RADIOISOTOPE AND RADIATION APPLICATIONS QUARTERLY PROGRESS REPORT. SECTION I. USE OF INTRINSIC RADIOACTIVE TRACERS FOR PROCESS CONTROL. SECTION II. RADIATION-INDUCED GRAFT-POLYMERIZATION STUDIES
Research was continued in the areas of intrinsic radioactive tracers for industrial process control and the influence of structural factors in radiation- induced graft polymerization. The use of in-process isotope neutron soarces to produce short-lived radiotraces is discussed. A 10c Po--Be neutron source was obtained for exploratory experiments. The design and construction of a neutronsource storage shield and an activatioa-cell holder are underway. The effect of structural factors oii the eIficiency of free-radical site formation in acrylate and methacrylate polymers was emphasized. Site measurements versus dose were made for poly-n-hexylmethacrylate. Two additional methods for measuring free-radical conceiitrations, a chemical method employing diphenylpicrylhydrazyl and hydroquinone and a method based on molecular-weight decreases, were developed. The grafting studies were continued. (M.C.G.)

THE EFFECTS OF INTERNAL HEAT GENERATION ON POT CALCINATION RATES FOR RADIOACTIVE WASTES
Methods by which the radial deposition mechanism was determined in experiments with simulated waste solutions are reviewed. Based on this mechanism, an expression for the rate of solid deposition with internal heat generation was developed by a combined heat and material balance. A sample calculation for Purex waste showed that a moderate heat generation rate of 5000 Btu/hr/ft/sup 3/ would decrease the time to fill a 12-in.-dia calcination vessel from 78 to 55 hr. For the calcination stage of the process in which the deposited solids are heated in the absence of a liquid phase, a solution was developed for the equation of heat transfer with the temperature profile from the solid deposition stage as an initial condition. For the example Purex waste with a heat generation rate of 5000 Btu/hr ft/sup 3/, less than 15 min would be required for calcination, compared to about 8 hr in experiments with simulated wastes.

Evaluation of Effectiveness of the Turco Low Profile Turbulator Reg Sign
This document discusses a turbulator which utilizes a heated chemical bath to reduce smearable contamination from small parts and tools. It is comprised of two agitators programmed to automatically alternate the flow of the cleaning solution within the tank in four separate and distinct high velocity flow patterns allowing access to the entire surface area of the part or tool being decontaminated. The turbulator is being evaluated to determine if agitation increases the effectiveness of waste minimization. Testing of the turbulator consisted of evaluation of the Sludgetrap Containment, Tool Cleaning Demonstration, and Coupon Testing. Results so far are that the sludgetrap is effective in containing particles the size of sand, agitation increases the effectiveness of the turbulator, abrasives can replace detergents for waste minimization, and Inconel 625 is more difficult to clean than Type 3041 Stainless Steel.

Evaluation of low activation vanadium alloys for structural material in a fusion reactor
The V-7.2Cr-14.5Ti, V-9.2Cr-4.9Ti, V-9.9Cr-9.2Ti, V-13.5Cr-5.2Ti, V-4.1Cr-4.3Ti, Vanstar-7, V-4.6Ti, V-17.7Ti, and V-3.1Ti-(0.5-1.0)Si alloys were evaluated for use as structural material in a fusion reactor. The alloys were evaluated on the basis of their yield strength, swelling resistance, resistance to hydrogen and irradiation embrittlement, and compatibility with a lithium reactor coolant. On the basis of these evaluations, the V-7.2Cr-14.5Ti, V-9.2Cr-4.9Ti, V-9.9Cr-9.2Ti, V-13.5Cr-5.2Ti, Vanstar-7, and V-3.1Ti-(0.5-1.0)Si alloys are considered unacceptable for structural material in a fusion reactor, whereas the V-4.1Cr-4.3Ti, V-4.6Ti, and V-17.7Ti alloys are recommended for more intensive evaluation. The V-7Cr-5Ti alloy may have the optimum combination of strength, DBTT, swelling rate, and lithium dissolution rate for a structural material in a fusion reactor. 4 refs., 6 figs., 4 tabs.

Project Bioshield: Actions Needed to Avoid Repeating Past Problems with Procuring New Anthrax Vaccine and Managing the Stockpile of Licensed Vaccine
A letter report issued by the Government Accountability Office with an abstract that begins "The anthrax attacks in September and October 2001 highlighted the need to develop medical countermeasures. The Project BioShield Act of 2004 authorized the Department of Health and Human Services (HHS) to procure countermeasures for a Strategic National Stockpile. However, in December 2006, HHS terminated the contract for a recombinant protective antigen (rPA) anthrax vaccine because VaxGen failed to meet a critical contractual milestone. Also, supplies of the licensed BioThrax anthrax vaccine already in the stockpile will start expiring in 2008. GAO was asked to identify (1) factors contributing to the failure of the rPA vaccine contract and (2) issues associated with using the BioThrax in the stockpile. GAO interviewed agency and industry officials, reviewed documents, and consulted with biodefense experts."

