Reaffirm commitment to ban nuclear tests, UN chief says in message for International Day,  UN News 29 Aug 21  Countries which have not yet ratified the Comprehensive Nuclear-Test-Ban Treaty (CTBT) are urged by UN Secretary-General António Guterres to do so without delay.
The UN chief made the appeal in his message for the International Day Against Nuclear Tests, observed on Sunday, 29 AugustThe UN chief made the appeal in his message for the International Day Against Nuclear Tests, observed on Sunday, 29 August

The date marks the 30th anniversary of the closure of the Semipalatinsk nuclear test site in Kazakhstan, the largest of its kind in the former Soviet Union, where more than 450 nuclear devices were exploded over four decades.

Terrible consequences

Mr. Guterres said nuclear tests caused enormous human suffering and environmental damage.

They had terrible consequences on the health of people living in affected areas.  Many were relocated from their ancestral lands, disrupting their lives and livelihoods.  Pristine environments and ecosystems were destroyed, which will take decades, if not centuries, to heal.”

The closure of the Semipalatinsk test site signaled the end of the era of unrestrained nuclear testing, said Mr. Guterres.  Soon afterwards, countries began negotiating the CTBT.

The treaty bans all explosive nuclear weapons tests anywhere, by any country, he added, effectively “putting a brake on the nuclear arms race and providing a powerful barrier to the development of new nuclear weapons.”

No excuse

The CTBT was adopted in 1996 and has been signed by 185 countries, and ratified by 170, including three nuclear weapon States.  However, it must be signed and ratified by 44 specific nuclear technology holder countries before it can enter into force……………….


Threat still real: Kazakhstan Ambassador

The threat that nuclear weapons pose to the world remains “as realistic as ever”, said Kazakhstan’s Ambassador to the UN, Magzhan Ilyassov, speaking to UN News ahead of the International Day (interview here and at right). 

“For us, the 29th of August is not a day in the calendar. It is a reminder about how traumatic nuclear tests can be for humankind because in Kazakhstan alone, 1.5 million people still suffer, and will unfortunately suffer for future generations, from genetic diseases, cancer, leukaemia, which were caused by exposure to nuclear tests.”

Mr. Ilyassov said the total impact of the nuclear explosions carried out at the Semipalatinsk site was “1,200 times more” than the atomic bomb dropped on Hiroshima, Japan, during the Second World War.

“The test site itself is of the size of Israel, so it’s a big chunk of the territory of Kazakhstan and that cannot be used for any other purpose like agriculture for many, many decades now,” he said, adding “so with that, we can also project what was the damage caused by other nuclear test sites around the world which were eventually closed.”  https://news.un.org/en/story/2021/08/1098682

Vulnerability of Louisiana’s Waterford 3 nuclear plant to storm surge

Intensifying Hurricane Ida a significant threat to key infrastructure.   Ida is forecast to hit the industrial corridor between Baton Rouge and New Orleans, site of three key ports, petrochemical sites, and a nuclear power plant.

Vulnerability of Waterford 3 nuclear plant to storm surge. Although it lies 65 miles inland from the south coast of Louisiana, the Waterford 3 nuclear generating station, located at an elevation of 10-15 feet on the south shore of the Mississippi River, is vulnerable to storm surge from a major hurricane. Hurricane Betsy, a category 4 storm that hit Louisiana in 1965, brought a storm surge to the edge of the plant’s location (Figure 3 on original).

According to a 2019 analysis by Bloomberg, the Waterford 3 plant is designed to withstand a maximum storm surge of 23.7 feet above sea level, or about 10 feet higher than the plant’s elevation. According to NOAA’s National Storm Surge Hazard database, a worst-case category 3 hurricane could flood the plant to a depth of 3’, while a worst-case category 4 hurricane could flood the plant to a depth of more than 9’ – near its design limit. Fortunately, storm surge modeling by Louisiana State University using the 11 a.m. EDT Saturday NHC forecast showed Ida’s storm surge stopping just short of the plant (Figure 4 on original)

After the 2011 disaster at Japan’s Fukushima nuclear power plant, the Waterford 3 plant moved to store all of its emergency generators, pumps, and other essential safety equipment in a 30-foot flood-proof concrete bunker – a system called Flex, for Flexible Mitigation Capability. The bunker has manually operated and powered sump pumps to remove water in the event of a flood.
