Entergy: Cooling towers not best option for Indian Point

BUCHANAN — The Indian Point nuclear plant is making a pitch to use underwater screens to filter Hudson River water rather than build the $1.5 billion concrete cooling towers the state wants .

  1. Behind-the-scenes political manipulation has put NY State in an awkward position. Andrew Cuomo has been angling to position himself for a run at the governor’s chair for at least the last decade. In order to capture the support of antinuclear groups, who could figure prominently in Democratic primary battles, Cuomo has declared himself personally opposed to Indian Point. After his antinuke declaration, he had his troubleshooter J. Jared Snyder placed into the NYS DEC, to write the famous “Ipec kills fishes” letter, (based on a flawed Riverkeeper brief) which was to be the tip of his political spear for shutting down Entergy’s plant.

    DEC , under Snyder, chose an undoable option…the building of cooling towers…as its faux “recommendation” to Entergy, knowing such monstrous towers would raise an eco-furor of their own, if ever attempted. But by focusing too hard on the effort to shut IPEC, Snyder ignored the ongoing trend to use wedge wire solutions for fish protection. The US EPA has declared wedge wire to be BTA …the Best Technology Available for compliance with the clean water act, and Entergy has joined the long parade of companies who have installed wedge wire.

    Now Entergy has called Snyder’s hand….. if he REALLY cares about fishes, wedge wire is an elegant solution. If , however, he is merely doing Cuomo’s bidding as an antinuke mole inside DEC , he will insist that “Only cooling towers” will suffice, when the entire industry, including EPA, knows better.

    Its the old scripted Kabuki of antinuclear posing, raised to state-agency level.

    To get a feel what wedge wire screens look like, See:




    Indian Point already has traveling screens filtering its intake water,

    but the size of the screen mesh is big enough so that fish eggs or plankton can sift through, and get sucked in. (called entrainment). So even though no fish recognizable as a fish can get sucked in, tiny critters the size of spermatozoa CAN get caught. It was on this factoid that Jared Snyder of NYS DEC made his exaggerated claim that “a billion fish” were being “slaughtered” at Indian Point. Truth is, its more along the lines of a billion microbes….but NOT a billion fish.

    Snyder also claimed that the inward flow of water was fast enough to trap grown fish against the screens. (called impingement). Indian Point uses a backwash spray to clean off the screens, if stuff is on the screen, the intake is blocked…. so if a fish can wait 2 minutes, it gets hosed back into the river unharmed. Anyway, Snyder’s politically motivated claims seemed credible enough to anyone sitting in an office, or anyone predisposed to disliking Indian Point, and there it stood.

    Now we turn to wedge wire. A Wedge wire screen presents a smooth non-sticky surface to the animals, and can be crafted to any gap dimension. If striped bass eggs are .004 inches across, a screen can be made that is .003 inches across, & voila’… all the eggs are saved. The Wedge wire intakes are set off away from the tip of the intake pipes, so water flow at the screen is very gentle, and air bubbles periodically blow anything loose, freeing it to live a long, prosperous fish life in the dank & PCB-filled Hudson. Fish problem solved. Half a dozen other plants along the Hudson use wedge wire, and it is accepted by EPA as BTA. The wedge wire will not replace the existing screens, but will stand out in front of them, giving fish 2 safety barriers.
