did? My God, I thought, maybe the fire is coming from the reactor room itself. I'd looked into the heart of the uranium atomic pile through a heavily leaded glass-inspection port and seen the indescribable unearthly radiance of it, a nightmarish coalescence of green and violet and blue, the new 'dreadful light' of mankind. What happened when this dreadful light ran wild? I didn't know, but I suspected I didn't want to be around when it happened.
I dressed slowly, not hurrying. My damaged hand didn't help me much but that wasn't why I took my time. Maybe the ship was on fire, maybe the nuclear power plant had gone out of kilter. But if Swanson's superbly trained crew couldn't cope with every emergency that could conceivably arise, then matters weren't going to be improved any by Carpenter running around in circles shouting: 'Where's the fire?
Three minutes after Hansen had gone I walked along to the control room and peered in: if I was going to be in the way, then this was as far as I was going to go. Dark, acrid smoke billowed past me and a voice — Swanson's — said sharply: 'Inside and close that door.'
I pulled the door to and looked around the control room. At least, I tried to. It wasn't easy. My eyes were already steaming as if someone had thrown a bag of pepper into them, and what little sight was left them didn't help me much. The room was filled with black evil-smelling smoke, denser by far and more throat-catching than the worst London fog. Visibility was no more than a few feet, but what little I could see showed me men still at their stations. Some were gasping, some were half choking, some were cursing softly, all had badly watering eyes, but there was no trace of panic.
'You'd have been better off on the other side of that door,' Swanson said dryly. 'Sorry to have barked at you, Doctor, but we want to limit the spread of the smoke as much as possible.'
'Where's the fire?'
'In the engine room.' Swanson could have been sitting on his front porch at home discussing the weather. 'Where in the engine room we don't know. It's pretty bad. At least, the smoke is. The extent of the fire we don't know, because we can't locate it. Engineer officer says it's impossible to see your hand in front of your face.'
'The engines,' I said. 'They've stopped. Has anything gone wrong — '
He rubbed his eyes with a handkerchief, spoke to a man who was pulling on a heavy rubber suit and a smoke mask, then turned back to me.
'We're not going to be vaporized, if that's what you mean.' I could have sworn he was smiling. 'The atomic pile can only fail safe no matter what happens. If anything goes wrong, the uranium rods slam down in very quick time indeed — a fraction under a thousandth of a second — stopping the whole reaction. In this case, though, we shut it off ourselves. The men in the maneuvering room could no longer see either the reactor dials or the governor for the control rods. No option but to shut it down. The engine-room crew have been forced to abandon the engine and maneuvering rooms and take shelter in the stern room.'
Well, that was something at least. We weren't going to be blown to pieces, ignobly vaporized on the altar of nuclear advancement: good old-fashioned suffocation, that was to be our lot. 'So what do we do?' I asked…
'What we should do is surface immediately. With fourteen feet of ice overhead, that's not easy. Excuse me, will you?'
He spoke to the now completely masked and suited man, who was carrying a small dialed box in his hands. They walked together past the navigator's chart desk and ice machine to the heavy door opening on the passage that led to the engine room over the top of the reactor compartment. They unlatched the door, pushed it open. A dense, blinding cloud of dark smoke rolled into the room as the masked man stepped quickly into the passageway and swung the door to behind him. Swanson clamped the door shut, walked, temporarily blinded, back to the control position, and fumbled down a roof microphone.
'Captain speaking.' His voice echoed emptily through the control center. 'The fire is located in the engine room. We do not know yet whether it is electrical, chemical, or fuel oil: the source of the fire has not been pinpointed.' Acting on the principle of being prepared for the worst, we are now testing for a radiation leak.' So that was what the masked man had been carrying, a Geiger counter. 'If that proves negative, we shall try for a steam leak, and if' that is negative, we shall carry out an intensive search to locate the fire. It will not be easy, as I'm told visibility is almost zero. We have already shut down all electrical circuits in the engine room, lighting included, to prevent an explosion in the event of atomized fuel being present in the atmosphere. We have closed the oxygen-intake valves and isolated the engine room from the air-cleaning system in the hope that the fire will consume all available oxygen and burn itself out.
