Indian Point 2 and 3, 1982, Indian Point Probabilistic Safety Study, Consolidated Edison and NY Power Authority. 

The review of the data portion of the Indian Point 2 (IP2) and 3 (IPS) PRA (a 1982 internal document prepared by Consolidated Edison and the New York Power Authority) is confined to the plant-specific and generic component failure and service hour data sections because these were the only segments available to the reviewers. The LERs produced during a ten-year span of IP2 s operation were evaluated to determine their applicability to the PRA data needs. It was eventually decided to use only the LERs generated after IP2 became critical (from May 23, 1973 to December 31, 1979) for the component data base development, based on the availability of failure event information and more uniform operability, testing, and reporting criteria. 

Hot water can be transported over longer distances with little heat loss while steam heat distribution systems can only serve high-density regions. The largest steam system in the United States is a part of New York s Consolidated Edison Company and serves a small part of Manhattan Island. The larger pipes or mains carry 200 to 250°F water under pressure. Re-...

Consolidated Edison Company of New York installed a simitar -I K MW unir in New York. City, but after a lew years, the project was closed down. The demonstration did mu see the production of power as planned because the acid electrolyte of the fuel celts became depleted due to emended program delays. An attempt to replenish the aid was unsuccessful However, must was teamed daring the engineering, licensing, construction ami start-up phases of ihe program.

In the fall of 1978 a full-scale test program was pursued in a commercial power plant of the Consolidated Edison Company in New York City (4). The test was conducted in three phases in Con Edison s 74th street station utilizing a 450,000 lb/hr steam electric Combustion Engineering tangentially-fired boiler, as shown in Table V. 

The Consolidated Edison test results, as shown in Table VI, indicated complete suitability of SRC-II coal liquids as a high quality boiler fuel. No operational problems were encountered and no deposits were observed. Combustion efficiency was comparable to that for the low-sulfur No. 6 fuel oil, as were the levels of carbon monoxide and hydrocarbon emissions. Modifications to burner equipment required to handle the SRC-II fuel oil are considered to be no more extensive than those required for similar variations in petroleum fuels. Particulate emissions for the SRC-II fuel oil were generally lower than for the No. 6 fuel oil, and were in all cases below the new source performance standards proposed by EPA (0.03 lbs/MM Btu). 

PANELIST SCHMID The material burned at Consolidated Edison was a blend of what T referred to earlier in the paper as middle distillate and heavy distillate. We find that the ratios of these two do vary considerably with different coals and different operating conditions. We made a blend with a ratio of what we felt would be representative of the material we would produce in a commercial plant. As we studied the process further, we could see that there would be some cases in which this might vary and there might be a little more of the heavy distillate to middle distillate. But the test fuel may well be representative of exactly what we would make. This is still subject to some further study and firming up of the design. 

Consolidated Edison Co. announced on January 12, 1979 that it will seek federal approval to replace up to 10 million barrels of imported oil per year with domestic natural gas as a fuel in its electric power and steam plants. 

Recently, a completely new approach to the design of HTSR furnaces was placed in pilot plant operation based on process and mechanical design developments by United Technologies Corporation (UTC). This new reformer will be part of the fuels processing system in an electric power installation designed to produce 4.8 MW for the Consolidated Edison Company in... 

The first large-scale privately-financed nuclear power plant is being built by Consolidated Edison Company of New York. It is also the first thorium power plant in the world. The site of this 55,000,000 station, with a capacity of 200,000 kilowatts, is Indian Point, New York, on the Hudson River about 40 mil s north of New York City. This water-moderated breeder type of nuclear system will supply electricity to about one million New Yorkers starting in 1960. 

In the molten carbonate process a molten eutectic mixture of lithium, sodium, and potassium carbonates removes sulfur oxides from power plant stack gases. The resulting molten solution of alkali metal sulfites, sulfates, and unreacted car bonate is regenerated in a two-step process to the alkali carbonate for recycling. Hydrogen sulfide, which is evolved in the regeneration step, is converted to sulfur in a conventional Claus plant. A 10 MW pilot plant of the process has been constructed at the Consolidated Edison Arthur KiU Station on Staten Island, and startup is underway. 

The pilot plant, funded by Consolidated Edison, Northeast Utilities, and Rockwell International, will process a side stream of stack gases from a 335 MW boiler at the Consolidated Edison Arthur Kill Station on Staten Island. It is planned to vary the SO2 concentration at the inlet to the scrubber in order to map process performance over a range of conditions. The side stream will correspond to approximately 10 MW equivalent of gas. 

Due to a thunderstorm upstate, four separate power lines were struck by lightning earlier this evening. Within half an hour the utility suffered a massive loss of some 2,000 megawatts. At precisely 9 34 p.m., New York City experienced a total electrical blackout. As the Consolidated Edison Company struggles to restore power to the city, reports of widespread violence and looting have been flooding in. 

In February 1977, as PC-19 began churning out electricity, the US Department of Energy, in cooperation with the Electric Power Research Institute, issued a request for proposals to build a big (4.5 megawatts) phosphoric acid demonstrator fuel cell power plant in New York City. Consolidated Edison was picked as the host utility. 

To simulate recovery of uranium and thorium from irradiated 6 percent uranium, 94 percent thorium fuel from the first loading of Consolidated Edison Company s Indian Point 1 nuclear power plant, Oak Ridge National Laboratory [R3] made small-scale experiments on application of the acid Thorex process to fuel containing the appropriate amounts of uranium and thorium, with tracer quantities of the principal fission products. Spent uranium-thorium fuel from the Indian Point 1 plant was subsequently processed by Nuclear Fuel Services, Inc., at West Valley, New York, for recovery of uranium, but without separation of thorium from fission products. No account of this separation has been published.

A second PWR was designed and built at Buchanan, New York, for the Consolidated Edison Company. The reactor was designed by the Babcock Wilcox Company and had the unique feature of an oil- or coal-fired superheater. The plant was a 275-MWe and 585-MWt plant. The plant used fuel that was a mixture of uranium and thorium oxide.
