One of the exclusion

factors of the NPP site

is several phenomena due

to the volcanic Hazard.

West Kalimantan is one

area that has almost no

threat of volcanoes, such

as lahar flow, lava flow,

pyroclassic current, new

vent, debris avalanche,

tsunami, etc.

No. Potential Site Challenges

1 Kec. Salatiga, Sambas Close to river delta with high sedimentation rate

2 Pantai Simping, Singkawang Within a tourism area

3 Tanjung Batubelah, Singkawang Close to coal-fired plant complex, both existing and under construction

4 Tanjung Suak, Bengkayang Close to high populated and tourism area, relatively far from existing grid

5 Pantai Gosong, Bengkayang Cooling water intake location > 1 km, high sedimentation rate

6 Pulau Temaju, Mempawah Close to conservation island and Kijing Port (under construction), relatively

far from existing grid

7 Pulau Kumbang, Kayong utara Located between two river deltas with high sedimentation rate and relatively

far from existing grid

8 Muara Pawan, Ketapang Located in alluvial area and relatively far from existing grid

9 Pagar Mentimun, Ketapang Far from existing grid

Gosong Beach• Morphology:

• Gently sloping coastal area facing west, surrounded by hills and local plantations

• Land-use:

• Coastal area, relatively far from dense population

• Closest distance to populated area is 700 m

• Distance from main road is 1.5 km

Lithology and Site Potential

25

• Lithology:

• Hills in the nearby area is composed of volcanic rock, dark gray, porfiroafanitik (mikrogabro-andesitporfiri), fissures in the direction of Northeast-Southwest and Northwest-Southwest. Base-rock is covered by coastal sandy and clayey sediment with high rate sedimentation

• Site Potential:

• Locations near Gosong Beach or Gosong Peninsula is considered as NPP site because it is far from population, good basement condition (granitic). Challenges: distance for cooling water intake and/or outlet > 1 km.

Resources Map of Radioactive Minerals in Indonesia

• SPECULATIVE RESOURCES AREA (SRA) IS THE SELECTED AREA BASED ON EXTRAPOLATION OF SECONDARY DATA

• INDICATED RESOURCES AREA (IRA) IS SRA COMPLETED BY GEOLOGICAL SINTHESYS RESULT FROM FIELD STUDY SHOWING POSITIVE INDICATION SUCH AS RADIOMETRY OR GEOCHEMICAL ANOMALY AND INDICATION OF MINERALIZATION

• POTENTIAL RESOURCES AREA (PRA) IS IRA COMPLETED BY EXTENTION OF MINERALIZATION BOTH SURFACE AND SUBSURFACE AND EVEN KNOWLEDGE ABOUT RESOURCES ESTIMATION

THE URANIUM EXPLORATION DISCOVERED THE RESOURCES AREAS CLASSIFIED AS SPECULATIVE, INDICATED AND POTENTIAL OF RADIOACTIVE MINERALS

CLOSING

27

• Based on preliminary identification of the potential for natural external hazards, in West Kalimantan there are no potential of external natural hazards that could threaten the safety of nuclear power plants

• West Kalimantan has several potential site options that can be utilized for the long term

• Locations near Gosong Beach or Gosong Peninsula is considered as NPP site because it is far from population, good basement condition (granitic). Challenges: distance for cooling water intake and/or outlet > 1 km.
