Professor Yong Hoon Jeong's research lab specializes in advanced energy systems and environmental sustainability, with a strong focus on nuclear thermal propulsion for deep space exploration and innovative water splitting technologies for clean hydrogen production. The lab investigates critical thermal-hydraulic phenomena such as critical heat flux in reactor systems and explores sustainable solutions for environmental management in large-scale water bodies like reservoirs. Their work bridges nuclear energy applications with environmental engineering, aiming to enhance safety, efficiency, and long-term ecological balance.

The critical heat flux (CHF) on the reactor vessel outer wall was measured using the two-dimensional slice test section. The radius and the channel area of the test section were 2.5 m and 10 cm × 15 cm, respectively. The flow channel area and the heater width were smaller than those of the ULPU experiments, but the radius was greater than that of the ULPU. The CHF data under the inlet subcooling of 2 to 25°C and the mass flux 0 to 300 kg/m2·s had been acquired. The measured CHF value was general
Although the harsh space environment imposes many severe challenges to space pioneers, space exploration is a realistic and profitable goal for long-term humanity survival. One of the viable and promising options to overcome the harsh environment of space is nuclear propulsion. Particularly, the Nuclear Thermal Rocket (NTR) is a leading candidate for near-term human missions to Mars and beyond due to its relatively high thrust and efficiency. Traditional NTR designs use typically high power reac
새만금 방조제 건설로 조성된 새만금호의 장기적인 수질의 변화를 조사하기 위해 2002년부터 2010년까지 총 40회에 걸쳐 현장조사를 수행하였다. 호 내 표층수의 염분은 방조제 끝물막이 직후 감소하여 장기간 감소된 상태를 유지하였다. 방조제 끝물막이 직후에 표층수의 SPM은 감소하였으나, 이후 호 내 수위 변동과 관련하여 증가하다 다시 감소하는 경향을 보였다. 표층수의 Chl-a는 방조제 끝물막이 직후부터 증가하여 장기간 동안 계속 증가된 상태를 유지하였다. 표층수의 DIN 항목들은 방조제 끝물막이 직후에는 변화가 없었으나, 이후 NHSUB4-/SUBN은 증가(90%)하였다. 표층수의 DIP는 방조제 끝물막이 직후에는 감소하였으나, 이후 증가(264%)하였다. NHSUB4-/SUBN과 DIP의 증가는 새만금호의 장기적인 유기물의 축적과 관련된 것으로 판단된다. 표층수의 NOSUB3-/SUBN은 방조제 끝물막이 이후 변화가 없는 반면, DISi는 방조제 끝물막이 직후부터 증가하여 계속
