5. Title, number of pages  and language(s)  of the notified document:  Draft 
Implementing Decree on the requirements for nuclear installation design (57 pages, in 
Czech; 58 pages, in English)   
6. Description of content:   
Based on authorising provisions in the new Atomic Act, the draft implementing decree 
governs:  
1) the requirements for the contents of documentation for licensed activities,  
2) a list of safety functions that must be performed  by nuclear installations and 
classification of the functions into categories according to their relevance to nuclear safety,  
3) safety classes and the criteria for classifying selected equipment into these classes,  
4) the method of ensuring defence -in-depth, and  
5) the content of the requirements for nuclear installation design referred to in § 46(1), 
(2)(a), (b), (e), (g), (i), (k), (l), and (m), and (3) of the Atomic Act. As regards the 
implementation of § 46(8) of the Atomic Act, the implementing decree  lays down detailed 
requirements for  G/TBT/N/CZE/203  
 
- 2 - 
 
  1) the designing of nuclear installations in a manner ensuring nuclear safety, radiation 
protection, radiation situation monitoring, radiological emergency management, security 
and non -proliferation of nuclear weapons t hroughout their life cycle,  
2) nuclear installation design in terms of  
a) compliance with safety objectives,  
b) compliance with the principles of the safe use of nuclear energy,  
c) resilience and protection of nuclear installations against the hazards resu lting from the 
characteristics of the location where the nuclear installation is sited and from external 
influences,  
d) prevention, resilience and protection of the nuclear installation against internal 
influences,  
e) requirements for selected equipment in  terms of the safety functions to the 
performance of which it contributes,  
f) compliance with the requirements for the technical means of radiation protection 
assurance,  
g) compliance with the requirements for radiological emergency management,  
h) complian ce with the requirements for security, and  
3) the design basis and proven methods, procedures and technology in the design process.  
7. Objective and rationale , including the nature of urgent problems where applicable: 
In connection with the adoption of th e new Atomic Act, it is necessary to lay down, among 
other things, detailed requirements for nuclear installation design, in accordance with the 
authorising provisions in this Act. The objective of the draft legislation is to lay down a 
number of details r elated to the design of nuclear installations sited or operated in the 
territory of the Czech Republic in connection with the obligations set out by the Atomic Act 
and in consideration of the existing, tried and tested system. In addition to the relevant 
provisions of the Atomic Act, the draft implementing decree is conceptually based on 
legislation that has governed this area until now, i.e. Implementing Decree No 195/1999 
on the requirements for nuclear safety, radiation protection, physical protection an d 
emergency preparedness, Government Regulation No 11/1999 on emergency planning 
zones, Implementing Decree No 307/2002 on radiation protection, and Implementing 
Decree No 319/2002 on the function and organisation of the national radiation monitoring 
netwo rk, which were repealed as of the date of entry into force of the new Atomic Act and 
need to be replaced with new legislation.  
The nuclear installation design process and the actual design are the basic prerequisites for 
peaceful use of nuclear energy. All  nuclear installations must be designed and operated in 
a manner ensuring a whole set of safety aspects, i.e. nuclear safety, radiation protection, 
technical safety, radiation situation monitoring, radiological emergency management and 
security, throughout  their life -cycle. The requirements set out by the nuclear installation 
design must ensure compliance with the basic safety functions, which are as follows:  
1. allow, if necessary, for immediate and safe shut -down of the nuclear reactor and for 
maintaining  it in a subcritical state,  
2. prevent the uncontrolled development of a fission chain reaction,  
3. make it physically impossible for a critical or supercritical state to develop outside the 
inner part of the nuclear reactor,  
4. ensure dissipation of the h eat produced by nuclear fuel and technological systems, and  
5. ensure shielding and prevent the release of radioactive substances and the propagation 
of ionising radiation into the environment.  
The draft implementing decree does not contain any references to technical standards or 
other similar rules, nor does it render any such documents binding.  
The draft implementing decree has also been notified in accordance with Article 33 of the 
Treaty establishing the European Atomic Energy Community, as a regulatio n containing 
basic safety standards for the protection of peaceful use of nuclear energy and ionising 
radiation.