Nuclear Safety: Department of Energy Needs to Strengthen Its Independent Oversight of Nuclear Facilities and Operations
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy (DOE) oversees contractors that operate more than 200 "high-hazard" nuclear facilities, where an accident could have serious consequences for workers and the public. DOE is charged with regulating the safety of these facilities. A key part of DOE's self-regulation is the Office of Health, Safety and Security (HSS), which develops, oversees, and helps enforce nuclear safety policies. This is the only DOE safety office intended to be independent of the program offices, which carry out mission responsibilities. This report examines (1) the extent to which HSS meets GAO's elements of effective independent nuclear safety oversight and (2) the factors contributing to any identified shortcomings with respect to these elements. GAO reviewed relevant DOE policies, interviewed officials and outside safety experts, and surveyed DOE sites to determine the number and status of nuclear facilities. GAO also assessed oversight practices against the criteria for independent oversight GAO developed based on a series of reports on DOE nuclear safety and discussions with nuclear safety experts."

Centers for Medicare and Medicaid Services: Deficiencies in Contract Management Internal Control Are Pervasive
A letter report issued by the Government Accountability Office with an abstract that begins "As a result of internal control deficiencies discussed in GAO's 2007 report on certain contracts at the Centers for Medicare and Medicaid Services (CMS), GAO was asked to identify the extent to which CMS (1) implemented effective control procedures over contract actions, and (2) established a strong control environment for contract management. GAO used a statistical random sample of 2008 CMS contract actions (including contract awards and modifications) to assess CMS internal control procedures. The results were projected to the population of 2008 CMS contract actions. GAO also determined the extent to which CMS implemented recommendations GAO made in 2007 to improve internal control over contracting and payments to contractors. GAO reviewed contract file documentation and interviewed senior acquisition management officials."

Defense Critical Infrastructure: Actions Needed to Improve the Identification and Management of Electrical Power Risks and Vulnerabilities to DOD Critical Assets
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) relies on a global network of defense critical infrastructure so essential that the incapacitation, exploitation, or destruction of an asset within this network could severely affect DOD's ability to deploy, support, and sustain its forces and operations worldwide and to implement its core missions, including those in Iraq and Afghanistan as well as its homeland defense and strategic missions. In October 2008, DOD identified its 34 most critical assets in this network--assets of such extraordinary importance to DOD operations that according to DOD, their incapacitation or destruction would have a very serious, debilitating effect on the ability of the department to fulfill its missions. Located both within the United States and abroad, DOD's most critical assets include both DOD- and non-DOD-owned assets. DOD relies overwhelmingly on commercial electrical power grids for secure, uninterrupted electrical power supplies to support its critical assets. DOD is the single largest consumer of energy in the United States, as we have noted in previous work. According to a 2008 report by the Defense Science Board Task Force on DOD's Energy Strategy, DOD has traditionally assumed that …

Homeland Security: Greater Attention to Key Practices Would Improve the Federal Protective Service's Approach to Facility Protection
A letter report issued by the Government Accountability Office with an abstract that begins "There is ongoing concern about the security of federal buildings and their occupants. The Federal Protective Service (FPS) within the Department of Homeland Security (DHS) is responsible for providing law enforcement and related security services for nearly 9,000 federal buildings under the control and custody of the General Services Administration (GSA). In 2004, GAO identified a set of key protection practices from the collective practices of federal agencies and the private sector that included: allocating resources using risk management, leveraging technology, and information sharing and coordination. As requested, GAO determined whether FPS's security efforts for GSA buildings reflected key practices. To meet this objective, GAO used its key practices as criteria, visited five sites to gain firsthand knowledge, analyzed pertinent DHS and GSA documents, and interviewed DHS, GSA, and tenant agency officials."

Nuclear Weapons: National Nuclear Security Administration Needs to Better Manage Risks Associated with Modernization of Its Kansas City Plant
A letter report issued by the Government Accountability Office with an abstract that begins "Built in 1943, the Kansas City Plant (KCP)--the National Nuclear Security Administration's (NNSA) primary production plant for manufacturing nonnuclear components of nuclear warheads and bombs--is to be modernized because of its age and the high cost of maintenance and operation. Among other changes, NNSA plans to relocate KCP to a new facility and increase components obtained from external suppliers from about 54 to 70 percent. KCP's continued supply of these components is essential for maintaining a reliable nuclear weapons stockpile. GAO was asked to determine (1) how KCP developed plans for modernization, (2) actions KCP has taken to ensure uninterrupted production of components, and (3) actions KCP has taken to address the risks of outsourcing. GAO reviewed planning documents and met with officials from NNSA, KCP, and Sandia National Laboratories, which designs many of the components produced at KCP."

U.S. Department of Justice: Information on Employment Litigation, Housing and Civil Enforcement, Voting, and Special Litigation Sections' Enforcement Efforts from Fiscal Years 2001 through 2007
A letter report issued by the Government Accountability Office with an abstract that begins "The Civil Rights Division (Division) of the Department of Justice (DOJ) is the primary federal entity charged with enforcing federal statutes prohibiting discrimination on the basis of race, sex, disability, religion, and national origin. GAO was asked to review the Division's enforcement efforts. This report addresses the activities the Division undertook from fiscal years 2001 through 2007 to implement its enforcement responsibilities through four of its sections (1) Employment Litigation, (2) Housing and Civil Enforcement, (3) Voting, and (4) Special Litigation. To conduct our review, GAO analyzed data on cases filed in court and matters (e.g., a referral or allegation of discrimination) investigated. To supplement this analysis, GAO also reviewed a sample of closed matter files (about 210 of 5,400). GAO randomly selected matters investigated under different statutes for each section and considered the government role (e.g., plaintiff or defendant) and type of issues investigated (e.g., the nature of the alleged discrimination or violation) to ensure that the sample reflected the breadth of the work and practices of each section. While not representative of all closed matters, the sample results provided examples of why matters were …
