The present report considers the EU Action Plan to enhance preparedness against chemical, biological, radiological and nuclear security (CBRN) risk, adopted in 2009 by the EU Council. The Action Plan‟s overall goal is to reduce the threat of, and damage from, CBRN incidents of accidental or intentional origin, including terrorist acts. The Plan provides possibilities for the EU member states to implement the listed standards by including them into the national legislation. The National Program developed subsequently in Bulgaria for the implementation of the EU CBRN Action Plan is also analyzed. The strengths and weaknesses of the document are revised as well as the progress of its implementation.
