“…In previous work, Idaho National Laboratory (INL) evaluated the suitability of several TES technologies for coupling with A-NPPs, based on qualitative and merit indicators. Two-tank molten-salt, solid-media, and latent-heat TES systems were deemed well suited for coupling with a wide range of A-NPPs featuring different reactor sizes and temperatures [1] [2]. These findings, coupled with previous work in the field [3], provide the starting point for a more in-depth analysis.…”

This report discusses the different options for coupling thermal energy storage (TES) systems to advanced nuclear power plants (A-NPPs) in order to enable flexible and hybrid plant operation. An advanced light-water reactor (A-LWR), a high-temperature gas-cooled reactor (HTGR) and a liquid-metal fast reactor (LMFR) were selected as the initial use cases for demonstrating a thermally balanced energy storage coupling design for thermal power extraction. v

“…It is notable that feedheat/feedwater storage has been largely overlooked in much of the recent work and the focus has instead been upon extracting heat from live steam, usually combined with storage in phase-change materials (PCMs). As Saeed et al 34 note, however, transferring heat in and out of PCMs is less straightforward than for sensible heat media, essentially because the heat-exchange network has to permeate all of the storage vessel. Storage systems coupled with the feedheat train integrate easily with sensible heat storage and allow heat to be transferred in an exergetically efficient fashion.…”

The paper provides thermodynamic analysis of an energy storage concept in which thermal stores are coupled with the feedwater heating train of nuclear-powered steam plant. This allows the electrical output of the plant to be flexed whilst maintaining constant reactor power, thereby providing the equivalent of an electricity storage system and facilitating the adoption of a load-following role for nuclear plant. The concept falls under the umbrella of ‘generation-integrated energy storage’, which exploits existing hardware required for generation to reduce storage costs, and benefits also from fewer energy transformations when compared to ‘electricity-in-electricity-out’ forms of storage. This means that a high (effective) round-trip efficiency can be achieved at low cost. An important feature of the proposed system is that the turbine bleed flows (at their various pressures and temperatures) automatically provide good thermal matching with the feedwater temperature profile, so that heat can ultimately be transferred to and from sensible-heat thermal-storage media with high exergetic efficiency. Various options are discussed for the thermal stores, including pressurised water tanks, thermal oils and packed beds. The analysis also includes consideration of the off-design behaviour of cycle components.

This publication details newly created energy storage and reactor models developed within the HYBRID modeling repository as part of the Department of Energy (DOE) Office of Nuclear Energy Integrated Energy Systems (IES) program, led by Idaho National Laboratory (INL).The model development included creating dynamic systems-level models of a pebble-bed high-temperature gas-cooled reactor (HTGR), a sodium fast reactor (SFR), compressed air energy storage (CAES), liquid air energy storage (LAES) and Modelica standard library (MSL)-based two-tank sensible heat storage (SHS) in the IES-based HYBRID repository. These models were developed using the latest publicly available data and incorporating the possibility of control strategy inclusion for use with the existing IES modeling, analysis, and optimization toolset. Simulations showcase the capability of each technology to flexibly operate in ways consistent with IES operation expectations.When these models are available, they can be utilized within different integrated energy park concepts to understand optimal system operation, control, and dispatching. Moreover, given the generic nature of the models, industrial partner technologies can be quickly added to the repository by using the existing models as a basis. Additional dynamic models for thermal energy storage (TES) concepts can be developed and added to the HYBRID repository as needed. Also detailed in this report are future development goals for the HYBRID repository, including adding suites of steady-state models, economic costing information, and reduced-order models (ROMs).
