(PDF) Concept of an Accelerator-Driven Advanced Nuclear Energy System
This is that chinese ASDR concept using solid micrograins as a pumpable solid coolant that doubles as the neutron spallation target for the particle accelerator. Apparently there were concerns over the thermal shock from a beam trip event requiring a more robust neutron target.

Nuclear Propulsion Along Inland Waterways
This is actually an argument in favor of mobile thermal batteries with their heat engines, and a recharging infrastructure (which preferably uses small nuclear heat sources). Fireless steam locomotives are still in use in select industries that use a large steam vessel recharged by an external steam source, but newer thermal batteries could improve on things.

The Nuclear Power Dilemma (2018) | Union of Concerned Scientists
So a major environmental group is still opposed to new nuclear, but now officially concedes existing nuclear is needed for a transition to a renewable energy future. Practical choice of the lesser of two evils (nukes vs climate change itself)

On the Use of a Pulsed Nuclear Thermal Rocket for Interplanetary Travel | 52nd AIAA/SAE/ASEE Joint Propulsion Conference
Fission pulses do neutron heating of hydrogen propellant to plasma conditions, but you need to liquid metal cool the fuel. Neat result is propellant can get hotter than the fuel due to neutron flux. Though a NTER strikes me as easier to implement...

Turbo Rocket 8Jul18.pptx - Google Drive
Bringing back the NTTR for another round, this time it looks like it's taking the immense heatsink advantage of LH2 to run a fan/compressor for a SERJ and the turbopumps for an otherwise conventional rocket engine pack. Sorta conceptually similar to RocketLabs doing an end-run by using an electric motor to boost a conventional rocket motor that would have been limited to pressure fed or gas-generator.

Milestone for new LEU research reactor fuel
I think the bigger takeaway may be the fuel design, moving from a single hex rod to a series of tightly packed plates, which is intended for reactor uprate projects using existing fuel assembly dimensions.

Mobile Energy Depot Feasibility Study - Summary Report
So the US Army studied a mobile energy depot concept, basically a portable nuclear reactor and a synthetic fuel production facility, to cut the logistical trail of a military on the move. Emphasis on a hydrogen fuel cell logistics train with hydrogen, run via a liquid metal cooled reactor (derivative of the ANP nuclear aircraft engine reactors).

Quarks fuse to release energy | Nature
Quark fusion pretty powerful, but needs heavy baryons and goes poof quick so not practical on it's own. But, with a 138MeV bandgap, could this be a used for a quark laser (similar to a nucleon laser)?
