Ultra has developed a complete range of neutron flux instruments for monitoring and protection applications in the nuclear industry. The range includes pulse counting, Campbell processing, log DC and linear DC measurements. These instruments are available as individual items or as a complete flux monitoring system. All of the instruments have been developed using a modular approach which provides a high degree of flexibility for configuration changes to meet specific customer requirements. They are designed to operate in nuclear power plant environments, complying with stringent electromagnetic compatibility standards. Fail-safe circuit architectures employing conservatively rated analogue components are used to achieve the high levels of safety and reliability demanded by the target safety critical applications. They have undergone extensive qualification and have been operating very effectively for many years with full regulatory approval. This operational experience makes the instruments well suited for new installations and upgrades.
The Instruments are designed to achieve high levels of safety and reliability. In particular, high integrity fail-safe circuit architectures are used where necessary to meet the demands of the applications. The instruments have undergone extensive safety evaluation and FMEA data can be provided on request. They are modular which facilitates maintenance and routine testing. A complete range of test equipment is available to support maintenance and repair activity. In addition, after sales support options are available to meet customers' specific needs.
