Nuclear submarine

Nuclear submarines require only 4 kilograms of uranium to power them for 30 years without refueling. The reactors used in nuclear submarines are based on highly enriched uranium, which contains 90% or more uranium-235. This enriched uranium can produce large amounts of energy in small quantities.

4-5 kilograms of enriched uranium can power a nuclear submarine for decades, because nuclear fission reactions produce a lot of energy. The energy produced by the fusion of one kilogram of uranium-235 is equivalent to about 24,000,000 kilowatt hours.

The efficient use of fuel in a nuclear reactor and the design of the reactor itself eliminate the need for frequent refueling. Nuclear submarines do not require refueling for 20-30 years, which is a significant technological advantage for their long-term missions.

This is why nuclear submarines have greater autonomy than traditional diesel-electric submarines.

جوہری آبدوز

جوہری آبدوزوں کو 30 سال تک ایندھن بھرے بغیر طاقت دینے کے لیے صرف 4 کلوگرام یورینیم کی ضرورت ہوتی ہے۔ جوہری آبدوزوں میں استعمال ہونے والے ری ایکٹر انتہائی افزودہ یورینیم پر مبنی ہیں، جس میں 90% یا اس سے زیادہ یورینیم-235 ہے۔ یہ افزودہ یورینیم چھوٹی مقدار میں بڑی مقدار میں توانائی پیدا کر سکتا ہے۔

۔4-5 کلو گرام افزودہ یورینیم کئی دہائیوں تک ایک جوہری آبدوز کو طاقت دے سکتا ہے، کیونکہ نیوکلیئر فِشن ری ایکشنز بہت زیادہ توانائی پیدا کرتے ہیں۔ ایک کلوگرام یورینیم-235 کے فیوژن سے پیدا ہونے والی توانائی تقریباً 24,000,000 کلو واٹ گھنٹے کے برابر ہے۔

جوہری ری ایکٹر میں ایندھن کا موثر استعمال اور خود ری ایکٹر کا ڈیزائن بار بار ایندھن کی تبدیلی کی ضرورت کو ختم کرتا ہے۔ نیوکلیئر آبدوزوں کو 20-30 سال تک ایندھن کی تبدیلی کی ضرورت نہیں ہوتی، جو ان کے طویل مدتی مشنوں کے لیے ایک اہم تکنیکی فائدہ ہے۔

یہی وجہ ہے کہ جوہری آبدوزوں کو روایتی ڈیزل الیکٹرک آبدوزوں کے مقابلے میں زیادہ خود مختاری حاصل ہے۔

liquid water discovered on Mars

liquid water discovered on Mars This is the first clear evidence of liquid water, not just frozen ice, discovered on Mars. A groundbreaking discovery published in Science has confirmed that Mars once had liquid water, offering new insights into the planet’s climate and potential for supporting life.  Researchers analyzing data from NASA’s Curiosity rover identified ancient "wave ripples" in rocks at the Gale Crater region, dating back 3.7 billion years. These ripples, formed by wind and water, indicate the presence of a shallow, open-air lake about 2 meters (6.5 feet) deep.  The discovery highlights a time when Mars had a warmer climate and a thicker atmosphere capable of sustaining liquid water — a critical ingredient for life as we know it. This revelation has far-reaching implications for understanding Mars' habitability and planning future missions.  The presence of liquid water raises the possibility that microbial life once thrived on the planet. Additionally, remna...

A black diamond

A black diamond that is actually an apple? Of course, you have seen apples of various colors including green and red, but there is one region in the world where black apples grow. By the way, the color of this apple is deep violet, but it looks black, which is why it is called in English  (black diamond apple)  is called and it is found only in Tibet. The black diamond apple stands out from other apples due to its luxurious appeal and rarity and also arouses people's curiosity. The distinctive color of the black diamond apple is actually attributed to the unique geographical location of Ningchi, a small town nestled among the mountains in the Tibet Autonomous Region of China. Apples found at high altitudes are exposed to intense ultraviolet light during the day, causing significant temperature fluctuations. Such climatic conditions contribute to the production of the characteristic black color of the apple. Although the inside of the black diamond apple is like a regular apple...

Strong and secure shelters Switzerland is the only country in the world that can evacuate all its citizens (114%) to underground safe rooms, whenever an emergency occurs. There are more than 300,000 strong and secure shelters, all of which can shelter a total of 8.6 million people, compared to the country's current population of 8.3 million. Switzerland's security system is highly organized and prepared for all types of emergency situations, making it unique worldwide. The special feature of this system is that it is capable of sheltering not only every citizen but also additional persons, and its structure is based on the following features: 1. Number and capacity of underground shelters There are more than 300,000 shelters in Switzerland, most of which are underground and made of reinforced concrete. These shelters can provide protection to a total of 8.6 million people, compared to the country's current population of about 8.3 million. This means that space is reserved f...
