For safe disposal of radioactive waste, we have to verify
that waste packages meet the acceptance criteria of disposalfacilities. Various data needed for this verification has to be
managed systematically, retrievable for a long period of time
according to their relation to other data ranging fromgeneration to disposal. Also, this data is needed for thedesign of treatment and disposal facilities. Therefore, we aredeveloping the “Waste Management System” to manage all
waste data with traceability and to analyze and count the data.
We have to prepare a large amount of data for quality
assurance (QA data) of the waste packages used at stages
from waste generation to final conditioning for disposal, suchas generation status, waste treatment methods (incineration,compaction, etc.), materials used for solidification, calibration
certificates of measurement instruments, records of worker’s
training and so on. Examples of the data to be managed inthis system are listed in Table 9-2.
In addition, we have to handle the waste data to be used fordesign of waste treatment and disposal facilities and forconsidering waste disposal systems. These data are managed
as “Optimization Study and Information Service data (OSISdata)” in this system.

The Waste Management System consists of following fourfunctions working upon the QA data and the OSIS data as
shown in Fig 9-4.
(1) QA analytical function: Supporting technical documentation
for quality assurance of each waste package by analyzing
characteristics of each waste material.
(2) OSIS analytical function: Supporting estimation ofradioactivity in each waste package and total waste
package volume, design of waste treatment and disposal
facilities, and so on.
(3) QA management function: Managing QA data of eachwaste package so as to have traceability.
(4) OSIS management function: Managing the OSIS data.
In our conception, the “Waste Management System” hasdata management functions and analytical functions that areconnected through networks to PC & servers.
In the future, we will construct the concrete “WasteManagement System” to be used for verification of actual
waste packages, applying each of the above functions toactual QA and OSIS data. This system will be incorporated in
the individual waste management systems in each of ourR&D sites.
