The Nuclear Reactor Renaissance: Space Exploration and National Security

Posted by in categories: climatology, nuclear energy, security, solar power, space travel, sustainability

The nuclear power sector is seeing a resurgence in innovation, supported by new policies and emerging technologies. The general public and various governments are starting to grasp the value of nuclear power as an alternative, sustainable energy source. Unlike renewables, such as wind and solar power, nuclear energy is not dependent on weather conditions for power generation, having a capacity factor of over 90 percent. Nuclear power is also more eco-friendly than natural gas and coal and its “carbon-free” attributes are seen as critical in the fight against climate change.

For decades, advancements in the nuclear power sector have been incremental and focused largely on making systems “walk away safe.” Today, the industry is pushing the boundaries and exploring applications for nuclear power in ways that have never before been considered.

BWXT is at the forefront of this nuclear renaissance. This 6,000-employee company operates on the model of letting capital drive strategy. BWXT is constantly evaluating new ways to ensure workers, funding, and policies are utilized in the most effective way possible. The company also analyzes the needs of numerous other industries to determine how nuclear power could provide innovative solutions.

Method of making oxygen from water in zero gravity raises hope for long-distance space travel

Posted by in categories: nanotechnology, space travel

In the new study, the researchers dropped the full experimental set up for photocatalysis down a 120m drop tower, creating an environment similar to microgravity. As objects accelerate towards Earth in free fall, the effect of gravity diminishes as forces exerted by gravity are cancelled out by equal and opposite forces due to the acceleration. This is opposite to the G forces experienced by astronauts and fighter pilots as they accelerate in their aircraft.

The researchers managed to show that it is indeed possible to split water in this environment. However, as water is split to create gas, bubbles form. Getting rid of bubbles from the catalyst material once formed is important – bubbles hinder the process of creating gas. On Earth, gravity makes the bubbles automatically float to the surface (the water near the surface is denser than the bubbles, which makes them buyonant) – freeing the space on the catalyst for the next bubble to be produced.

In zero gravity this is not possible and the bubble will remain on or near the catalyst. However, the scientists adjusted the shape of nanoscale features in the catalyst by creating pyramid-shaped zones where the bubble could easily disengage from the tip and float off into the medium.

Internally, NASA believes Boeing ahead of SpaceX in commercial crew

Posted by in category: space travel

Based on NASA’s “schedule risk analysis” from April, the agency estimates that Boeing will reach this milestone sometime between May 1, 2019, and August 30, 2020. For SpaceX, the estimated range is August 1, 2019, and November 30, 2020.


Both of the companies are well behind schedule, forcing the agency to scramble.

Turbo inductor cogeneration with MSR nuclear can economically replace oil

Posted by in categories: engineering, nuclear energy, space travel

Bucknell has led advanced engineering teams at Chrysler and General Motors for three production high performance engine families. Was Senior Propulsion Engineer for the Raptor full-flow staged combustion methalox rocket at Space Exploration Technologies then Senior Propulsion Scientist for Divergent3D developing vehicle technologies.

In 2017, he described how high temperature (820−1000 degree celsius) nuclear power plants can solve produce synthetic fuel to replace oil.

The End of the Old Solar System, the Beginning of the New

Posted by in category: space travel

Today marks not one but two milestones in planetary exploration. It is the 25th anniversary of Voyager 2’s flight past Neptune, the most distant planet ever seen up close. It is also the exact day that the New Horizons spacecraft is crossing Neptune’s orbit on its way to Pluto, the mysterious world that marks the boundary between the solar system we know and the one we don’t.

X-SpaceX Raptor designer has ready for development designs for nuclear rocket that will be up to 7 times better than BFR

Posted by in categories: nuclear energy, solar power, space travel, sustainability

John Bucknell created the pre-conceptual design for the SpaceX Raptor engine. It will be the advanced full-flow staged combustion rocket engine for the SpaceX BFR. He designed and built the subscale Raptor rocket for proof of concept testing able to test eighty-one configurations of main injector.

John Bucknell says the nuclear turbo rocket technology and his designs are ready for development. The air-breathing nuclear thermal rocket will enable 7 times more payload fraction to be delivered to low-earth orbit and it will have 6 times the ISP (rocket fuel efficiency) as chemical rockets. The rocket will have two to three times the speed and performance of chemical rockets for missions outside of the atmosphere.

The fully reusable nuclear rocket will be a single stage to orbit system which will be able to make space-based solar power several times cheaper than coal power. Using the 11-meter diameter version of this rocket to build space-based solar power will enable solar power at less than 2 cents per kilowatt-hour.
