Cast Stone Formulation At Higher Sodium Concentrations
A low temperature waste form known as Cast Stone is being considered to provide supplemental Low Activity Waste (LAW) immobilization capacity for the Hanford site. Formulation of Cast Stone at high sodium concentrations is of interest since a significant reduction in the necessary volume of Cast Stone and subsequent disposal costs could be achieved if an acceptable waste form can be produced with a high sodium molarity salt solution combined with a high water to premix (or dry blend) ratio. The objectives of this study were to evaluate the factors involved with increasing the sodium concentration in Cast Stone, including production and performance properties and the retention and release of specific components of interest. Three factors were identified for the experimental matrix: the concentration of sodium in the simulated salt solution, the water to premix ratio, and the blast furnace slag portion of the premix. The salt solution simulants used in this study were formulated to represent the overall average waste composition. The cement, blast furnace slag, and fly ash were sourced from a supplier in the Hanford area in order to be representative. The test mixes were prepared in the laboratory and fresh properties were measured. Fresh density increased …

Center for Momentum Transport and Flow Organization in Plasmas and Magnetofluids (CMTFO)
The CMTFO funding partially supports a junior researcher and a graduate student at UCI. During this project, we have further developed the global gyrokinetic particle code GTC to study the momentum transport in tokamak driven by electrostatic ion temperature gradient (ITG) turbulence [1] with kinetic electrons and by collisionless trapped electron mode (CTEM) turbulence [2]. We have also upgraded GTC for fully electromagnetic simulation and for linear plasma configuration with verification and validation of the electron temperature gradient (ETG) turbulence in Columbia Linear Machine. The followings are the highlights on the physics results reported in the key publications of this project.

General Services Administration: GSA Should Clarify Its Reporting Exemption and Collect Additional Data on Executives' Use of Aircraft for Nonmission Purposes
A letter report issued by the Government Accountability Office with an abstract that begins "The exemption in General Services Administration (GSA) regulations that allows intelligence agencies not to report unclassified data on senior federal official travel for nonmission purposes is not consistent with executive branch requirements, and GSA has not provided a basis for deviating from these requirements. Specifically, executive branch documents—including Office of Management and Budget (OMB) Circular A-126, OMB Bulletin 93-11, and a 1993 presidential memorandum to the heads of all executive departments and agencies—require agencies to report to GSA, and for GSA to collect data, on senior federal official travel on government aircraft for nonmission purposes, except for trips that are classified. As a result, GSA is not collecting all specified unclassified data as directed, and GSA has not provided a basis for deviating from executive branch requirements. Identifying an adequate basis for the intelligence agency reporting exemption or removing the exemption from its regulations if a basis cannot be identified could help GSA ensure its regulations for senior federal official travel comply with executive branch requirements."

Multi-Hybrid Power Vehicles with Cost Effective and Durable Polymer Electrolyte
Anima Bose, the principal investigator of the project, originally proposed to develop composite membranes to operate PEMFCs at much higher temperatures than 80{degrees}C and to alleviate the flooding problems often encountered in Nafion menmbrane containing fuel cells. The PI has successfully created composite membranes by blending small quantities of octasilane-poss (OSP) with Nafion. The composite membranes exhibited temperature tolerance up to 110{degrees}C without scarifying cell performance as determined by polarization curves and proton conductivity measurements. These membranes also exhibited superior water management performance as evident from the lack of flooding. Furthermore, these fuel cells performed well under reduced humidities. Structural and thermal analyses revealed that these Nafion-octasilane composite membranes are homogenous at concentrations up to 3 wt% of the OSP and that the siloxane offers additional thermal stability.
