You will observe: that the terminals of the power transformer secondary coil which develops 10 volts are connected to the filaments of the oscillator tubes; that the terminals of the other secondary coil which develops 10 volts are connected with the filaments of the rectifier tubes; that the terminals of the third secondary coil which develops 550 volts are connected with the plates of the rectifier tubes; that the pair of filter condensers are connected in parallel and these are connected to the mid-taps of the two filament secondary coils; that the reactance coil and the third filter condenser are connected together in series and these are shunted across the filter condensers, which are in parallel; and, finally, a lead connects the mid-tap of the 550-volt secondary coil of the power transformer with the connection between the reactor and the third filter condenser.
The Polaris unit quickly checked out Kit's ship as qualified for the race, and then turned, fascinated, to the tangle of pipes, cables, and mechanical gear of the reactor unit and cooling pumps. Tom and Roger were unable to figure out exactly what changes Kit had made, but Astro gazed at the new machinery fondly, almost rapturously.
When the trucks had labored to the top of a ridge, the spaceport installations came into view all at once: Barbed-wire fences, low, olive-drab gate buildings, guidance tower, the magnesium dome of a powerhouse reactor, repair and maintenance shops, personnel-housing area carefully shielded against radiation by a huge stellene bubble, sealed and air-conditioned, with double-doored entrances and exits.
So I have to use them outside the reactor area, on fabrication and assembly work. And I have to hire through the union, and that's handled on a membership seniority basis, so I have to take what's thrown at me. That's why I was careful to get that clause I was quoting to Sid written into my contract. "Now, here's what's going to happen.
If he survived that, it's his bad luck," Melroy said grimly. "Last night, while Fred Hausinger was pulling the fissionables and radioactives out of the Number One breeder, he found a big nugget of Pu-239, about one-quarter CM. I don't know what was done with it, but I do know that Crandall had the maintenance gang repack that reactor, to keep my people from working on it.
While Tom and Roger made decisions quickly and decisively, Astro, on the other hand, patiently listened to all the tearful stories and sympathized with the applicants when they were unable to tear down a small reactor unit and rebuild it blindfolded.
We use that heat to turn a chemical called methane into its component parts. Methane is known as marsh gas, Foster. I wouldn't expect a Planeteer to know that. It is composed of carbon and hydrogen. When we pump it into the heat coils of the reactor, it breaks down and creates a gas that burns and drives us through space. But that isn't all it does."
That had been three months ago. Melroy and his people had moved in, been assigned sections of a couple of machine shops, set up an assembly shop and a set of plyboard-partitioned offices in a vacant warehouse just outside the reactor area, and tried to start work, only to run into the almost interminable procedural disputes and jurisdictional wranglings of the sort which he privately labeled "bureau bunk". It was only now that he was ready to begin work on the reactors.
"I have some work to finish, so I'll leave you now. Good luck, Steve." She shook hands with the young captain and left. Walters turned back to Strong. "Well, now that's settled, tell me, what do you think of the race tomorrow, Steve?" "If Kit Barnard gets that reactor of his functioning properly, he'll run away from the other two." "I don't know," mused Walters.
Always generalities like that; never anything specific." "I know all that." The boy seemed offended, as though somebody were explaining that his mother hadn't really found him out in the rose garden. "But they talked about it to some of their friends, and it seems that other mediums are saying the same thing. Father, do you remember when the Haval Valley reactor blew up?
