The US National Nuclear Security Administration (NNSA) will furlough approximately 1,400 employees as the government shutdown enters its 20th day, leaving fewer than 400 staff to manage the nation's nuclear stockpile.

• This marks the first time the NNSA has furloughed workers since its establishment in 2000.
• Energy Secretary Chris Wright indicated that while the nuclear stockpile remains secure, the furloughs will hinder efforts to modernize older weapons.
• The shutdown stems from an impasse between Republicans and Democrats over budget negotiations, specifically concerning healthcare funding.
