    The problem set associated with the heat transfer from the fuel stick to the coolant gas in the HTGR is illustrated in Fig. 1 where the radial temperature drop is traced from the fuel stick centerline to the coolant gas. In detail, in the HTGR the coated particle fuel is embedded in a carbon matrix in the form of cylindrical fuel sticks. Tristructural isotropic (TRISO) coated particle fuel is a robust, microencapsulated fuel form developed originally for use in high-temperature gas-cooled reactors (HTGRs). The particles consist of a spherical fissile kernel surrounded by several layers of pyrocarbon and a silicon carbide (SiC) layer.

    In this case the old idea is the “high temperature gas reactor” or HTGR, that then was proposed in a modular version, known as the MHTGR. The PBMR is a variant of the HTGR.

Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.

An overview of HTGR fuel recycle is presented, with emphasis placed on reprocessing and fuel kernel refabrication. Overall recycle operations include (1) shipment and storage, (2) reprocessing, (3) refabrication, (4) waste handling, and (5) accountability and safeguards. The Thorium Utilization National Program Plan for HTGR Fuel Recycle Development includes the demonstration, on a production scale, of reprocessing and refabrication processes in an HTGR Recycle Demonstration Facility (HRDF).

A summary plan is introduced for completing conceptual definition of an HTGR Recycle Reference Facility (HRRF). The plan describes a generic project management concept, often referred to as. Summary report An availability analysis of reprocessing systems in a high-temperature gas-cooled reactor (HTGR) fuel recycle facility was completed.

This report summarizes work done to date to define and determine reprocessing system availability for a previously planned HTGR recycle reference facility (HRRF).

@article{osti_, title = {Irradiation performance of HTGR recycle fissile fuel}, author = {Homan, F. and Long, Jr., E. L.}, abstractNote = {The irradiation performance of candidate HTGR recycle fissile fuel under accelerated testing conditions is reviewed.

Failure modes for coated-particle fuels are described, and the performance of candidate recycle fissile fuels is discussed in. However, only about 40% of the elements in the recycle mode of operation contain recycle fuel, the remaining 60% contain fresh make-up fuel.

The net difference in fabrication cost is only mill/kWh between the two modes of operation. Shipping and reprocessing R.C. Dahlberg et al., HTGR fuel and fuel cycle 71 Table 6.

For 8% enriched UO 2 fuel, mixing BPPs containing B 4 C with radius of 75 μm through the fuel zone of a standard HTGR fuel pebble with outer radius of 3 cm, the reactivity swing is 2% at a k ∞ of This means the burnable poison occupies a vol less than that of the fuel pebble (FVR = 60,).

Highlights Fuel cycle analyses of LWR–ARR, LWR–HTGR–ARR, and HTGR recycling scenarios. A 30% reduction in the natural uranium consumption over the once-through cycle.

A great reduction of TRU waste generation over the once-through cycle. The electricity generation costs of 39, 35 and 26 USD/MW h(e) for three scenarios. Economic benefits of an HTGR owing to its high fuel burnup.

The actual spent fuel mass represents only 4% of the fuel element mass unloaded from the HTGR (compared with nearly 70% for a spent LWR fuel element). For an equivalent actinide loss in the waste stream, this difference requires substantially better actinide recovery performance than can be obtained with current head-end processes.

Japan’s HTGR program is focused on the Atomic Energy Agency’s high-temperature test reactor (HTTR) located in Oarai, Ibaraki prefecture. New types of nuclear reactors are developed in stages, and the HTTR, with a thermal output of 30, kilowatts, is the first stage in this process.
