The organization of the association are: the Council and the General Assembly, the Executive Board made of the elected Executive Board members, representing the different national and regional chapters, the Legal Auditors and the Court of Arbitration.

1. The Council is made up of all the members, represented by their nominated representatives. The Council meets at least once a year. One meeting is dedicated to the General Assembly.

2. The General Assembly is the assembly of members as defined in the Association Law 2002. From 2023, a regular General Assembly will be held once a year in Vienna, aside from the IAEA General Conference.

3. An exceptional General Assembly will take place upon: a) A decision by the Executive Board, b) An application by the regular General Assembly, c) The request of the Legal Auditors (§ 21, part 5, second sentence; § 11 part 2 third sentence of Vereinsgesetz2 2002), e) A request by at least 25% of all members. This extraordinary General Assembly will be held in an appropriately timely manner.

4. All members are to be invited by email (to the email-addresses provided to the association by the members), to the Council meetings, the regular and extraordinary General Assemblies at least 45 days prior to the date. The agenda of the meetings shall be announced. The meeting is convened by the Chair of the INSC, also Chair of the Executive Board.

5. Requests to the General Assembly shall be submitted at least two weeks before the date of the General Assembly.

6. All members are entitled to participate in the Council meetings and General Assembly. Only the officially nominated representatives of members are entitled to vote. Each nominated representative has one vote. The transfer of voting rights to another member (proxy) by written authorization is permitted. The information needs to be provided to the secretary at least one week in advance of a meeting.

7. The Council and General Assembly can take decisions if the quorum of half the total number of nominated representatives plus one is attained. Decisions should be by consensus. If consensus cannot be reached, votes can take place, in which case by simple majority (the vote of the INSC Chair counting twice in case of equality). Decisions amending the statutes of the association or dissolving the association, however, require a qualified majority of twothirds of the valid votes cast.

8. The Chair shall preside at the Council and the General Assembly meetings. If the Chair is unable to do so, the first Vice Chair shall take over. If this is also not possible, the second Vice Chair will preside.
