Pressure-fed cycle NERVA ?

[Michel Van]

Original nuclear rocket engine like NERVA had Turbopump-fed cycle
I wonder if someone consider also Pressure-fed cycle or even test it ?

I only know one nuclear rocket engine design with Pressure-fed cycle
The nuclear salt-water rocket, Wat use water bearing dissolved salts of U235 as fuel, stored in long tubes tanks made out of boron.
