II a p p r o v e s
the design type of -KODA VPVR/M cask as an S type for storage of spent nuclear fuel - fuel assemblies or fuel elements from research nuclear reactors as described in Condition No. 2 of this Resolution - in a relevant storage facility.
The cask for storage of nuclear materials meets the requirements of Act No.18/1997 Coll. and Regulation No. 317/2002 Coll., on type approval of casks for transport and storage of nuclear materials and radioactive substances, on type approval of ionizing radiation sources and on transport of nuclear materials and defined radioactive substances (on type approval and transport), in the version in force on the date of commencement of the administrative procedure.
-KODA VPVR/M Cask Description
-KODA VPVR/M cask (cask) consists of a cylindrical body which is reduced in its top and bottom parts with a rounded transition.
Placed in the inner cask space of a cylindrical shape with a smooth surface provided with aluminum spray is a basket of atabor sheets consisting of 36 square cells for fuel and a central hole for the basket suspension. A system of two upper and two lower lids provided with gaskets is used to close the cask. Each of the lids is screwed independently to the cask body.
The upper primary lid consists of a thick-wall cylindrical plate with a diameter of 630 mm. In the lid centre, there is a hole for inserting the basket central suspension. There are holes in the lid for drying the cask inner space before sealing the secondary lid and also holes for the basket tie rods. The lower primary lid is analogical as regards dimensions with the upper lid.
In the centre of the lid, there is a threaded hole for fixing the central suspension and threaded holes for the basket tie rods.
The upper secondary lid is a circular plate, on the inner front surface provided with a recess inserted into the body inner recess fixing thus the lid together with eight guide feathers against undesirable external force effects. The guide feathers are screwed along the lid perimeter. Made in the lid there is a receiver of the valve for vacuuming and filling the cask with helium. The receiver is covered with a massive cap. The lower secondary lid is dimensionally analogous to the upper one, however, there is no receiver. Each of the secondary lids is screwed to the body with 16 screws M36. The inner space between the primary and secondary lids is used for monitoring the cask leak tightness.
The cask is manufactured by -KODA JS a. s., Orlík 266/15, 316 00 Plze - Bolevec.

Rationale:
SÚJB commenced administrative procedure with the pa rty to the procedure in the matter of the cask type approval based on application No. JS-OBCH/464/16 of 19 December 2016 submitted by the party to the procedure which was received by SUJB on 21 December 2016.
Since the administrative procedure in the above matter was commenced under Act. No.
18/1997 Coll. and was not completed before the entry into force of Act No. 263/2016 Coll.
the Atomic Act, the State Office for Nuclear Safety in this matter, in accordance with the provision of Section 232 (6) of Act No. 263/2016 Coll., the Atomic Act, completed the administrative procedure and assessed the rights and obligations related to it according to the existing legislation.
Resolution ref. No. SÚJB/ONRV/12586/2017 9/10
The Resolution is being issued after examining the submitted documentation that was submitted to the State Office for Nuclear Safety in accordance with the provision of § 23 of Act 18/1997 Coll. and according to § 3 and § 4 of Regulation No. 317/2002 Coll., on type approval and transport.
The party to the procedure filed the application for a repeated issue of the Resolution on type approval of VPVR/M cask which was issued by SÚJB several times, and lastly under File No.
SÚJB/ONRV/5637/2011 of 14 March 2011, valid until 31 October 2016, due to the expiry of the above cited SÚJB Resolution.
The application was in compliance with the above cited provisions of the legislation supported by the below documentation for the repeated type approval of -KODA VPVR/M cask:
A certified copy of the excerpt from the Commercial Register for -KODA JS a.s. of 5 October 2016; Safety Report - Repeated issue of the Resolution on -KODA VPVR/M cask type approval, Ae 16782/Dok Rev. 0, -KODA JS a.s., of 13 December 2016; Technical Report - -KODA VPVR/M Cask, Events, their Evaluation and Inspections Carried out in the Years 2011 - 2016, Ae 16938/Dok Rev. 0, -KODA JS a.s., of 15 December 2016; Inspection and Service Plan of -KODA VPVR/M and Transfer Casks, Working Procedure file No. PP 2404 191, Rev. 0, ÚJV ez, a.s., valid since 31 March 2015; Utilization of -KODA VPVR/M Cask Package System supplied by -KODA JS a.s. to IAEA (US DOE) and ÚJV ez, a.s., Czech Republic.
The State Office for Nuclear Safety also took into consideration that the previous applications of the party to the procedure, based on which the Resolutions on VPVR/M cask type approval were issued, contained in the Supplements the Safety Documentation satisfying all requirements according to relevant provisions of Act No. 18/1997 and Regulation No.
317/2002 Coll., on type approval and transport.
The State Office for Nuclear Safety states that the submitted safety documentation meets the relevant provisions of Act No. 18/1997 Coll. and the relevant provisions of Regulation No.
317/2002 Coll., on type approval and transport, and proves the suitability of -KODA VPVR/M cask for its use for transport of radioactive content referred to in condition 1 and for storage of radioactive content referred to in condition 2 and in accordance with the other conditions of this Resolution.
The administration fee of CZK 1 000,- was paid as per Clause 107 (f) of the Supplement to Act No. 634/2004 Coll., on administration fees.
For the above reasons, SÚJB has decided as provided in the Resolution statement.
