“They’re going to make decisions on an acre-by-acre basis as to what’s going to happen to these facilities,” she said. “The area around Chernobyl is now a nature park. When you move 100,000 people out of an area, nature does pretty well.”
Many nuclear plants have a myriad of tunnels and buildings underground, and many of those tunnels have an exterior layer of concrete that must be protected from water. Plants, like Seabrook, often have waterproof membranes to protect the concrete’s integrity and extensive efforts to drain ground water.
The tunnel and other areas where water seepage was found are part of a safety system used to help cool the reactor when it is being shut down. In addition to the concrete tunnel problem, NextEra found corroded steel supports, piping, and anchor bolts in other areas they inspected but none have degraded concrete or in any way endanger the plant, said NextEra.
Tokyo Electric Power Co. (9501.TO) said Tuesday that the sound of an explosion was heard at the Fukushima Daiichi nuclear complex, but radiation levels haven't increased and no injuries were reported, Kyodo News reported.
TOKYO, May 31 - RIA Novosti, Xenia Naka. While cleaning up the territory around the fourth unit of Japanese nuclear power plant "Fukushima-1, an explosion occurred, Kyodo news agency reported with reference to the plant operator TEPCO.

Oxygen cylinder bursts near No. 4 reactor
An oxygen cylinder has burst at the Fukushima Daiichi nuclear plant. But the plant operator says the blast caused no damage to the plant's facilities, and no injuries.
At around 2:30 PM on Tuesday, workers reported hearing a loud noise like that of an explosion at the south side of the plant's No. 4 reactor.
The Tokyo Electric Power Company says unmanned heavy machinery removing debris at the site damaged the cylinder, causing it to burst.

Oil has been found leaking into the sea near the crisis-hit Fukushima nuclear power plant, possibly from nearby oil tanks that may have been damaged in the March earthquake and tsunami, the plant operator said Tuesday, adding that it will set up oil fences to prevent the liquid from spreading into the Pacific Ocean.
The oil slick was found at 8 a.m. by Tokyo Electric Power Co workers who were patrolling the premises of the plant on the Pacific coast, and is believed to be spreading at a 200-300 meter range inside breakwaters.
Tokyo Electric suspects that the oil may have leaked from tanks located near the water intake for the Nos. 5 and 6 reactors or pipes that deliver the oil, because the March 11 disaster took place when a tanker was supplying oil. One of the tanks was moved from its original location because of the tsunami.
Lights, camera, action: as of Tuesday morning Fukushima Daiichi will literally be in the spotlight. Tokyo Electric Power Co. A screen shot of the live webcast of Fukushima Daiichi to be launched by Tepco on June 1. Tokyo Electric Power Co. said Monday it will start a live webcast of the nuclear power plant at the center of Japan’s two-month drama. The video will be shot from 250 meters northwest of Unit No. 1 and will show images of Units Nos. 1-3 in real time, the most heavily damaged of the plant’s six reactors, according to Tepco.
Tepco’s Corporate Ratings Cut to Junk by S&P
By Ryan Woo - May 30, 2011 7:55 AM ET
Tokyo Electric Power Co.’s corporate credit ratings were lowered to junk status by Standard & Poor’s Ratings Services, which cited an increasing likelihood that banks may restructure some of the utility’s debts.
Shares of the utility have fallen 85 percent since March 10. Tepco rose 1.6 percent to close at 326 yen today, before the S&P downgrade.
“Tepco’s worsening financial position increases the likelihood its lender banks could restructure its borrowings,” S&P said. “Any waiver of loans or distressed restructuring, such as a lowering of interest rates on existing loans, constitutes a form of default and would trigger a lowering of the corporate credit ratings on Tepco to SD -- Selective Default. www.bloomberg.com...
Tokyo, May. 31 (BNA) -- Water levels in the basement of the No. 1 reactor building at the stricken Fukushima No. 1 nuclear power plant increased dramatically on May 29 and 30, raising fears of radioactive water leaking from the site.
The plant's operator, Tokyo Electric Power Co. (TEPCO), said the water level rose 19.8 centimeters over the 24 hours to 7 a.m. on May 30, 18 times the increase over the previous 24 hours.
The rising water level, apparently caused by rain flowing into the basement, is the latest headache for workers trying to contain the crisis at the plant. With the typhoon and rainy seasons already drenching Japan, TEPCO had already expressed concern that a deluge could result in leaks.
TEPCO spokesman Junichi Matsumoto said before the latest data was announced: "The roofs of the No. 1, No. 3 and No. 4 reactor buildings have collapsed, so it is unavoidable that rain will get into those facilities."
