Reactor was developed by Tim Skelly, who was also responsible for Star Castle. It was the first arcade game to credit the developer on the game's title screen.

Usage examples of "reactor".

Murphy walked aft to look into the maneuvering room to see how the Engineering Officer of the Watch was handling the frantic actions required during a reactor scram.

The deck began to tremble as the huge twin steam propulsion turbines aft came up to full revolutions, blasting the Tampa through the water at one hundred percent reactor power.

Jesus, Murphy thought, not just a reactor scram but a fucking steam leak--a ruptured main steam line had enough energy to roast everyone in the aft compartment.

The nukes back aft must have gotten the reactor restarted, he decided.

Access fore and aft is through a shielded tunnel, since anyone inside the compartment when the reactor is critical would be dead within a minute from the intense radiation.

I understood, would consist of engineered microbes, their genetic material spliced together from bacteria discovered inside rocks in the dry valleys of Antarctica, from anaerobes capable of surviving in the outflow pipes of nuclear reactors, from unicells recovered from the icy sludge at the bottom of the Barents Sea.

The new Russian reactor coolant pumps on the AKULA class made that sound.

Worst leaks look to be primary coolant, and the radiation level in the reactor compartment is climbing.

And relay the word to maneuvering: group scram the reactor, secure all reactor main coolant pumps, engage emergency cooling, shut main steam valves one and two and secure steam to the engine room.

In the center of the coolant system was a reactor core with a pistol-grip lever protruding from it that moved the control rods.

Delaney would need power to restart the reactor, especially for the power-hungry reactor main coolant pumps.

The reactor operator, an aggressive first-class petty officer named Manderson, acknowledged and flipped each reactor main coolant pump T-switch on the lower reactor control panel to the slow speed position, then pulled each switch upward.

Then the liquid reactor coolant sprayed and flooded the compartment as the number-two reactor vessel flew off its foundation and careened to the aft bulkhead, where it punctured the titanium wall.

With less than minutes left on the battery in this reducedload status, the running of the reactor main coolant pumps to get flow through the core would exhaust the battery in three minutes or less.

The leak had dumped one coolant loop of highly radioactive water to the reactor compartment bilges.
