Material Accounting

The Nuclear Material Accounting (NMA) system is one of the main safeguards measures to detect the existence of nuclear material diversion. It has become more important for large reprocessing facilities to apply Near Real Time Accountancy (NRTA) system based on NMA and statistical techniques to meet quantitative and timeliness goals. It is also important to quantitatively evaluate the performance of NMA system including NRTA from the standpoints of Safeguards and Security by Design (SSBD) prior to construction of nuclear-material-handling facilities. Such evaluation improves safeguards effectiveness and efficiency. Modeling and Simulation (M&S) work is a good way to evaluate performance for various NMA systems and to determine the optimal one among different options. For these purposes, in the present study, the PYroprocessing Material flow and MUF Uncertainty Simulation+ (PYMUS+) code, which uses evaluation algorithms to calculate many safeguards factors such as MUF uncertainty, detection probability, and others, was developed. According to a previous report, the PYMUS code, the predecessor of PYMUS+, can calculate MUF uncertainties only for a fixed model having 10 tHM/year, whereas the PYMUS+ code can additionally calculate detection probabilities according to diverse nuclear diversion scenarios as well as MUF uncertainties. The most important feature of the PYMUS+ code is its capability to evaluate many process and NMA system model options that a user wants to evaluate. Furthermore, a user can make a static process model having simplicity and a matching NMA model based on the PYMUS+ code regardless of facility throughput and is not even required to have professional programming knowledge. In the present work, some intercomparative studies were conducted to verify the M&S techniques applied in this code. It is expected that this code will be a useful tool for evaluation of NRTA system of pyroprocessing and other reprocessing facilities.

Described as units developing public policies in a design-oriented manner, Policy Labs are tasked to innovate to gain in policy effectiveness and efficiency. However, as public policymaking is a context-dependent activity, the way in which these novel organisations operate significantly differs. This study discusses the emergence of design approaches for policy innovation. The purpose is to map how Policy Labs in Europe introduce design approaches at distinct stages of the policymaking cycle. For this study, 30 organisations in Europe operating at various levels of government were surveyed. Based on the public policymaking process model, it investigates which design methods are Policy Labs deploying to innovate public policies. The study exposed a gap in the awareness of the utilised methods' nature. It also showed that the use of design methods is of less importance than the introduction of design mindsets for public policy innovation, namely ‘user-centredness’, ‘co-creation’, and ‘exploration’.

Community Service is one part of the direct contribution from academics, in this case the Faculty of Economics and Business, Trisakti University to the community. On this occasion the Trisakti University FEB team had the opportunity to provide training on Material Flow Cost Accounting (MFCA) for MSMEs. This training is considered important considering that the understanding of MSME actors in terms of the flow cost of material is still very minimal, so that in the implementation of their business there are still very few who apply it in the production process. This training aims to educate MSME actors in terms of flow cost accounting for the use of their production materials, MSMEs can sort out the types and types of materials to be used so as to increase the effectiveness and efficiency of production to increase sales and business profits. PKM training will be carried out using an online method considering the conditions of the COVID-19 pandemic, which until now has not allowed face-to-face/off-line training. The output of this PKM will be published to the public so that it can provide wider benefits.

The layout applied on the production floor of the Department of Mechanic of PT. Jefta Prakarsa Pratama is not considered as an optimal layout. The reason triggered this optimal level, are some backtrack movements that reduce the effectiveness and efficiency of material handling activities. This research refers to two types of calculation methods. First, manual calculation, which is rectilinear distance measure. Second, computerized calculation, which is Quantitative Systems (QS) software. There are three critical criterias referenced in this research, i.e. straight flow of material, more minimal backtrack movement, and more minimal material moving distance. The iteration results using QS software are translated into block layout and then are made as a proposed layout. The rectilinear calculations performed manually are intended to calculate the total of material moving distance. The data processing obtained a re-layout solution which is more optimal for the production floor of the Department of Mechanic, because it could reduce backtrack distance by 75.28% and the material moving distance by 30.03%. The implementation of the proposed layout is expected to reduce the time of material moving activity on the production floor of the Department of Mechanic, so that the material moving process could run more effectively and efficiently.

This paper describes the current pressure protection program at Savannah River Site (SRS), a Department of Energy chemical processing and nuclear material handling facility in Aiken, South Carolina. It gives a brief description of the design requirements based on ASME, API, CGA, and ASHRAE Codes. Equipment and systems requiring pressure protection at SRS are primarily pressure vessels, steam stations, process chemical systems, refrigerant and cryogenic systems and other air or gas systems. It is understood that any pressure protection program is built on five fundamental areas of responsibility: procurement, verification, registration, inspection, and repair. This paper focuses on the existing process of facility pressure protection evaluation for code compliance followed by identification of failure scenarios and system design requirements, valve selection and sizing, and verification record generation. Improvements to this process are recognized and discussed. They include the development of a computer program to perform pressure protection evaluation and generate verification records. The software would process all applicable pressure protection calculations using improved methodologies. All relevant data required would be accessible within the program. Pressure safety relief device attributes and system parameters would be displayed. The computer program would enhance design consistency, improve quality and plant safety, and make the pressure protection verification process more efficient and cost effective.

Manual Tasks

Nuclear material processing operations present numerous challenges for effective automation. Confined spaces, hazardous materials and processes, particulate contamination, radiation sources, and corrosive chemical operations are but a few of the significant hazards. However, automated systems represent a significant safety advance when deployed in place of manual tasks performed by human workers. The replacement of manual operations with automated systems has been desirable for nearly 40 years, yet only recently are automated systems becoming increasingly common for nuclear materials handling applications. This paper reviews several automation systems which are deployed or about to be deployed at Los Alamos National Laboratory for nuclear material handling operations. The needs that resulted in the development of these systems can be found throughout the nuclear industry. Highlighted are the current social and technological challenges faced in deploying automated systems into hazardous material handling environments and the opportunities for future innovations.

The binder force in sheet metal forming controls the material flow into the die cavity. Maintaining precise material flow characteristics is crucial for producing a high-quality stamped part. Process control can be used to adjust the binder force based on tracking of a reference punch force trajectory to improve part quality and consistency. The purpose of this paper is to present a systematic approach to the design and implementation of a suitable multi-input multi-output (MIMO) process controller. An appropriate process model structure for the purpose of controller design for the sheet metal forming process is presented and the parameter estimation for this model is accomplished using system identification methods. This paper is based on original experiments performed with a new variable blank holder force (or variable binder force) system that includes 12 hydraulic actuators to control the binder force. Experimental results from a complex-geometry part show that the MIMO process controller designed through simulation is effective.

Introduction of new technology (technology implementation) within an organisation can have wide reaching implications, beyond the effectiveness and efficiency savings that are typically the aim of such an endeavour. The ‘Health and Prognostic Assessment of Railway Assets for Predictive Maintenance’ project developed a prognostic tool, which aimed to support enhancement of the London underground’s remote condition monitoring system to support change from reactive and preventative to predictive maintenance, in order to increase effectiveness and efficiency and reduce lost customer hours. This paper investigates the organisational challenges associated with the introduction of such a tool. The paper describes the approach adopted to model the extant maintenance processes (focusing on role mapping) and associated organisational structures which revealed issues such as unclear processes, poor communication and data sharing links and problems with delineation of responsibility for decision making. It also describes the development of a new maintenance process model that incorporates the additional functionality of the new prognostic tool, taking in to account changes of roles, responsibilities, organisational processes and activities.
