If the top hose gets hot that means that the thermostat HAS opened. Thermostats remain closed until the engine warms up then the thermostat only opens enough to keep the temperature at about the set-point temperature of the thermostat. Just repair the radiator and enjoy the vehicle.

Is it safe to run vehicle with a bad thermostat?
A "bad" thermostat is probably one that is sticking. If it sticks open, the engine coolant will circulate through the radiator at all tiimes, making the car hard to warm up in the winter, and slightly less efficient according to the laws of heat engines. If the thermostat is stuck closed, the coolant will never circulate through the radiator, which could cause the engine to be damaged by overheating.

Your thermostat is stuck closed. you will need to replace it. The thermostat controls the circulation through the radiator - when the engine heats up the thermostat is meant to switch circulation from just-engine to engine+radiator. Sounds like this isn't happening.
