Computer simulators are widely used to train operators, technical and maintenance personnel at thermal and nuclear power plants (TPPs and NPPs). The use of training simulators provides power plant employees with the opportunity to gain valuable practical experience in case of emergency situations when technological processes deviate from normal operation. At the same time, operating personnel in the thermal automation and measurement (TAM) and process control systems (PCS) shops perform a vital function at the power plant. They ensure the performance monitoring and maintenance of all hardware and software components of the PCS of power unit. However, the training methods used at TPPs and NPPs for operating personnel in the TAM and PCS shops (theoretical training, on-the-job training for maintenance and operating personnel in the TAM and PCS shops) lag behind the current pace of industry development. The aim of the study is to develop an interactive simulator for training operational personnel of thermal automation and measurement shops and automated process control systems with virtual modeling of the field instrumentation and automation zone. The training system is supported by hardware and software located on the server side of the simulator running the Linux operating system. The programmer toolset is the specialized SIM-2000 software suite. Testing and debugging of the developed field-level equipment models (sensors and connection lines) have been conducted using the SimInTech dynamic simulation environment. A visualization subsystem for instrumentation and automation equipment (I&A) has been developed for TPP field equipment. This subsystem integrates developed models of sensors, devices, and actuators (AM) into modern computer simulators for power units, providing realistic visual modeling of field equipment. I&A device models have been developed that enable diagnostics of the condition of sensors and AM, adjusting their process connections to power lines, if necessary, as well as configuring them, checking their functionality, and monitoring their connections to the software and hardware suite and other devices. The obtained results enable comprehensive training for the operational shift personnel of the unit to solve the problem of control, maintenance, and troubleshooting of instrumentation and automation equipment.

The quality testing of traditional Chinese medicine injection (TCMI) provides quantitative indicators for its safety evaluation, improving quality control and reducing adverse reaction rates. However, no automated Microtox-based testing equipment currently exists globally, necessitating manual intervention in the entire process. To address this, our team developed an automated TCMI quality testing system using Microtox technology. By integrating manual workflows and standardizing reusable technologies, the instrument comprises three modules: a mixing-resuscitation module, a mechanical pipetting module, and a light intensity measurement module. Centralized computer control enables fully automated TCMI quality testing. Experimental results demonstrate strong consistency between manual and automated testing, with reduced human-induced measurement errors and enhanced data reliability for TCMI quality assessment.

A 6-MHz 16-bit waveform digitizer was evaluated for use in atmospheric differential absorption lidar (DIAL) measurements of ozone. The digitizer noise characteristics were evaluated, and actual ozone DIAL atmospheric returns were digitized. This digitizer could replace computer-automated measurement and control (CAMAC)-based commercial digitizers and improve voltage accuracy. Introduction The waveform digitizer is a critical component of lidar detection systems; it transforms the analog detector output into a digital signal by measuring the signal voltage in a discrete time interval determined by an external clock. The accuracy of the digital voltage level increases with the digitizer bit level. Technology has advanced to the point where 8- and 12-bit waveform digitizers are commercially available and commonly used in computer-automated measurement and control (CAMAC) crates, which are readily interfaced to computer systems. These systems have worked well for ground and aircraft-borne...

LLNL has successfully implemented a distributed computer control system for automated operation of an FN tandem accelerator. The control system software utilized is the Thaumaturgic Automated Control Logic (TACL) written by the Continuous Electron Beam Accelerator Facility and co-developed with LLNL. Using TACL, accelerator components are controlled through CAMAC using a two-tiered structure. Analog control and measurement are at 12 or 16 bit precision as appropriate. Automated operation has been implemented for several nuclear analytical techniques including hydrogen depth profiling and accelerator mass spectrometry. An additional advantage of TACL lies in its expansion capabilities. Without disturbing existing control definitions and algorithms, additional control algorithms and display functions can be implemented quickly. 5 refs., 1 fig.

Refineries, fuel depots, airports and storage terminals commonly use fluid level measurement in storage tanks. Different fluid level measurement techniques and devices differ in the inaccuracy of measurement results, costs, and company needs. In addition, these measurements seek reliability of measurement data, immediate response times, control in operations, oil movement, custody transfer and inventory control. The objective is to develop a computer system for measuring fluid levels in oil storage tanks, using ultrasonic and temperature sensors, creating a web application for an automated measurement system (SAM) for managing volumes of Petroleum. The study methodology is i) Analysis of measurement reports. ii) Selection of physical components of the computer system. iii) SAM algorithm design and web application, and iv) Validate the system. The SAM application developed in open source proposes functional modules for administration, control, security, management and monitoring of storage tanks, the status of physical components and generation of dynamic reports in real-time. The results show the control characteristics of storage tanks such as maximum and minimum volume, temperature, time, precise data records in less time than certain current computer structures.

An Analytical Chemistry Measurements Quality Control Program assures the reliability of analytical measurements performed at the Barnwell Nuclear Fuel Plant. The program includes training, methods quality control, replicate samples and measurements, mass measurements, interlaboratory sample exchanges, and standards preparation. This program has been designed to meet the requirements of 10CFR70.57. Portions of the program have been automated by using a PDP 11/35 computer system to provide features which are not readily available in manual systems. These include such items as realtime measurement control, computer calculated bias and precision estimates, various surveillance applications, and evaluation of measurement system variables. The efficiency of the computer system has been demonstrated in gathering and assimilating the results of over 1100 quality control samples during a recent cold chemical checkout campaign. These data were used to determine equations for predicting measurements reliability estimates; to evaluate measurement performance of the analysts, equipment, and measurement period; and to provide directions for chemistry methods modifications and additional training requirements. A procedure of replicate sampling and measuring provides random error estimates. The analytical chemistry measurement quality control activities during the campaign represented about 10% of the total analytical chemistry effort.
