Adds a nuclear industry

Description

In the IEA World Energy Extended Balances, there is a "Nuclear industry" Energy industry own use flow, but there is no "Nuclear industry" in transformation processes flows, which prevents from defining a nuclear industry in the PSUT. However, using the World Energy Extended Balances documentation, one can deduce from the amount of nuclear fuel used by "Main activity producer electricity plants" and "Main activity producer CHP plants" the energy transformation due to the nuclear industry. This function performs that task. The function is called within the specify_all() function.

main_act_producer_chp	A string identifying "Main activity producer CHP plants" in the flow column of the .tidy_iea_df. Default is IEATools::main_act_plants$main_act_prod_chp_plants.

Heat_Nuclear	A temporary column and product name added to the data frame, which identifies the production of heat by nuclear plants. Default is "Heat_Nuclear".
ratio_output_to_nuclear_fuel	A parameter that describes the correspondance between input of nuclear fuel and output of electricity and/or heat. The IEA World Energy Extended Balances state that the value adopted in the balances is 0.33, which is therefore the default value of the parameter.

Details

The World Energy Extended Balances documentation states that "The primary energy equivalent of nuclear electricity is calculated from the gross generation by assuming a 33% conversion efficiency. The calculation to be carried out is the following: gross electricity generation in TWh x0.086 / 0.33 = primary energy equivalent in Mtoe."

Hence this function does the following:

• the Nuclear fuel consumed by Main activity producer electricity & heat plants is ascribed to nuclear industry plants;

• the output of Main activity producer electricity and heat plants to be directed to nuclear plants is determined by multiplying their nuclear fuel consumption per 0.33. In the case of CHP plants, that output is divided into heat and electricity according to the shares of output of each of these two products;

• the output ascribed to nuclear plants is subtracted from Main activity producer electricity and heat plants.

Value

A modified version of the .tidy_iea_df, with a nuclear industry added as an additional transformation process.
