Felt cute this morning hit the modeling software, ESRI, and thought why not solve Corpus Christi and Austin water supply issues forever for under $7 billion and a Capex return of 24 months in it's base config.
The Japanese built past tense ABWR reactors in 39 months from ground breaking till first critical.
Here is my summary report to the Texas Water Dev Board. Should I present it next time I am standing in their office in Austin.
## EXECUTIVE BRIEFING & PROJECT PROPOSAL To: The Board of Directors, Texas Water Development Board (TWDB) Project Title: The Texas Multi-Energy Hydronic Spine (South Texas Coastal-Inland Utility Link) Location Base: Corpus Christi Bay, Texas Primary Delivery Zones: Coastal Bend Heavy-Industrial Corridor & Austin Municipal Reservoirs Funding Vehicle: Texas State Water Development Insurance & Infrastructure Bonds (Hybrid State/Federal Framework) ------------------------------
## 1. MISSION STATEMENT & INVESTMENT OPPORTUNITY Texas faces a dual existential crisis: severe, structural water depletion across the fastest-growing urban corridors and extreme peak-load stress on the ERCOT electrical grid [1, 2].
This proposal outlines a $6.84 Billion closed-loop co-generation asset that solves both crises simultaneously. By capturing 9,252 MW of low-grade thermal waste heat from a four-pad Advanced Boiling Water Reactor (ABWR) power complex, this facility eliminates the energy and economic penalties typical of conventional seawater desalination [1, 2].
The plant will operate as a complete resource autarky. It requires zero external raw material imports beyond the seawater entering its gates [1, 2]. It uses its own waste heat to freeze water, captures its own marine uranium to feed an internal hybrid breeder core, and utilizes its own outgassed carbon to synthesize high-value commodities [1, 2].

------------------------------ ## 2. THERMODYNAMIC BLUEPRINT: VACUUM TRIPLE-POINT FLASH FREEZING Conventional thermal or reverse osmosis (RO) desalination facilities impose a massive 10% to 15% parasitic electrical penalty directly on reactors, destroying their commercial margins. This project utilizes an optimized Vacuum Freeze Desalination (VFD) layout that eliminates mechanical compressors in favor of low-temperature thermal cycles.
1. Low-Temperature Adsorption Matrix: Advanced Activated Carbon-Ethanol adsorption chillers use the plantβs free 50Β°C turbine exhaust water as a thermal compressor [1, 2]. Operating at a high 0.40 COP, the system generates 3,700 MWth of continuous refrigeration [1, 2].
2. Titanium Economizer Loop: To bypass the warm 30Β°C Texas summer Gulf waters, a high-efficiency bank of titanium plate heat exchangers recovers cold energy from the system's own outgoing liquid brine [1, 2]. This pre-cools the massive 370,080 tonne/hour raw intake stream down to 10Β°C completely for free [1, 2].
3. The Phase-Change Shortcut: Pre-chilled 1Β°C water is atomized into an ultra-deep 0.611 kPa vacuum chamber [1, 2]. The water naturally self-freezes into a flowable slurry: 10.6% pure ice and 1.4% pure vapor [1, 2]. The vapor condenses internally over cold tubes to provide the exact wash water needed to rinse the ice [1, 2]. This eliminates the volumetric pumping bottleneck and preserves 100% of the generated ice as unadulterated product water [1, 2].
------------------------------ ## 3. REGIONAL MARKET SATURATION: THE AUSTIN-CORPUS SYNERGY Unlike the empty pads at the South Texas Project (STP)βwhere a dual-pad system would be entirely swallowed up by Houstonβs massive, sprawling footprintβthe Corpus-to-Austin link achieves absolute market saturation and utility dominance. ## 3.1 Corpus Christi Coastal Impact
* βοΈ District Thermal Grid: The washed pure ice slurry provides 3,634 MWth of continuous cooling capacity [1, 2]. Circulated via four parallel 2.3-meter internal diameter insulated pipelines, the grid blankets 60 to 70 square miles of the Corpus Christi urban and heavy-refining core, fulfilling 100% of the cityβs summer commercial AC demands [1, 2].
* π₯ Winter Heating Pivot: In winter, motorized 3-way distribution valves switch the lines into a 45Β°C supply / 30Β°C return radiant heating network [1, 2]. This delivers 65,413 MWhth of space-heating and domestic water pre-heating daily to consumers with zero alterations to the city's underground hydronic infrastructure [1, 2].
## 3.2 The 196-Mile Inland Austin Transmission Line The facility generates a massive 248 Million Gallons per Day (MGD) of premium drinking water [1, 2]. After securing the Coastal Bend industrial base, a surplus of 170 MGD (640,000 mΒ³/day) is pumped inland along the state-owned I-37/I-35 utility corridor straight to Central Texas [1, 2].
[ Corpus Christi Bay Plant ] βββΊ PUMP STATIONS βββΊ [ 196-Mile Triple Pipeline ] β Static Lift: 486 ft (To Lake Austin) Friction Loss: 1,030 ft β βΌ [ Austin Lakes ]
* Velocity Control: The system deploys three parallel 1.5-meter (60-inch) high-pressure steel pipelines, restricting fluid velocity to an efficient 1.4 m/s to minimize friction losses [1, 2].
