9 Twin Orchard Drive Oswego, NY 13126 April 22, 2011 Mr. Bill Borchardt Executive Director for Operations U.S. Nuclear Regulatory Commission Washington, DC 20555-0001

Dear Executive Director for Operations Bill Borchardt:

This is a performance-based 2.206 request letter.

I request a fine of $500,000 of the Salem Unit I plant operator for failing to have an effective corrective action program that fixes problems promptly. A current example is their (continuing) inability to remove sufficient Delaware-River carried vegetation (from the water drawn in for their condensers) before a plant scram is necessary.

The event is Event Number 46774. I have also enclosed a letter reporting this problem dated April 27, 2007 and another letter dated May 1, 2007.

Thankou, u,-)

Tom Grzed Member, ASME (Has anyone in the organization proposed variable speed circulating pump motors so flow to the condensers can be reduced to what their intake screens can handle? Of course, this would also require a reduction in reactor power.)

Dear Mr. Ralph Izzo:

I believe I have identified a repeating problem with the circulating water system at your Salem plants. Simply put, the current design is not adequate to provide for reliable electric generation. (For instance, Salem Unit 1 had to be manually tripped on April 24, 2007 due to problems with this system.)

I am writing this letter to suggest four ways you can provide the plants with reliable circulating water.

1- Use natural draft cooling towers. Hope Creek would provide an example.

2- Use forced draft cooling towers. I understand they are cheaper to build but more expensive to run than the natural draft type. The Ocean States combined cycle power plant in Rhode Island used them.

3- Use a cooling lake. I have been told that they are in use at Dresden, LaSalle and Braidwood.

4- Use spray headers and canals. I have been told that Dresden also has these.

Notice that you would control the water in these structures and thus electric generation would not be at the mercy of river grass movement, as is now the case.

There seems to be two ways to go: either spend the money and save the scrams, or, save the money and take the scrams.

Thank you, Tom Gurdziel

Dear Mr. Samuel Collins:

Recent events at Saleml have caught my eye. While I feel that an entire system change is necessary for a reliable circulating water system, (perhaps to mechanical draft cooling towers), here are a few ideas that I hope you see offered and considered by the Artificial Island people as temporary mitigating solutions:

Spray Wash subsystem Bigger pumps, bigger pipes, and bigger/higher pressure flow through spray nozzles Different pattern spray nozzles An additional set of spray nozzles at a different orientation Possible use of intermittent (or manual) compressed air Manual use of fire hoses Trash Screen subsystem Run continuously at highest speed when river grass is near Try different types of screen openings Increase the highest operating speed Trash Rack subsystem Do they help or hurt river grass removal? (Would you be better off without them?)

Circulating water pump motors Change to variable speed so you can demand a lower water flow (at a corresponding lower reactor power). This may reduce the load on the screens and sprays.

External Consider using chemical treatments to kill the growing grass. (Probably needs state permits as a minimum.)

Consider wood piles/nets to change the flow path of river grass before it gets into the plant Harvest the grass while it is still in the river Determine if heated circulating water exiting the plant is increasing the growth rate of the river grass and making the problem worse Thank you, Tom Gurdziel
