After years of effort perfecting our Distributed Control System (DCS) we are proud to announce that the Nuclear Regulatory Commission (NRC) has approved the Doosan HF Controls HF6000 product line for use in nuclear power plants in the United States.  Doosan HF Controls will be receiving official notice shortly of the final acceptance of the Safety Evaluation and Draft Safety Evaluation comments from the NRC. This is a great day for HF Controls and the American nuclear power industry.

Already in service in numerous nuclear plants around the world, NRC approval of the HF6000 system gives aging American plants a new path towards safe operation with modern controls, providing Americans with clean, reliable electricity into the future.

The first of a large number of Sequence of Events (SOE) rack systems finished Final Acceptance Testing and will ship this week. This system is capable of resolving event times to less than 1 mSec. Each SOE processor is capable of storing up to 32,000 events on 16 input channels with the rack supporting up to eight SOE processors.

HF Controls has completed work on a new signal amplifier input card to be used at nuclear power plant Units 1 & 2 in Shin Ulchin, South Korea.  This new card will receive extremely small signals (~3 micro-amps) from the neutron flux detectors in the reactor core and amplify them for display and control in the safety system monitoring the core of the nuclear power plant.  These amplifier cards will ship to the site in the 1st quarter of 2011.

Today, HFControls is proud to announce that our HF6000 series Safety Control System has received SIL 3 certification for Triple Modular Redundant (TMR) from TUVRheinland and SIL 2 certification for Double Modular Redundant (DMR)! The HF6000 Safety Control System is now qualified for mission critical or safety control systems, such as in utilities, petrochemical and pulp and paper mill industries.

HF Controls completed work on creating the new driver for the Safety Data Network system for South Korean nuclear power plants Shin Ulchin Units 1 & 2.  Utilization of the new interface driver will take place in December of 2010.

HFControls has just shipped the second of three upgrade systems for the NRG Parrish, Texas power plants.  The existing AFS systems were installed in 1987 and have been in continuous operation.  Each upgrade replaces the individual loop controller CPU with modern CPU boards, converts the programming from a Patch Panel system to a Boolean form, upgrades the entire communication network and replaces the old Starburst Keyboard operator interface with new high-definition LCD screens with updated graphics.  Unit 6 equipment shipped in May of 2009, Unit 7 in September of 2010 and Unit 5 will ship in February of 2011.

The Alternate A/C Diesel Generator Control (AACDG) systems for Units 1 & 2 at both the Ulchin and Younggwang nuclear power plant sites (South Korea) have finished Site Acceptance status in September, 2010.

HFC was awarded a multi-million dollars project for performing Commercial Grade Item Dedication for over 70 different types of items.  These items include switches, cables, monitors, commercial PC, software, etc., to be used for safety-critical applications in nuclear power plants.

HF Controls has completed work on a new Sequence of Event (SOE) system with 1 mSec resolution to be installed at Shin Ulchin (South Korea) nuclear power plants Units 1 & 2 which supplements their existing Safety Control System.  This equipment will ship in December of 2010.

HF Controls completed the direct replacement of existing CPU boards at the South Korean Younggwang nuclear power plant, Units 3 & 4 in March of 2010.  The existing AFS system was commissioned in 1994 and used AFS-SBC-01 CPU boards for all the loop controls.  HF Controls developed a new surface mount technology FPGA 8085 CPU compatible board, allowing our customer to simply remove more than 100 of the old CPU boards and directly replace them with the modern technology board, saving them considerable down time and money over any more extensive upgrade to their system.

In October and December 2009, US NRC conducted two audits at the HFC, Carrollton, Texas facility. The audits were completed successfully. The majority of the safety and security qualifications of the HFC HFC-6000 safety control system were reviewed in great detail. These included:

Shin Kori Unit 1 nuclear power plant (South Korea) completed Performance Testing in January of 2010 and is expected to go into commission in November of 2010.  We anticipate finishing the same Performance Testing at Unit 2 in October of 2010.

In June 2009, HFC-6000 Triple Modular Redundant (TMR) and Dual Modular Redundant (DMR) architecture were approved by TUV as qualified IEC 61508 SIL3 safety system in the conceptual assessment phase of the certification. (A SIL3 safety system has a 99.9999% of availability.) Main assessment will be performed in the 1st quarter of 2010. HFC is expected to complete the certification by the second quarter of 2010. (The delay was mainly due to the NRC audits during the fourth quarter of 2009 and 1st quarter of 2010. No major system issues held up the certification process.)

Doosan HF Controls Corporation has received a contract valued at over $2 million to provide two (2) AAC/DG Control Systems. The ECS-1200 platform for non-safety and the HFC6000 for Safety Related Controls will be supplied on four (4) 1000 Mw Nuclear Power Plants to replace the existing legacy AAC Diesel Generator controls.  These plants are located in South Korea.

Doosan HF Controls Corporation has received TUV certification for the ECS 05B controller for TMR applications and the ECS 06 controller for safety related systems in a 2 out of 3 configuration where the safe state is the de-energized state.

The test results indicate the controllers are suitable for safety related applications up to SIL 1 in reference to IEC 61508, parts 1-7:1998-2000.

Please note the 24 hour Emergency contact number has changed.  The NEW number is 214-493-9500.  Please make note of this change.
