India should sell off shore nuclear reactor to de salinate water for Singapore needs.
Line up a bunch of old soviet style nuclear submarines ( make sure that they don't submerse)
And supply the hot team into heat exchangers to de salinate

The official said the program to dismantle nuclear submarines from the Northern Fleet had almost been completed and the majority of vessels due to be scrapped are currently with the Pacific Fleet
This decommissioned missile cruiser has a reactor of 300 MWt

. Desalination is energy-intensive. Reverse Osmosis needs up to 6 kWh of electricity per cubic metre of water (depending on its original salt content), hence 1 MWe will produce about 4000 to 6000 m3 per day from seawater. MSF and MED require heat at 70-130°C and use 25-200 kWh/m³, though a newer version of MED (MED-MVC) is reported at 10 kWh/m3 and competitive with RO. A variety of low-temperature and waste heat sources may be used, including solar energy, so the above kilowatt-hour figures are not properly comparable. For brackish water and reclamation of municipal wastewater RO requires only about 1 kWh/m3. The choice of process generally depends on the relative economic values of fresh water and particular fuels, and whether cogeneration is a possibility.
Some 10% of Israel's water is desalinated, and one large RO plant provides water at 50 cents per cubic metre. Malta gets two thirds of its potable water from RO. Singapore in 2005 commissioned a large RO plant supplying 136,000 m³/day - 10% of needs, at 49 cents US per cubic metre. Malta gets two thirds of its potable water from RO, and this takes 4% of its electricity supply. Singapore in 2005 commissioned a large RO seawater desal plant supplying 136,000 m3/day - 10% of needs, at 49 cents US per cubic metre, and has contracted for a 318,500 m3/d RO plant on a build-own-operate basis, costing US$ 700 million, to provide water at US 36 c/m3. The same company is building a 500,000 m3/d seawater desal plant in Algeria.
The UAE operates the 820,000 m3/day Jebel Ali MSF plant in Dubai, Fujairah producing 492,000 m3/day, Umm Al Nar 394,000 m3/day, and Taweelah A1 power and desal plant producing 385,000 m3/day.
In February 2012 China's State Council announced that it aimed to have 2.2 to 2.6 million m3/day seawater desalination capacity operating by 2015.
Small and medium sized nuclear reactors are suitable for desalination, often with cogeneration of electricity using low-pressure steam from the turbine and hot seawater feed from the final cooling system. The main opportunities for nuclear plants have been identified as the 80-100,000 m³/day and 200-500,000 m³/day ranges.
A 2006 IAEA report based on country case studies showed that costs would be in the range ($US) 50 to 94 cents/m3 for RO, 60 to 96 c/m3 for MED and $1.18 to 1.48/m3 for MSF processes, with marked economies of scale. Nuclear power was very competitive at today's gas and oil prices. A French study for Tunisia compared four nuclear power options with combined cycle gas turbine and found that nuclear desalination costs were about half those of the gas plant for MED technology and about one third less for RO. With all energy sources, desalination costs with RO were lower than MED costs.
The Kwinana desalination plant near Perth, Western Australia, has been running since early 2007 and produces about 140,000 m3/day (45 GL/yr) of potable water, requiring 24 MWe of power for this, hence 576,000 kWh/day, hence 4.1 kWh/m3 overall, and about 3.7 kWh/m3 across the membranes. The plant has pre-treatment, then 12 seawater RO trains with capacity of 160,000 m3/day which feed six secondary trains producing 144,000 m3/day of water with 50 mg/L total dissolved solids. The cost is estimated at A$ 1.20/m3. Discharge flow is about 7% salt. Future WA desalination plants will have more sophisticated pre-treatment to increase efficiency. In August 2011 the state government decided to double the size of its new Southern Water Desal Plant at Binningup plant near Perth to 100 GL/yr, taking the cost to about $1.45 billion. Stage 1 of 50 GL/yr was within the A$ 955 million budget.
At the April 2010 Global Water Summit in Paris, the prospect of desalination plants being co-located with nuclear power plants was supported by leading international water experts.
