چکیده

The Spallation Neutron Source, Target Test Facility is a full-scale replica of the mercury-target flow loop and the target hot cell, used to study flow the characteristics of a large scale mercury system, and develop remote handling techniques and tools for replacing target system components. During the past year, prototypic equipment was added to the loop to simulate actual flow conditions and to compare empirical and analytical data. These included a welded-tube heat exchanger, an electromagnetic flow meter, a hydraulically prototypic target, and numerous pressure sensors. Outside of the loop enclosure, tests were done on a new seal configuration to assess leak tightness and remote handling features. In addition, testing of remotely operated tools and lift fixtures, remote replacement of utility pipes, and remote handling of the target module were performed.

A Tunned-parameter Hybrid Algorithm for Dynamic Facility Layout Problem with Budget Constraint using GA and SAA

A facility layout problem is concerned with determining the best position of departments, cells, or machines on the plant. An efficient layout contributes to the overall efficiency of operations. It’s been proved that, when system characteristics change, it can cause a significant increase in material handling cost. Consequently, the efficiency of the current layout decreases or is lost and it ...

Development of the Sns External Antenna H Ion Source

The U.S. Spallation Neutron Source (SNS) is an accelerator-based, pulsed neutron-scattering facility currently in the process of ramping up neutron production. To meet present and future beam current and reliability requirements we are developing an RF-driven, H ion source based on a ceramic aluminium nitride (AlN) plasma chamber surrounded by an external RF antenna. This report recounts the de...

Generalizing Java RMI to Support Efficient Group Communication

This paper presents a generalization of the Java Remote Method Invocation model (RMI) providing an efficient group communication mechanism for parallel programming. In our Group Method Invocation model (GMI), methods can be invoked on a local object, on a remote object or on a group of objects (possibly with personalized parameters). Likewise, result values and exceptions can be returned normal...
