The main component of C-14 contained in radioactive solid waste of PWR has an organic form.It is estimated that the main source of organic component of C-14 flowed out of the resin of the reactor coolant system. Therefore, distribution coefficients of C-14 to mortar materials were obtained using actual solid waste, and the effect on burial disposal was evaluated.
