In September 1989 the Indonesian government decided to perform a new the NPP’s feasibility study including a comprehensive investigation of the Muria site. The study itself should be carried out by the National Atomic Energy Agency / BATAN under the directives of the Energy Committee (PTE) of the Department of Mines and Energy, and with the cooperation of other institution such as State Electricity Enterprise (PLN).

On August 23, 1991, an agreement was signed in Jakarta between the Indonesian Ministry of Finance and BATAN on behalf of Indonesian government, and the consultancy company NEWJEC Inc. (Japan). This agreement contracts NEWJEC Inc. for a four and a half year period to perform a site selection and evaluation, as well as a comprehensive NPP’s Feasibility Study.

The scope of the feasibility study includes two main components :

• The non-site studies, covering energy demand and supply, energy economy and financing, technology and safety aspects, the fuel cycle and waste management, and general management aspects, among other things.

• Site and environmental studies, covering field investigation and assessment of candidate sites, site qualification and evaluation, and environmental, socio­economic and socio-cultural impacts.

On December 30, 1993, the Feasibility Study Report (FSR), also called Non-site Study Report (FSR), was submitted. A final report including a site and environmental report, and a preliminary safety analysis report will be provided at the end of the four and a half year contract. These documents will provide the information necessary for site permit application, for the design engineering basis and other project and industrial infrastructure preparations.

Safety aspects are of utmost concern in the FSR, which cover and assess not only the proven designs available in the market at present, but also advanced systems expected to enter the market in the near future.

The main results of the FSR are among others Primary Energy Supply Scenario shown on Table 1.

Coal fired plants will dominate the electricity generation system. Nuclear Power Plants will increase in accordance with the demand. The data from this scope of work are used for optimization studies in the development of the Java-Bali electric system. The optimization shows that the first NPP’s operation is feasible in the year 2004. In the year 2019 the share of NPPs will give a contribution of 10% of the electricity supply, am amount equal to about 12,600 MW.
