TECHNOLOGY ROADMAPPING FOR IAEA SEALS.

Description: In the fall of 2002, the U.S. Support Program (USSP) initiated an effort to define a strategy or ''roadmap'' for future seals technologies and to develop a generalized process for planning safeguards equipment development, which includes seals and other safeguards equipment. The underlying objectives of the USSP include becoming more proactive than reactive in addressing safeguards equipment needs, helping the IAEA to maintain an inventory of cost-effective, reliable, and effective safeguards equipment, establishing a long-term planning horizon, and securing IAEA ownership in the process of effective requirements definition and timely transitioning of new or improved systems for IAEA use. At an initial workshop, seals, their functions, performance issues, and future embodiments were discussed in the following order: adhesive seals, metal seals, passive and active loop seals, ultrasonic seals, tamper indicating enclosures (including sample containers, equipment enclosures, and conduits). Suggested improvements to these technologies focused largely on a few themes: (1) The seals must be applied quickly, easily, and correctly; (2) Seals and their associated equipment should not unduly add bulk or weight to the inspectors load; (3) Rapid, in-situ verifiability of seals is desirable; and (4) Seal systems for high risk or high value applications should have two-way, remote communications. Based upon these observations and other insights, the participants constructed a skeletal approach for seals technology planning. The process begins with a top-level review of the fundamental safeguards requirements and extraction of required system features, which is followed by analysis of suitable technologies and identification of technology gaps, and finally by development of a planning schedule for system improvements and new technology integration. Development of a comprehensive procedure will require the partnership and participation of the IAEA. The presentation will include a description of the roadmapping approach developed for safeguards technologies and an overview of the initial seals workshop results.

Scaling Rules for Pre-Injector Design

Description: Proposed designs of the prebunching system of the NLC and TESLA are based on the assumption that scaling the SLC design to NLC/TESLA requirements should provide the desired performance. A simple equation is developed to suggest a scaling rule in terms of bunch charge and duration. Detailed simulations of prebunching systems scaled from a single design have been run to investigate these issues.

THE ESTABLISHMENT OF A U.S. SUPPORT PROGRAM INTERSHIP PROGRAM.

Description: In 2002, the U.S. Support Program to IAEA Safeguards established a program of one-year paid internships with the IAEA Department of Safeguards for students and recent graduates. Six interns are currently working with the IAEA in software development and information collection activities. The program is administered through the International Safeguards Project Office (ISPO) at Brookhaven National Laboratory (BNL). Software development assignments were considered to be most feasible because of the considerable abilities of many computer science students after a few years' education. Candidates in information science were also recruited because of an existing internship program managed by the Monterey Institute of International Studies. ISPO recruited students from US. colleges and other sources. Applications were collected and provided to the IAEA for review and selection. SGIT then identified the best applicants and, after confirming their intention to accept the position, tailored assignments based on their qualifications. Before the assignments started, ISPO conducted an orientation to provide the interns with information to ease their transition into working with the IAEA and living in Vienna. Four interns began their assignments in software development in June 2002 and two others began their assignments in information collection in July and August. The IAEA, the interns, and the Subgroup on Safeguards Technical Support have found the assignments to be beneficial. The internship program provides additional staff to the IAEA at low cost to the USSP, introduces young professionals to careers in the nuclear industry and international civil service, and provides the IAEA access to U.S. academic institutions. In 2003, the program will be expanded to include engineering and technical writing in support of the Division of Safeguards Technical Services. The paper will discuss the recruitment and selection of interns and the administration of the program.

DEVELOPMENT AND TESTING OF PROCEDURES FOR CARRYING OUT EMERGENCY PHYSICAL INVENTORY TAKING AFTER DETECTING ANOMALY EVENTS CONCERNING NM SECURITY.

Description: In the State Scientific Center of Russian Federation - Institute of Physics and Power Engineering (SSC RF-IPPE, Obninsk), which is under Minatom jurisdiction, the procedures for carrying out emergency physical inventory taking (EPIT) were developed and tested in cooperation with the Brookhaven National Laboratory (USA). Here the emergency physical inventory taking means the PIT, which is carried out in case of symptoms indicating a possibility of NM loss (theft). Such PIT often requires a verification of attributes and quantitative characteristics for all the NM items located in a specific Material Balance Area (MBA). In order to carry out the exercise, an MBA was selected where many thousands of NM items containing highly enriched uranium are used. Three clients of the computerized material accounting system (CMAS) are installed in this MBA. Labels with unique (within IPPE site) identification numbers in the form of digit combinations and an appropriate bar code have been applied on the NM items, containers and authorized locations. All the data to be checked during the EPIT are stored in the CMAS database. Five variants of anomalies initiating EPIT and requiring different types of activities on EPIT organization are considered. Automatic working places (AWP) were created on the basis of the client computers in order to carry out a large number of measurements within a reasonable time. In addition to a CMAS client computer, the main components of an AWP include a bar-code reader, an electronic scale and an enrichment meter with NaI--detector--the lMCA Inspector (manufactured by the Canberra Company). All these devices work together with a client computer in the on-line mode. Special computer code (Emergency Inventory Software-EIS) was developed. All the algorithms of interaction between the operator and the system, as well as algorithms of data exchange during the measurements and data comparison, are implemented in ...
