According to the Seven-Year Plan for the Development of JINR 2010-2016 approved by the Committee of Plenipotentiaries of the Governments of the JINR Member States (CPP) in November of 2009, the DRIBs-III Project included the following:

• According to the Seven-Year Plan for the Development of JINR 2010-2016 approved by the Committee of Plenipotentiaries of the Governments of the JINR Member States (CPP) in November of 2009, the DRIBs-III Project included the following:

• Modernization of the currently operating U400 and U400M accelerators

• Development of new physical experimental setups (separators, etc.)

• Construction of a new Experimental Hall with a total area of 2,500 m2 to carry out experiments with beams of stable and exotic radioactive nuclei.

• Development of a new high-current heavy-ion DC-200 accelerator with the intensity of the average-mass ions (48Cа) no lower than 5∙1013, i.e., around 10µA.

• The Project Financing and Implementation Schedule approved in 2009 is presented in Table 1.

Recently obtained results at the FLNR JINR on synthesis of new superheavy elements (SHE) are highly appreciated, and the FLNR JINR joint research in the specified areas between the FLNR JINR physicists and their longtime collaborators from the US, Germany, France, and Japan is acknowledged. In the course of the project's implementation, the CPP, taking into account the recommendations of PAC and the JINR Scientific Council, proposed:

• Recently obtained results at the FLNR JINR on synthesis of new superheavy elements (SHE) are highly appreciated, and the FLNR JINR joint research in the specified areas between the FLNR JINR physicists and their longtime collaborators from the US, Germany, France, and Japan is acknowledged. In the course of the project's implementation, the CPP, taking into account the recommendations of PAC and the JINR Scientific Council, proposed:

• to achieve the main project objectives while at the same time implement the scientific program on synthesis and investigation of the properties of SHE (earlier, the U400 cyclotron was planned to be shut down for 2-year-long upgrade in August 2010);

• to construct the world's first Superheavy Element Factory (SHE Factory) at JINR, including:

• a new high-current heavy-ion DC-280 accelerator with the beam intensity up to 20 рµА, А≤ 238 (earlier, a DC-200 accelerator with the beam intensity of 10 рµА, А≤ 100, was planned to be constructed);

• a new Experimental Hall with a total area of 5,500 m2 for carrying out experiments with highly radioactive actinide targets in radiochemical laboratories laboratories of second class by the Radiation Safety Standards. Earlier, an Experimental Hall of third class with an area of 2,500 m2 was planned;

to upgrade the existing U400 and U400M accelerators to pursue world-class research and development programs in the three key areas of the heavy-ion physics at low and intermediate energies, in particular: synthesis of new SHE and the investigation of the properties of the already discovered SHE (SHE Factory) that will be carried out at the DC-280 cyclotron; nuclear physics experiments (spectroscopy, fusion-fission of heavy and superheavy nuclei, etc.) performed at the U400 accelerator; experiments with exotic radioactive nuclei (6,8Не, 11Li, etc.) carried out at the U400M accelerator;

• to reconstruct the U400 Experimental Hall housing 6 radiation-shielded caves with a total area of 1,500 m2;

• and

• to construct a new FLNR JINR Experimental Hall (total of 1,500 m2) to conduct scientific research on the application of heavy-ion beams in nanotechnology.

• However, the above-mentioned changes do not seem possible under the Seven-Year Plan for the Development of JINR (2010-2016) without USD 30.1 million in additional DRIBs–III Project funding. Proposals on the adjustments to the DRIBs–III Project Financing and Implementation Schedule are summarized in Table 2.

According to the Project Financing and Implementation Schedule presented in Table 2, the above-mentioned project updates shall be implemented in full (the ultimate goal) over the period from 2013 through 2016.

• According to the Project Financing and Implementation Schedule presented in Table 2, the above-mentioned project updates shall be implemented in full (the ultimate goal) over the period from 2013 through 2016.

• Should difficulties arise in finding additional funds (USD 30.1 million), some of the work will have to be postponed until 2017–2019. The high-priority tasks (the "minimum program"), which shall be fully implemented under the JINR Seven-Year Plan (2010–2016), shall thus include the following:

• Development of the world's first SHE Factory, launch of a new DC-280 accelerator, construction of a new Experimental Hall and experimental setups for synthesis and investigation of the properties of SHE

• Implementation of the scientific program on the SHE synthesis (U400 accelerator)

• Completion of works on the U-400M modernization, and the development of a new ACCULINNA-2 separator for carrying out research on exotic radioactive nuclei

• Completion of preparatory and design works for the renovation of the U400 Experimental Hall and the modernization of the U400 accelerator to ensure the implementation of the above-listed tasks in 2017

• The proposed DRIBs–III Implementation Schedule of the “minimum program” is presented in Table 3.