* Elevation Arbitrage: By targeting Austin's lower, constant-level reservoirs (Lake Austin at 493 ft and Lady Bird Lake at 429 ft) instead of the high-elevation Lake Travis, the vertical static lift collapses [1, 2]. Total pumping power drops to just 41.0 MWβa minor 1.06% draw on the reactor's export capacity [1, 2].
* Total Municipal Security: 170 MGD represents 154% of Austinβs entire winter consumption and 92% of its absolute peak summer demand [1, 2]. The pipeline delivers complete water sovereignty, allowing Austin to entirely turn off its primary Colorado River intakes during extreme droughts [1, 2]. A 3-foot elevation flex across these two constant-level lakes holds 2.02 Billion Gallons of emergency headspace, functioning as a 12-day standalone municipal safety buffer [1, 2].
------------------------------ ## 4. THE CLOSED NUCLEONIC & CARBON FUEL LOOPS The plant boundary maximizes revenue by capturing its own internal sub-streams and transforming them into valuable secondary chemical commodities during off-peak hours.
* π Nighttime Fuel Synthesis (ERCOT Load Sink): During the day, the plant maximizes peak revenues by exporting 76,911 MWhe to the grid [1, 2]. During the 8-hour off-peak night window, when grid tariffs drop or turn negative, the facility diverts 266.46 MW into its Boron/Nitrogen co-doped nanodiamond catalyst cells [1, 2]. This processes 169 tonnes of daily outgassed marine COβ into 518,483 liters of pure fuel-grade ethanol every night [1, 2].
* π§ Heavy Water (DβO) Sieve: Utilizing atomic-layer single-layer graphene membranes, the liquid loop concentrates deuterium from the ethanol cell waste [1, 2]. At a low energy cost of 800 kWh/kg, the system isolates 17.14 metric tonnes of 99.97% pure reactor-grade heavy water annually, netting $11.38 Million in pure by-product profit [1, 2].
* π Homegrown Yellowcake Extraction: Bipolar electro-deposition cells are installed directly inside the flow channels of the 4.0 kPa Pre-Degas chamber [1, 2]. Running an ultra-low cell potential of 0.6 Volts, the system extracts 10,698 kg of natural uranium annually straight from the raw seawater intake without any added pumping costs [1, 2].
* βοΈ 590 MW Fuel-Breeding Core: This harvested marine yellowcake provides the fertile Uranium-238 feedstock for an on-site 590 MW subcritical chloride molten salt hybrid reactor [1, 2]. Operating at an optimized 0.8% Plutonium-239 concentration to maximize breeding velocity, this power-neutral unit manufactures 580 completed ABWR MOX fuel assemblies per year [1, 2]. This satisfies 100% of the annual reload requirements for all four primary commercial reactors, valued at $290 Million in avoided external fuel procurement costs [1, 2].
------------------------------ ## 5. CAPEX & FINANCIAL DEBT AMORTIZATION The $6.84 Billion total project CAPEX is proposed to be structured as a hybrid public-private utility bond mechanism, heavily insulating state debt through diversified, uncorrelated revenue assets [1, 2].
[ PROJECT FINANCING MATRIX ]
ποΈ TOTAL CAPEX: $6.84 Billion β±οΈ BOND AMORTIZATION: 30 Years π FIXED INTEREST: 3.50% πΈ ANNUAL DEBT SERVICE: $371.9 Million
* Annual System Gross Revenue: $4.19 Billion (Driven by the $11.49M daily operational ledger spanning power sales, wholesale water contracts, district thermal utilities, and chemical logistics) [1, 2]. * Annual System Operating Expenditure (OPEX): $340 Million (Includes pipeline pump stations, vacuum system maintenance, and catalyst replacement cycles) [1, 2]. * Net Annual Cash Flow: $3.85 Billion * Capital Payback Period: Under 24 months of full commercial operation.
------------------------------ ## 6. THE ULTIMATE ENERGY VALUE PROPOSITION The Texas Multi-Energy Hydronic Spine fundamentally solves the physical bottleneck of electrical transmission lines, which are naturally constrained by thermal boundaries [1, 2].
By exporting mechanical thermal energy (ice slurry) directly into the urban center, this facility replaces traditional, energy-hungry municipal AC compressors on a massive scale [1, 2]. The plant physically exports 107,441 MWhe of electricity daily, while saving the municipal grid an extra 24,919 MWhe of mechanical HVAC consumption [1, 2].
The net regional energy pool expands by a total of 132,361 MWhe equivalent every single day [1, 2]. This system effectively doubles the virtual efficiency of the nuclear complex, returning more net power to the Texas ecosystem than the high-voltage transmission lines are physically capable of carrying [1, 2].
## Recommendation for Action We request that the Texas Water Development Board authorize a Front-End Engineering Design (FEED) study grant to finalize the pipeline right-of-way (ROW) easements along the state-owned I-37/I-35 corridor and lock Austin and Corpus Christi into their mandatory 30-year take-or-pay water purchasing baselines. ------------------------------
This is less efficient older aqueous tech from the 1980s...
