OPG is exploring the use of EPC contracts for Nuclear Plant Design Modifications.   Although OPG has used EPC outside of the nuclear island, this new initiative will begin to use EPC inside the plant, including upgrades to existing stations and mid-life refurbishment ofDarlington.   Benchmarking has shown that apart from new build, nuclear utilities rarely use this method inside the plant so OPG is using a step-by-step approach starting with projects with low complexity and low plant impact.

The expected benefits are reduced interfaces and a simplified accountability model leading to schedule and cost improvements and lower rework.  Design packages that incorporate construction input before issue will be a significant improvement.

OPG’s early challenges in moving to EPC include clearly defining roles, responsibilities and interfaces between the vendors and OPG, and modifying governance to match the new model.   OPG intends to oversee the work while holding the vendor accountable for needs skill development on both sides.

Vendors are expected to establish an engaged organization with complete knowledge of plant conditions, processes and streamlined methods to gain operations input. Vendors are also expected to identify and fix any quality issues before the modifications are commissioned and to have an in-house corrective action program to continuously improve.     Vendors’ early challenges include presenting one face to OPG rather than a collection of joint venture partners.

Chief Nuclear Engineer Mark Elliott will describe OPG’s plans and early feedback on this exciting new initiative.
