In this paper the effect of different aircraft automated descent guidance strategies on fuel burn and the temporal predictability of the executed trajectory is investigated. The paper aims to provide an understanding of how airborne automation can be permitted by Air Traffic Control to remain in control of the descent in the presence of disturbances while providing sufficient predictability. Si...

This paper investigates whether a fusion power plant could be designed to be passively proliferation-proof. Even low neutron production rates enable fissile-fuel breeding, so such a fusion reactor must burn neutron-lean fuels. To burn these fuels economically requires a highpower-density fusion concept, and a D-He field-reversed configuration will be analyzed here. The paper discusses physics a...

A configuration made up of two nested magnetically insulated transmission lines, the inner one carrying a high voltage lower current – and the outer one a high current lower voltage – pulse, was in a previous communication proposed for the ignition of a magnetic field assisted thermonuclear detonation wave. Unlike the fast ignition concept, it does not require the compression of the DT fusion f...

Wildfire simulation modelling was used to examine whether fuel reduction treatments can potentially reduce future wildfire emissions and provide carbon benefits. In contrast to previous reports, the current study modelled landscape scale effects of fuel treatments on fire spread and intensity, and used a probabilistic framework to quantify wildfire effects on carbon pools to account for stochas...

A review has been performed of the current method of forecasting CO2 emissions fromaircraft using UK airports. The current approach uses the CORINAIR Guidebook data tocalculate the fuel burn by individual aircraft on each route. The assessment has coveredthe mapping of aircraft types to those in CORINAIR, the accuracy of the data (bycomparison with data from the AERO2k greenhous...

Fast spectrum reactors are essential for the future of nuclear energy. Therefore, there is a need continuous research and development design safety current fast reactors. The aim this work to analyze process fuel burnup in large scale (3600 MWth) Sodium cooled Reactor (SFR) core. This called European (ESFR). It proposed 7th Framework Programme within Euratom Framework. A new version (version 2....

The instant release fraction of a spent nuclear fuel is a matter of concern in the performance assessment of a deep geological repository since it increases the radiological risk. Corrosion studies of two different spent nuclear fuels were performed using bicarbonate water under oxidizing conditions to study their instant release fraction. From each fuel, cladded segments and powder samples obt...
