Los Alamos lab prepares to reopen as fire threat eases

(Reuters) - The Los Alamos nuclear weapons laboratory has ended a state of emergency and was taking small steps on Saturday toward reopening as the threat from a record New Mexico wildfire subsided.

But highlighting the need for continued vigilance, a squirrel sparked a small blaze on lab property on Saturday when it touched a transformer. That fire, which measured about an acre, was quickly extinguished, the lab said in a statement.

Officials have yet to set any reopening date for Los Alamos, but with the risk to the laboratory and adjacent town mostly passed, lab director Charles McMillan said employees were slowly being prepared for reopening the lab.

"We've assessed the risk to the lab to be lower so we've changed the status based on that assessment," McMillan told a news conference.

The Las Conchas Fire consumed an additional 9,000 acres on Friday, and now stands at 113,734 acres, burning primarily toward the north, and further onto the western flank and into the Valles Caldera National Preserve.

A firefighting force of 1,600 people working to douse the flames has now managed to carve containment lines around 6 percent of the fire's perimeter on its eastern and southern flanks, keeping the blaze from invading the lab complex.

Now ranked as the largest wild-lands blaze ever in New Mexico, the fire surpasses the previous record set in 2003 by the 94,000-acre Dry Lakes Fire in the Gila National Forest.

By comparison, the largest blaze in Arizona, the Wallow Fire, has blackened well over 500,000 acres since it erupted May 29 of this year. It is still burning.

At one point earlier this week, the fire's edge was reported just 2 miles from a collection of about 20,000 metal drums containing plutonium-contaminated clothing and other waste stored on a corner of the 36-square-mile lab property.

Nuclear watchdog groups and some citizens had raised concerns about the fire possibly unleashing residual ground contamination left from decades of experimental explosions and waste disposal in the area.

FOCUS ON OTHER AREAS

The first employees to return to the Los Alamos lab, one of the nation's top nuclear arms production facilities, would be checking on the facilities, including air handling systems to be sure there was no clogging from the smoke, and bringing IT systems back on line, McMillan said.

A lab spokesman, Kevin Roark, said select employees would start returning on Saturday and that process would continue throughout the week.

McMillan said the status change at the lab would allow resources to be moved away from Los Alamos to focus on other areas, particularly in the north of the state where the fire continues to grow.

Officials have set no time for lifting evacuation orders for the town of Los Alamos, whose 10,000 residents fled earlier this week. Thick smoke lingered over the area.

On Thursday, the blaze had encroached on an Indian reservation to the north, the Santa Clara Pueblo, burning at least 6,000 acres of tribal land, including a number of sacred sites.

But the leading western edge of the blaze remained about 6 miles from the nearest populated areas of the pueblo on Friday, fire officials said at the time.

Firefighters on Saturday were conducting burnout operations to protect cultural and historical sites near the reservation, and archeologists were working with fire crews to minimize damage to sensitive areas, fire information officials said.

Thunderstorms and gusty winds expected on Saturday could spark new blazes or pose a hazard to firefighters, while downdrafts could help the fire spread, they added.

About 150 miles to the south, a separate wildfire caused by lightning blazed in and around the Mescalero Apache Reservation. By Friday morning, the Donaldson Complex Fire had burned some 90,000 acres, including several thousand acres on tribal land, but was 30 percent contained on Saturday, authorities said.

Nuclear reactor on North Carolina college campus leaking radiation since last Friday — Public not told because radioactivity was “compared to what someone might receive getting an x-ray”
July 7th, 2011 at 09:43 PM
http://enenews.com/nuclear-reactor-in-n ... g-an-x-ray
Minor water leak reported at NC State’s nuclear reactor, WRAL, July 7, 2011:

North Carolina State University officials said Thursday that there is a low-level water leak in the liner that surrounds the campus nuclear reactor, but that it poses no danger to the public.

University spokesman Keith Nichols described the leak, discovered Saturday, as the size of a pinhead and that it was leaking about 10 gallons per hour from the 15,000-gallon tank. [...]

Nichols said it would be considered a public threat if the reactor were leaking at 350 gallons per hour.

The university is in the process of repairing the leak [...]

NC State says nuclear reactor leak poses no threat, WTVD, July 07, 2011:

[Emphasis Added]
[...] The reactor is housed in the Burlington Nuclear Engineering Laboratory. The building is located at 2500 Katharine Stinson Drive. [...]

NC State said the leak was suspected on Friday and confirmed on Saturday. It said the public was not informed sooner because of the low level of danger. The amount of radioactivity was compared to what someone might receive getting an x-ray.

The school says the leak is so small that special equipment is required to detect its location in the reactor’s lining. The company that can do that will not be in Raleigh until next week. In the meantime, the leak is being closely monitored. The reactor has been shut down since the leak was discovered.

Soldiers watch over levees, Omaha World Herald, July 10, 2011:

The military helicopter’s black shadow dances on an engorged Missouri River as the aircraft slowly loops the flood-encircled Fort Calhoun Nuclear Station — the same left-leaning turns the pilot navigated two days prior.

Warrant Officer Boe Searight, 32, with the Nebraska Air National Guard [...] and his colleague Chief Warrant Officer 2 Eric Schriner also are looking for new signs of trouble for the flooded plant.

“Keep daily eyes on it and see if anything changes,” says Schriner, 31. [...]

Fire at nuclear testing area 65 miles NW of Las Vegas — Feds checking for radiation
July 11th, 2011 at 04:32 PM
http://enenews.com/fire-nuclear-testing ... -radiation
A wildfire at the government’s former nuclear testing area in southern Nevada poses no threat of kicking up radiation, federal officials said Saturday. [...]

