Digital Control Upgrades

Home › Energy

Our San Francisco Office (SFO) is the Center of Excellence for Digital Control Systems Upgrade Consulting. Our comprehensive capabilities include Planning, Implementation, and Installation as well as experienced in completing successful upgrades, on time and on budget.

Planning

Using our Control Systems Upgrade Advisor (Advisor) software tool set, we'll prioritize your I&C systems, enabling plant owners to establish a rational, defensible, long-term risk versus benefit assessment process. The process combines generic and plant-specific considerations derived from Standard Review Plan, INPO AP-913, expert panel input and pilot implementation lessons at several plants.

We'll assist you in developing your overall Strategic Plan followed by the Conceptual Design and Functional Requirements Specification, which includes the I/O list, for each system. Since we're a participant in the EPRI Diversity and Defense in-Depth (D3) Working Group, we are up to speed on acceptable licensing methods to address digital Common Cause Failures (digital CCFs). We work with you on the development of control system hardware and HMI standards to help insure that multiple, incremental upgrade projects avoid proliferation of one-off computing equipment and HMI but fulfill D3 requirements. This standardization is critical to managing downstream maintenance and training costs and ensuring a simple and consistent environment for plant operators.

Altran Solutions will develop guidelines for the planning and implementation of DCS upgrade projects as well as validation, training and assistance with the implementation of reviewed and revised design procedures. We'll also develop the total job cost.

Implementation

Our 10CFR50 Appendix B QA program enables us to develop and implement Design Change Packages (DCPs) and includes assistance with preparation of 10CFR50.59 safety evaluations. We've integrated our QA program with plant procedures so we can produce DCP deliverables in plant-specific formats.

Altran Solutions has personnel whose expertise includes System Development Life Cycle (SDLC) processes related to design and implementation of DCS projects as well as V&V oversight, FAT/SAT and post-installation test procedures and Configuration Management plans.

We offer a complete range of independent review services as well training on development and implementation of design procedures. We also offer a global training program on digital control systems in nuclear plant applications. And our design and implementation generally includes consideration for spare parts, calibration, hot-swap or planned off-line maintenance, and the impact of maintenance intervals on system operability.

Installation

We offer post-installation testing support for digital control systems and component upgrade projects and we complete the process by offering comprehensive project close-out services that include compilation and review of documents, drawings, databases, etc., that are part of the client-specific design change processes.
