2022, Progress in Nuclear EnergyCitation Excerpt :The SNTP program's Phase I goal, under management of the SDI office, was to design a 2nd stage NTP engine for an ICBM interceptor (Haslett, 1995). The PBR concept involves containing a pile of fuel particles within two cylindrical containers called frits, with propellant fluid pumped through the particle bed to gain heat and produce thrust upon exiting the rocket (Ludewig et al., 1996). Timber Wind's development approach was aggressive, focused both on a design study of the engine's requirements (∼2973 K exit temperature, high power density) and experimental testing within a short timeframe.

2021, International Journal of Heat and Mass TransferCitation Excerpt :To expand it more, there is great interest in both academy and industry to investigate the use of particulate beds of metal hydrides for applications such as heat pumps [13,14]. Particle bed reactors are being designed for space nuclear applications [15]. As mentioned, thermal management in most of these applications is critical in the design process.
