5  NUCLEAR MATERIALS
 

Accountancy and control of nuclear materials Inspection program of UJD in the area of accountancy and control of nuclear materials results from the requirements of the Agreement between the Government of the Slovak Republic and the IAEA on application of safeguards on nuclear materials. Within the Slovak legislation this activity is performed according to the regulation of CSKAE No. 28/77 Coll. In 1998 there were 41 inspections, of which 31 were made in co-operation with the IAEA inspectors. The main purpose of inspections performed together with the IAEA was inspection of fresh and spent fuel in EBO NPPs and EMO NPP, as well as inspection of spent fuel prepared for transportation to abroad:

  • at A-1 NPP inspection of spent fuel assemblies was based on an indirect method (due to high radiation at the fuel location), i.e. inspection through surveillance equipment of the IAEA. In 1998 4 transports of spent fuel prepared for transportation to the Russian Federation were checked;

  • at the interim spent fuel storage containers with spent fuel from EBO V-1 and V-2 NPPs were checked using Cherenkov camera, and in the case of low intensity, for assemblies with long cooling period, using a device checking the presence of gamma radiation;

  • at EBO V-1 and V-2 NPPs fresh fuel was checked at the storage of fresh fuel, spent fuel loaded in fuel ponds and also fuel loaded into the core of each reactor after refueling. At the same time during each inspection integrity of seals was checked and the record of surveillance equipment was evaluated;

  • At EMO NPP fresh fuel was checked located at the storage of fresh fuel. One inspection focused on installation and testing of surveillance equipment of the IAEA EMINI at unit 1. Other inspections were focused on service of surveillance equipment. In May 1998 physical inventory of nuclear materials was done, together with verification of fuel loaded in the core of reactor unit 1.

Another area of inspection of nuclear materials was inspection of holders of nuclear materials outside of nuclear installations on the whole territory of Slovakia.

There were 10 inspections of UJD. Regulatory activity in the area of accountancy and control of nuclear materials included also checking and procession of reports from the holders of nuclear materials, preparation and sending advance notifications, special and accounting reports for the IAEA according to the subsidiary arrangements to the Agreement and according to the regulation of CSKAE No. 28/77 Coll.


Physical protection of nuclear installations and nuclear materials

The main focus of UJD in this field was inspection of the automated security system of EBO NPPs (AKOBOJE) and gradual introduction of a similar security system AKOBOJE EMO NPP into operation at the time of preparations for beginning of the physical and energy commissioning of unit 1 of EMO NPP.

In connection with the gradual reconstruction of EBO V-1 NPP and the interim spent fuel storage, UJD issued its approval for changes related to the physical protection at EBO NPPs so that the contractors could continue in their work on approved projects without interfering with existing physical protection system.

Physical protection of EBO NPPs was still secured by a private security service 5 Košice which has the approval of UJD to perform security service in co- operation with the police response forces until the end of 1999.

Completion certificate of 21.5.1998 issued by the regional authority in Nitra permitted the use of AKOBOJE EMO NPP in the scope of phase 1, by which the system was put into a trial operation still before the beginning the physical commissioning of unit 1 EMO NPP.

During the trial operation of the AKOBOJE EMO NPP security system UJD inspectors made inspections of physical protection focusing on checking conformity of the status of installations included in phase I of construction of AKOBOJE, which is to be put into permanent operation, with the status described in the safety documentation related to the above-stated system. In parallel with preparation of putting the phase I system into permanent operation, launching of the trial operation of phase II of this system in a way not to disturb the integrity of the whole system was prepared. It is assumed that phase II of the system will be launched into trial operation still before the planned beginning of physical commissioning of unit 2 of EMO NPP.

Based on the application of the EMO NPP operator, UJD issued its approval for further service by the private security service 5 Košice for a period of 1 year.

During 1998 UJD made 12 inspections of physical protection of nuclear installations and nuclear materials.

Shortcomings found during these inspections were resolved by the operator continuously according to the measures imposed by UJD. In one case, when UJD found serious shortcomings at EMO NPP, UJD initiated an administrative proceeding on imposing a fine on the operator - EMO NPP. During 1998 there were also inspections of physical protection during transportation of fresh fuel from the Russian Federation to EBO NPPs, and spent fuel from A-1 NPP to the Russian Federation.


Transportation of nuclear materials

Approval of package design and transport of nuclear materials and radioactive waste was made in compliance with Act No.28/1984 on state supervision over nuclear safety of nuclear installations, from 1.7.1998 according to Act No. 130/1998 Coll. on peaceful use of nuclear energy and according to the UJD document: "Conditions for transportation of nuclear materials on the territory of SR". This document contains requirements of the IAEA for safe transport of radioactive materials. All transports of nuclear materials in 1998 were made in compliance with conditions of the UJD approval. No serious shortcomings were found.

There were 5 transports of fresh fuel from the Russian Federation to EBO NPPs during the evaluated period.

The fuel is stored in storage facilities for fresh fuel at the sites of EBO V-1 and V-2 NPPs.

There was 1 transport of uranium concentrate coming from the Czech Republic through the territory of Slovakia to the Russian Federation. Spent fuel cooled for 3 years in the pools from all 4 units of EBO NPPs was transported to the SE-VYZ interim spent fuel storage. In 1998 transportation of spent fuel from A-1 NPP into the Russian Federation continued. In four transports T-15 container was used for transportation of fuel assemblies. Before each transport of spent fuel UJD made an inspection focusing on checking the readiness of transportation. No serious shortcomings were found.

Illicit trafficking with nuclear and radioactive materials

In 1998, in compliance with the resolutions of the Government of Slovakia, implementation of technical and legislative measures was completed focusing on prevention of illicit trafficking of nuclear and radioactive materials. During 1998 there was one case of seized smuggled radioactive material - in July 1998 the police detained a person at the Bratislava airport carrying illegally alpha source.

UJD has continued in its co-operation with the IAEA in updating the IAEA database on illicit trafficking with radioactive materials.
