| Ensuring the Safety of Facilities
Through the Witness Inspection and Record Verification by Inspectors and Check Officers |
|
|
| The inspectors and check officers* of JNES perform
the following inspections and confirmations of various
facilities of the nuclear fuel cycle to ensure safety.
|
|
| - Pre-service Inspection |
|
For construction and modification works of nuclear fuel cycle facilities such as reprocessing facilities, nuclear facility inspectors* perform the witness inspection on the spot and the inspection based on the record verification method to check the construction records in order to verify the conformity of the construction to the approved design and construction methods and to the technical standards. |

| - Welding Inspection |
|
After the installation of the important equipment and
piping, welding inspectors* go to the site to confirm the integrity of welding work. The inspectors conduct the witness inspection on the spot using non-destructive testing methods such as radiograph tests and verification of documents and records of welding work. |
|
|
|
|
|
|
|
|
|
|
| - Periodic Facility Inspection |
|
The nuclear fuel cycle facilities, such as reprocessing
facilities, are subject to the periodic facility inspection conducted once a year during the operation. For the purpose of confirming that all the equipment and systems have enough safety performance specified by the operation license, the nuclear facility inspectors* perform the witness inspection and the record verification is conducted on the records of self-imposed inspection performed by the licensee. |
|
| - Confirmation on Consignments and Transport
Methods |
|
For the purpose of confirming that the raw uranium, fuel assembly and spent fuel are safely transported, consignments check officers* and the transport method check officers* conduct witness inspections and verification of documents and records, respectively on individual consignments and on transport methods. |
|
| - Confirmation on Waste Disposal and Waste
Disposal Facility |
|
For the purpose of confirming the safe disposal of low- level radioactive waste generated at nuclear power plants, the disposal check officers* and disposal facility check officers* conduct the witness inspection and verification of documents and records, respectively on the individual waste package and on the integrity of the waste repository facility. |