National Nuclear Security Administration spokeswoman Kelly Snyder said the lightning-caused blaze was not burning near any site where 100 above-ground tests left radiation in the soil. [...]

But Snyder said ground and air crews were still trying to contain the blaze Saturday and there was no estimated containment time. [...]

“This is an active fire. We have a variety of aircraft dropping water on the fire,” she said.
Las Vegas Review Journal, July 9, 2011:
[...] Lightning sparked two fires Tuesday within the Nevada National Security Site, the former nuclear test site 65 miles northwest of Las Vegas. [...]

One of the fires is “several miles” from the location of an above-ground test, a safe distance according to Dante Pistone, a spokesman at the test site’s operations center [...]

“Emergency declared” at New Jersey nuke plant after reactor coolant leak — “Leakage outside containment”
July 15th, 2011 at 10:41 AM
http://enenews.com/emergency-declared-n ... ontainment

Event Notification Report for July 15, 2011, NRC, July 15, 2011:
Event Number: 47052
Facility: SALEM
Region: 1 State: NJ
Event Date: 07/14/2011
Event Time: 20:53 [EDT]
Emergency Class: UNUSUAL EVENT
10 CFR Section: 50.72(a) (1) (i) – EMERGENCY DECLARED [...]

UNUSUAL EVENT DECLARED BASED ON REACTOR COOLANT LEAK GREATER THAN 10 GPM

“At 2053 on July 14, 2011 Salem unit 2 declared an Unusual Event due to reactor coolant system leakage greater than 10 gallons per minute. While performing a monthly Emergency Core Cooling System vent of the high head safety injection piping a motor operated valve was opened and a leak developed on the high head piping greater than 10 gallons per minute. The leak rate was approximately 11-15 gallon per minute. The leak was terminated when the motor operated valve was closed. The time of the leak was about 6 minutes.”

At this time the leak is believed to be from a crack on the Boron Injection Tank (BIT) relief valve line which is connected to the high head piping. A total of approximately 90 gallon of reactor coolant leaked into the BIT room. The licensee has declared the high head safety injection inoperable and is proceeding to shutdown under Tech Spec 3.0.3. [...]

* * * UPDATE FROM KARL HANPHO TO VINCE KLCO ON 7/15/11 AT 0025 EDT* * *

“Salem Unit 2 declared an Unusual Event due to Reactor Coolant System (RCS) leakage being greater than 10 gpm and pressurizer level decreasing. Leakage was estimated to be approximately 15 gpm. [...] Salem Unit 2 began the Technical Specification shutdown [...]

“In addition since the leakage from the weld on the high head charging/safety injection piping exceeded the analyzed limit for ESF leakage outside containment, this event is also being reported in accordance with 10CFR50.72(b)(3)(v) and RAL 11.2.2.b as a condition that prevents the ability to mitigate the consequences of an accident.

“Salem unit 2 is currently at 27% and reducing power.” [...]

* * * UPDATE FROM KARL HANPHO TO CHARLES TEAL ON 7/15/11 AT 0345 EDT* * *

Salem Unit 2 has exited the Unusual Event as of 0339 EDT. The criteria for exit was the leakage rate was below the 10 gpm rate. The plant is in Mode 3 and is preparing to cooldown.

CBS: Nuclear workers “terrified to come forward” — Whistleblower won’t appear on TV fearing retaliation by NRC (VIDEO)
July 20th, 2011 at 01:49 PM
http://enenews.com/cbs-nuclear-workers- ... -nrc-video

A crying Janice Overall told CBS News her husband, Curtis, “paid the ultimate price.” [...] an award-winning employee who helped run Watts Bar’s unique ice containment system, designed to prevent a nuclear meltdown.

But in 1995, after Overall discovered what he believed were problems with the system on the eve of Watts Bar’s long-delayed startup, he got harassed with threatening notes, and even a fake bomb discovered in the back of his pickup. Battling a bad heart and deep depression, Overall died in 2007 at the age of 56, without any proof of who had harassed him. [...]

“People are terrified to come forward at TVA,” [attorney Lynne Bernabei] asserts. “It’s just like back in 1985. Nothing has changed. They’re terrified to come forward because they know that they will not get employment at TVA.” [...]

Says Bernabei, “The whole regulatory system is based on self-reporting by the utility employees. If those employees are scared of coming forward, you’re not going to get the safety problems reported, and you’re gonna have a plant that is not safe.”

CBS News spoke with one whistleblower, Gail Richards, who said she was too afraid to appear on-camera for “fear of further risk of retaliation for me and my family by the TVA and NRC.”
CBS also discussed a 1986 report documenting what investigators called “widespread intimidation, harassment and discrimination by TVA management,” along with “widespread mistrust.”

Cooling system for reactors and spent fuel pools stopped working three times over 16-day period at Alabama nuke plant
July 28th, 2011 at 05:20 PM
http://enenews.com/cooling-system-react ... nuke-plant

After tornadoes, TVA will replace emergency sirens, TimesDaily by Eric Fleischauer, July 28, 2011:
A Tennessee Valley Authority official said Wednesday the authority plans to correct a problem that left only 12 of Browns Ferry Nuclear Plant’s required 100 emergency sirens working after the April 27 tornadoes. [...]

The same power loss that left 88 sirens useless also caused problems at the nuclear plant.

All three reactors shut down automatically April 27. Because of the distraction of reactor personnel, according to a report TVA filed this month with the Nuclear Regulatory Commission, water levels dropped in the Unit 1 reactor when the water boiled off faster than it was replaced. The cooling systems that control the temperature of the reactors and spent fuel rods stopped working for 47 minutes on April 28, 57 minutes on May 2 and 40 minutes on May 12. [...]