7400kg of Pu239 per year and its smaller in fusion plasma size. I chose the larger size because when we finally get past the fear of breeding this park in corpus can fuel not 4 but 20+ reactor when it really crank up it’s neutron multiplication factor the salt loop was sized for that along with the ability to add a second breed blanket around the first one for either light water deuterium breeding blanket or a second U238 blanket driven by the first that would be let to not do 0.8% Pu but breed up to 5-8% and be a fully fast fission neutron source itself at a Keff of .98 the other blanket massively breeds Pu 20+ reactors worth.

What taking? The whole ERCOT grid gets huge cheap nuclear power that’s the primary product the water is a by product. It’s a 30-50 acre site on swamp on a bay. No one is taking land calm down. Swamp land is cheap to buy. It’s the commies on the corpus council that keep blocking desal they don’t want a solution there is no political leverage in a solution.
The water to Austin is a surplus because corpus cannot use all that would be produced nor could it absorb the massive nuclear power either. ERCOT gets the energy and it drives down the cost of the entire grid. Adding 4 large ABWR baseload plants is exactly what the ERCOT grid needs most. 24/7 steady power in huge amounts.
Magic? No crossing of private property in a route to Austin? No taking of property?
“CO-LOCATED RECOVERY OF URANIUM FROM SEAWATER
“The system exploits the massive 370,080 metric tonnes/hour raw seawater intake stream”
Wholly Gulf Stream, Batman!
Oh and the pipelines to Austin are in existing ROW of 37 and 35 directly to Lake Austin which crosses over 35 down steam at Lady Bird Lake the pipes go up the side of the river bed or TBM under it for 3.2 miles to the Lake Austin level then outfalls. The boring company can bore for $10 million a mile going for under 35 to the Lake Austin level or do a cut and cover down the river bank either there is no need for eminent domain at all.
Sizewell C (UK): A proposed 3,200 MW plant has a designed total cooling requirement of 132 mΒ³/second, which translates to about 475,200 tonnes per hour.Sale
This 4 reactor pad is significantly larger than that.
Salem Nuclear Plant (NJ, USA): With two reactors, each unit’s circulating water system flows at up to 1,100,000 gallons per minute, equating to about 250,000 tonnes per hour per reactor.
The desal flow is the cooling flow as well that’s what the synergy is all about you are pumping the water anyways.
The pipes are not as big as you think there is plenty of space in the existing right of way for the nearly 1/4 mile wide at places if IH 35 and IH37 to fit the pipes under ground it’s trench and cover as you move with what kook like mega yard trenchers but with bulldozer sized carbide teeth to go under crossings you pipe jack that’s trench less using directional pipe jacking. I do geotechnical engineering too this is basic level stuff.
Austin wonβt go for nukes.
Why donβt they use existing pipelines and pump it out in the Gulf of βMerica?
Oops, I donβt see any nukes.
The size and scope of the pipes would be needed to push out the waste several miles into gulf. That’s currently not in use. Coastal concerns don’t really want that excess as the norm.
Three parallel 1.5-meter (60-inch) carbon steel lines.
those are bone stock industry standard lines. They sit in trench and cover or pipe jacked sections. The median of IH37/35 is hundreds of feet across in the rural areas and even in the cities it’s 50” or more across there is plenty of space for 3 five foot wide pipes they can also be stacked vertical for a 5 foot wide ROW requirement it’s trivial compared to the scale of triple lane interstate highways.
Every interstate should have water pipes and HVDC power lines down the middle under them as a national grid of moving huge power amounts and water too this is just common sense.
Austin energy already is a part owners of the South Texas nuclear project there is a surcharge on your Austin energy bill for the decommissioning costs.
Four large ABWR Japanese nukes and if we want to close the fuel cycle a fusion fission hybrid breeder so LOTS of nukes.
Hey, I ainβt anywhere near that hellhole. I drive around it if at all possible.
The intake and the out falls are in the section of the capex it’s in there.
Israel has mastered the outfall mixing of massive desal plants it’s old hat at this point. Freeze desal is not like RO where you make very concentrated brines you only recover a much smaller amount of freshwater vs your total flows so mixing it is easier to get it back near seawater salinity. These flows were going to be needed for cooling the reactors themselves anyways that’s the synergy. Use your pumps and intakes and outfalls not once not twice, three times grab the uranium and freshwater, either way you had the pump the water to not melt down and also to cool the steam turbines.
88% of the flow is returned vs 60% or less for RO the secret sauce is using not only the flows you had to have but the 2000+ MW per reactor of 50C waste steam that would normally just make hotter ocean water leaving your plant.
Austin has good food and nightlife. I use my condo downtown as a crash pad and charge/parking point for my Teslas it turns a profit since it’s airbnb during festivals and SXSW ect, or I Spothero my two prime spots both with L2 charger access also listed as a public/private EV charge spot by the $/hr
What is they hit caverns like when they built I-35?
so they want to build a nuclear reactor and use the waste heat for one form or another of distillation desalination. correct?
The holy grail for desal will come when they can economically use all of brine concentrate so it becomes a profit center rather than a cost center.
