Amolten salt reactor using thorium-232 as a blanket and uranium-233 as the fuel is being planned to run entirely off of the u-233 produced from the blanket. it is currently being fueled only by u-235. because the th-232 in the blanket can be pumped continuously from the blanket surrounding the core, pa-233 can be extracted before any radiative capture can occur, thereby removing any losses of pa-233 due to neutron absorption. the pa-233 is stored in a container and the u-233 is accumulated outside the core. a. write down the nuclear reactions that will lead to the production of u-233 from the neutron capture of th-232. why can you ignore th-233 for the rest of this problem? b. set up the rate equations you would use to analyze the pa-233 and u-233 content over time. c. how much th-232 would be needed produce 200 kg of u-233 fuel from the blanket in one year? you can keep your answers in terms of number of atoms. q = 1014 neutrons/cm² s oc of th-232 = 8 barns

d. air pressure decreases as altitude increases.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
