Instrument protection system targets nuclear industry

15th August 2013


Hima-Sella is to develop a two-tier, fail-safe Instrument Protection System to include the EMPHASIS-approved Planar4 logic solver

Systems integration specialist Hima-Sella is to develop and provide a two-tier, fail-safe Instrument Protection System (IPS), for use in the nuclear industry, with the primary level of protection implemented using HIMA’s Planar4 solid-state logic solver. Earlier this year, and under the rigorous EMPHASIS assessment methodology, the modules of the Planar4 logic solver secured approval for use in safety systems in the nuclear industry.

The secondary level of protection within the IPS will be implemented using plug-in relay logic. Also, and in accordance with IEC 61508, the solutions for the two IPS levels will be developed by two independent engineering teams, using separate production facilities, within Hima-Sella.

Through interfacing with temperature, pressure and other sensors, as well as valve actuators and pumps, the two-tier IPS will be able to perform automatic emergency shut downs as well as respond to manual trips. The IPS project also includes the provision of a number of HMI matrix panels, to enable operators to view and respond to process and alarm conditions.
