Equilibration of Leachants with Basalt Rock for Repository Simulation Tests

Description: In a nuclear waste repository in basalt, the groundwater will have a low redox potential (Eh) which may affect the leach rate of SRP waste glass. Accurate laboratory simulations of conditions in a basalt reposition must maintain low Eh values throughout the course of the experiment. In this report, important parameters affecting the ability of basalt to maintain appropriate Eh-pH conditions are examined, in particular basalt type and groundwater simulation.

Analytical study and tracking simulations of the beam-beam compensation at Tevatron

Description: Head-on and long-range induced tunespread of about 0.025 in the Tevatron collider at Run II (together with the increased strength of the resonances) can significantly deteriorate the {bar p} lifetime and the collider luminosity. It was proposed to employ the so-called Tevatron Electron Lenses (TEL) to compress the beam-beam footprint and eliminate completely the bunch-to-bunch tunespread (PACMAN effect) for small amplitude particles. The first lens has been recently installed and tested [1]. Th… more

Proposal for Creating a Pocket of Innovation and Adaptability Within a Bureaucratic Enterprise

Description: A conceptual framework is developed that is based on a behavioral model for organizations that rely upon innovation and adaptability for their survival in the market place. The model supports the assertion that change efforts aimed at performance improvement need a systems approach because contributions to an organization's performance cross functional lines and are systemic in nature. The model implies four conclusions for a unit trying to effectuate change within a greater bureaucracy. First,… more

Beam-beam interactions at the Tevatron in Run IIa

Description: The Tevatron in Run IIa will operate with three trains of twelve bunches each. The impact of the long-range interactions on beam stability will be more significant compared to Run I. We study these beam-beam interactions (head-on and long-range) with particle tracking using two different codes. The model includes machine nonlinearities such as the field errors of the Interaction Region quadrupoles and the chromaticity sextupoles. Tune footprints and dynamic apertures are calculated for differen… more

Relative Release Rates of Nitrate, Tc, Cs and Sr from Saltstone

Description: The relative release rates of nitrate, cesium, strontium, and technetium have been measured from saltstone and soilcrete (salt-stone containing soil) under saturated conditions. These are the first measurement of radionuclide release rates from saltstone, and confirm the assumptions used earlier in mathematical modeling. Both saltstone and saltcrete have comparable leach rates for nitrate and pertechnetate anions. Cesium and strontium are more strongly held in both materials, but show differenc… more
