Operation and Control of the INL Thermal Energy Delivery System (TEDS)
Nuclear Renewable Hybrid Energy Systems (NR-HES) is an area of current research interest as wind and solar grid penetrations continue to increase. The goal of these systems is to operate at ~100% capacity and store excess energy, when available, for later use. To store this excess energy some form of storage is needed. Sensible heat Thermal Energy Storage (TES) systems have been shown to be an effective thermal load management strategy allowing nuclear reactor systems to operate at effectively 100% full power while storing excess thermal energy for recovery at a later time. Thermal storage is modeled extensively around the world. However, little in the way of experimentation is being conducted. Experimentation is needed to verify the dynamics and control of TES systems. In an effort to complement the modeling and simulation efforts on nuclear-renewable hybrid energy systems, Idaho National Laboratory INL is in the process of designing a Thermal Energy Delivery System (TEDS). The system will provide a means of distributing thermal energy to and from various co-located systems located in the INL Dynamic Energy Transport and Integration Laboratory (DETAIL). DETAIL will include a high-pressure high-temperature water flow loop simulating a Pressurized Water Reactor (PWR), a 25 kWe High-Temperature Steam Electrolysis (HTSE) unit (first potential heat user/customer) and a packed-bed Thermal Energy Storage (TES) system. The thermal energy transfer from TEDS can be used in a flexible, dynamic manner incorporating charging and discharging cycles from the TES system, to support test/demonstration operations for nuclear-renewable hybrid energy systems (N-R HES) applications. TEDS is being designed, such that the loop can be expanded to supply thermal energy to additional systems integrated into the DETAIL testbed over time with minimal disruptions to DETAIL testbed operations. This paper discusses the design, operation, control strategies, sensor placement, and physical layout of TEDS. Additionally, the DETAIL and TEDS demonstration units will provide data for the validation and verification of models developed worldwide thus, allowing a better understanding of NR-HES systems.