'All smoking is prohibited until further notice. Heaters, fans, and all electrical circuits other than communication lines to be switched off — and that includes the juke box and the ice-cream machine. All lights to be switched off except those absolutely essential. All movement is to be restricted to a minimum. I shall keep you informed of any progress we may make.'
I became aware of someone standing by my side. It was Dr. Jolly, his normally jovial face puckered and woe- begone, the tears flowing down his face. Plaintively he said to me, 'This «is» a bit thick, old boy, what? I'm not sure that I'm so happy now about being rescued. And all those prohibitions — no smoking, no power to be used, no moving around — do those mean what I take them to mean?'
'I'm afraid they do indeed.' It was Swanson who answered Jolly's question for him. 'This, I'm afraid, is every nuclearsubmarine captain's nightmare come true — fire under the ice. At one blow we're not only reduced to the level of a conventional submarine — we're two stages worse. In the first place, a conventional submarine wouldn't be under the ice anyway. In the second place, it has huge banks of storage batteries, and even if it were beneath the ice, it would have sufficient reserve power to steam far enough south to get clear of the ice. Our reserve storage battery is so small that it wouldn't take us a fraction of the way.'
'Yes, yes,' Jolly nodded. 'But this no smoking, no moving — '
'That same very small battery, I'm afraid, is the only source left to us for power for the air-purifying machines, for lighting, ventilation, heating — I'm afraid the Dolphin is going to get very cold in a short time-so we have to curtail its expenditures of energy on those things. So no smoking, minimum movement — the less carbon dioxide breathed into 'the atmosphere, the better. But the real reason for conserving electric energy is that we need it to power the heaters, pumps and motors that have to be used to start up the reactor again. If that battery exhausts itself before we get the reactor going — well, I don't have to draw a diagram.'
'You're not very encouraging, are you, Commander?' Jolly complained.
'No, not very. I don't see any reason to be,' Swanson said dryly.
'I'll bet you'd trade in your pension for a nice open lead above us just now,' I said.
'I'd trade in the pension of every flag officer in the U. S. Navy,' he said matter-of-factly. 'If we could find a polynya I'd surface, open the engine-room hatch to let most of the contaminated air escape, start up our diesel — it takes its air direct from the engine room — and have the rest of the smoke sucked out in nothing flat. As it is, that diesel is about as much use to me as a grand piano.'
'And the compasses?' I asked.
'That's another interesting thought,' Swanson agreed. 'If the power out-put from our reserve battery falls below a certain level, our three Sperry gyrocompass systems and the N6A — that's the inertial-guidance machine — just go out of business. After that we're lost, completely. Our magnetic compass is quite useless in those latitudes — it just walks in circles.'
'So we would go round and round in circles, too,' Jolly said thoughtfully. 'Forever and ever under the jolly old ice cap, what? By Jove, Commander, I'm really beginning to wish we'd stayed up at Zebra.'
'We're not dead yet, Doctor… Yes, John?' This to Hansen, who had just come up.
'Sanders, sir. On the ice machine. Can he have a smoke mask? His eyes are watering pretty badly.'
'Give him anything you like in the ship,' Swanson said, 'just so long as he can keep his eyes clear to read that graph. And double the watch on the ice machine. If there's a lead up there only the size of a hair, I'm going for it. Immediate report if the ice thickness fails below, say, eight or nine feet.'
'Torpedoes?' Hansen asked. 'There hasn't been ice thin enough for that in three hours. And at the speed we're drifting, there won't be for three months. I'll go keep the watch myself. I'm not much good for anything else, this hand of mine being the way it is.'
'Thank you. First you might tell engineman Harrison to turn off the CO2 scrubber and monoxide burners. Must save every amp of power we have. Besides, it will do this pampered bunch of ours a world of good to sample a little of what the old-time submariners had to experience when they were forced to stay below maybe twenty hours at a time.'
'That's going to he pretty rough on our really sick men,' I said. 'Benson and Folsom in the sick bay, the
