po neutron capture. Understanding behavior this highly radiotoxic nuclide event failure window separating evacuated proton beam guide from core is required safety assessmen...

Accumulation and cellular distribution of '̂Am, 2'0Po, and "Opb were studied in the marine diatom Thalassiosira pseudonana and the marine green alga Dunaliella tertiolecta, Both species concentrated Am, Po, and Pb from artificially spiked cultures, resulting in wet weight concentration factors of approximately 1 to 4 X lo5 for '̂Am, 3 to 7 X lo4 for 210Po, and 5 to 17 X lo3 for "OPb. These concen...

Dosimetry of nonuniformly distributed 210Po,67Cu, and 123I was evaluated for a single cell, modeled as a homogeneous unity-density sphere with a radius of 7.7 mum, which is typical of a B-cell lymphoma cell. A Visual Basic program was used to calculate S factors and radial absorbed dose-rate profiles for these radionuclides, taking into account their individual radiation energy spectra. The res...

A relativistic nuclear energy density functional is developed, guided by two important features that establish connections with chiral dynamics and the symmetry breaking pattern of low-energy QCD: a) strong scalar and vector fields related to inmedium changes of QCD vacuum condensates; b) the longand intermediate-range interactions generated by one-and two-pion exchange, derived from in-medium ...
