following types of unclassified technical information relating to the regulation of 

safety, waste management, radiological safety, and environmental impact of 

designated nuclear energy facilities and to nuclear safety research programs: 

1. Topical reports concerning safety, waste management, radiological 

safety, and environmental effects written by or for one of the Parties as a 

basis for, or in support of, regulatory decisions and policies. 

2. Documents relating to significant licensing actions and safety and 

environmental decisions affecting nuclear facilities. 

3. ' Detailed documents describing the USNRC process for licensing and 

regulating certain U.S. facilities designated by the SORNS as similar to 

certain facilities being built or planned in Croatia equivalent documents on 

such facilities owned by Croatia. 

4. Information in the field of reactor safety research that the Parties have the 

right to disclose, either in the possession of one of the Parties or available 

to it, including light water reactor safety information from the technical 

areas described in Addenda "A" and "8," attached hereto and made a part 

of this Arrangement. Cooperation in these itemized research areas may 

require a separate agreement, as determined to be necessary by the 

research organizations of one or both of the Parties. Each Party shall 

transmit immediately to the other information concerning research results 

that requires early attention in the interest of public safety, along with an 

indication of significant implications. 

5. Reports on operating experience, such as reports on nuclear incidents, 

accidents and shutdowns, and compilations of historical reliability data on 

components and systems. 

6. Regulatory procedures for the safety, waste management, radiological 

safety, and environmental impact evaluation of nuclear facilities. 

7. Early advice of important events, such as serious operating incidents, 

government-directed reactor shutdowns, and emerging technical issues,

research and development, or those programs and projects under which 

activities are divided between the two Parties, including the use of test facilities 

and/or computer programs owned by either Party, shall be considered on a caseby-case basis and may be the subject of a separate agreement, if determined to 

be necessary by the research organizations of one or both of the Parties. When 

not the subject of a separate agreement, tt)e terms of cooperation may be 

established by an exchange of letters between the research organizations of the 

Parties, and shall be subject to the terms and conditions of the present 

Arrangement. 

Technical areas specified by such exchanges of letters may be modified 

subsequently by mutual consent. Temporary assignments of personnel by one 

Party in the other Party's Agency shall also be considered on a case-by-case 

basis and shall, in general, require a separate agreement between the research 

organizations of the Parties. 

C. Training and Assignments 

Within the limits of available resources and subject to the availability of 

appropriated funds, the USNRC shall cooperate with the SORNS in providing 

certain training and experience for SORNS safety personnel. Unless otherwise 

agreed, costs of salary, allowances, and travel of SORNS participants shall be

A This Annex is applicable to all cooperative activities undertaken pursuant to this 

Agreement, except as otherwise specifically agreed by the Parties or their 

designees. 

B. For purposes of this Agreement, "intellectual property" shall mean the subject 

matter listed in Article 2 of the Convention Establishing the World Intellectual 

Property Organization, done at Stockholm, July 14, 1967, and may include other 

subject matter as agreed by the Parties. 

C. Each Party shall ensure, through contracts or other legal means with its own 

participants, if necessary, that the other Party can obtain the rights to intellectual 

property allocated in accordance with this Annex. This Annex does not otherwise 

alter or prejudice the allocation between a Party and its nationals, which shall be 

determined by that Party's laws and practices. 

D. Except as otherwise provided in this Agreement, disputes concerning intellectual 

. property arising under this Agreement shall be resolved through discussions 

between the concerned participating institutions, or, if necessary, the Parties or 

their designees. Upon mutual agreement of the Parties, a dispute shall be

otherwise in writing, the arbitration rules of UNCITRAL shall govern. 

E. Termination or expiration of this Agreement shall not affect rights or obligations 

under this Annex. 

Ill. Allocation of Rights 

A Each Party shall be entitled to a non-exclusive, irrevocable, royalty-free license in 

all countries to translate, reproduce, and publicly distribute scientific and 

technical journal articles, reports, and books directly arising from cooperation 

under this Agreement. All publicly distributed copies of a copyrighted work 

prepared under this provision shall indicate the names of the authors of the work 

unless an author explicitly declines to be named. 

B. Rights to all forms of intellectual property, other than those rights described in 

paragraph III.A above, shall be allocated as follows: 
2 

(1) Visiting researchers shall receive rights, awards, bonuses and royalties in 

accordance with the policies of the host institution. 

(2) (a) Any intellectual property created by persons employed or 

sponsored by one Party under cooperative activities other than 

those covered by paragraph Ill. (B)( 1) shall be owned by that 

Party. Intellectual property created by persons employed or 

sponsored by both Parties shall be jointly owned by the Parties. 

In addition, each creator shall be entitled to awards, bonuses and 

royalties in accordance with the policies of the institution 

employing or sponsoring that person. 

(b) Unless otherwise agreed in an implementing or other 

arrangement, each Party shall have within its territory a right to 

exploit or license intellectual property created in the course of the 

cooperative activities. 

(c) The rights of a Party outside its territory shall be determined by 

mutual agreement considering the relative contributions of the 

Parties and their participants to the cooperative activities, the 

degree of commitment in obtaining legal protection and licensing 

of the intellectual property and such other factors deemed 

appropriate. 

(d) Notwithstanding paragraphs 111.8(2)(a) and (b) above, if either 

Party believes that a particular project is likely to lead to or has led 

to the creation of intellectual property not protected by the laws of 

the other Party, the Parties shall immediately hold discussions to

In the event that information identified in a timely fashion as business-confidential is 

furnished or created under this Agreement, each Party and its participants shall protect 

such information in accordance with applicable laws, regulations, and administrative 

practices. Information may be identified as "business-confidential" if a person having the 

information may derive an economic benefit from it or may obtain a competitive 

advantage over those who do not have it, and the information is not generally known or 

publicly available from other sources, and the owner has not previously made the 

information available without imposing in a timely manner an obligation to keep it 

confidential.
