Tropical Storm "Cristobal" to become hurricane by Wednesday

Tropical Storm “Cristobal”, the third tropical storm of the 2014 Atlantic hurricane season, formed from System 96L near southeastern Bahamas during Sunday morning, August 24, 2014. This system is expected to become a hurricane on Wednesday. ​Tropical Storm Warnings were issued for Southeastern Bahamas, Including the Acklins, Crooked Island, Long Cay, the Inaguas, Mayaguana, the Ragged Islands, as well as the Turks and Caicos Islands, Central Bahamas, Including Cat Island, The Exumas, Long Island, Rum Cay, and San Salvador.At 15:00 UTC today Cristobal was centered about 120 miles (195 km) east-northeast of San Salvador Island, Bahamas, and 715 miles (1 150 km) southwest of Bermuda moving toward the north-northeast near 5 mph (7… »

Moderately strong solar flare reaching M3.9 erupted from Region 2146

After M2.0 at 15:11 UTC today Active Region 2146 erupted with another M-class solar flare. This latest event started at 20:06, peaked at 20:21 as M3.9 solar flare and ended at 20:29 UTC.As with previous event the majority of plasma cloud appears to be directed away from our planet.NOAA SWPC forecasters estimate 50% chance for M-class, and 10% chance for X-class solar flare in next two days.SunspotsThere are currently 8 numbered sunspot regions on the disk. Region 2151 developed a small trailer spot, but remained largely unchanged since the M5.9 flare yesterday. Other regions on the visible disk were either stable or in decay.Sunspots on August 25, 2014. Image credit: NASA SDO/HMI2141 – Alpha2142 – Beta2143 – Beta2146 – Beta2148 – Beta2149 – Bet… »

NRA Volcano Review Of Nuclear Safety Abruptly Exposes Reality

NRA began their review of nuclear safety related to volcano’s this week. This would be considered a good thing for a country full of volcanoes.
The first meeting exposed some inconvenient problems with the notion of nuclear power plants and volcanoes peacefully co-existing.
“The Nuclear Regulation Authority, or NRA, guidelines require nuclear power plant operators to take specific actions if volcanic activity could affect operations. The actions include taking nuclear fuel out of the facilities.”
TEPCO has been trying to remove the spent fuel out of unit 4 for going on a year before they will have completed the task. The reactor was empty of fuel at the time of the disaster. Fresh spent nuclear fuel is usually considered safe to remove from the spent fuel pool after about 5 years. So removing fuel from the reactor and into a cask to actually remove it from a nuclear plant is not a quick …

Moderately strong M2.0 solar flare erupted from Region 2146

Moderately strong M2.0 solar flare erupted on August 25, 2014, from Active Region 2146 (beta). The event started at 14:46, peaked at 15:11 and ended at 15:31 UTC.A Type II (707 km/s), IV and Tenflare (170 sfu) radio emissions were associated with this event. Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong Coronal Mass Ejections (CME) and solar radiation storms.It is possible that part of the plasma cloud is directed toward our planet. More information will be available after the analysis.NOAA SWPC forecasters estimate 50% chance for M-class, and 10% chance for X-class solar flare in next two days.Space Weather Message Code: ALTTP4Serial Number: 473Issue Time: 2014 Aug 25 1539 UTCALERT: Type IV Radio EmissionBegi… »

Muon Detection Tests Begin In Japan Towards Fuel Detection at Fukushima Daiichi

A sample testing box set was tested at JAEA’s Tokai reactor in late July. The tests helped them come up with what they think will be proper shielding for the detectors. IRID reports that they think about 10cm of shielding should be enough to enable detectors to be installed at Fukushima Daiichi.

There will still be considerable challenges to an actual installation. In order to do the actual detection on the containment structure of each reactor, one of the two muon units will need to be buried near the reactor buildings. Contaminated groundwater and underground structures pose problems with this. High levels of contamination outside the reactor buildings also pose problems with operating the detectors and to actually place the containers. Areas such as the 10,000 sievert readings near the unit 1 & 2 vent tower may pose considerable problems for installing equipment near those buildings.
