Thank you for sharing.

Wouldn't have been possible to share without you and what you've accomplished here.

Thanks Bill.  Looking forward to reading it.

Advice for revision of this book would be more than welcome.

Advice for revision of this book would be more than welcome.

You should revise the section on Watts Bar unit 2 as TVA is in the process of completing construction and they are back to working towards completing Bellefonte.

Will do...thankyou.

What is between the sub pile room floor and the metal bottom of the drywell in a Mk 1 BWR?

A statement in the comment section of an ancient survey of the anteroom at the end of the tunnel to beneath the stack at bldg 771 at Rocky Flats said "My God, it's full of stars."

It wasn't.

In the case of Fukishima there is 7.6m of concrete:

If uncooled, could melted fuel exit the reactor building by passing through the torus, torus room wall and then the reactor building wall?

I just saw this thread, not sure how I missed it before.

What about Peach Bottom Unit 1 experimental high temp gas cooled reactor?

I have admired the quality of your posts.

The book started as a Commercial Nuclear Power Plant Contract RP study guide many years ago.

I was then asked about the design differences relative to RP job coverage; B&W vs Westinghouse steam generators...Mk 1 vs Mk 3 reactor buildings, drywells and refuel floors...etc.

I was then asked how all this came about.
 
So the book is limited to operating American Nuclear Power Plants, 10 CFR 20 / NRC Radiation Protection and a brief history of the origins and progression of the existing light water plants.

It is intended to be the simple introduction to the industry that I wish I had been provided with when I started.

I believe it is unique and serves a much needed purpose.

I enjoyed reading the beautiful bronze plaque in the breezeway outside the training building commemorating Peach Bottom 1.

Gotcha! Very well done indeed!

"The melted core material did not even get close to exiting the container that was designed to retain it. And this was a case where the reactor was operating at full power and then lost all cooling within a few minutes. It is hard to get much worse than that."

"...in the worst case that TEPCO is describing, by its own data, the core material may have melted only about as much as 5% of the distance to the grade."

Fukashima 1 is a BWR 3 in a Mk 1 Rx Bldg.

The only US plants of this design are Quad Cities 1&2, Dresden 1&2, Pilgrim and Monticello.

If uncooled, could melted fuel exit the reactor building by passing through the torus, torus room wall and then the reactor building wall?

You may be able to get fission products in the torus, but fuel would have a hard time getting there.  The bottom of the drywell catches anything that might melt through the reactor vessel.  After that, the last line of defense is the concrete structure the plant is built on.  This saved Fukushima from the "China Syndrome".   

"The melted core material did not even get close to exiting the container that was designed to retain it. And this was a case where the reactor was operating at full power and then lost all cooling within a few minutes. It is hard to get much worse than that."

"...in the worst case that TEPCO is describing, by its own data, the core material may have melted only about as much as 5% of the distance to the grade."

Interesting choice of words here.  The container designed to hold the "melted material" is the reactor pressure vessel.  That failed as well as the drywell- the "containment". 

Tepco's data is updated infrequently and they have yet to provide conservative estimates of the damage.  It's always the same:  "we were so lucky xyz didn't happen."  Tell that to the thousands that may never return to their homes.

Don't BWR 3's have a mix of isolation condensers and RCIC?

Had the IC stayed in use, unit 1 likely would have been the least damaged unit.  It would have been quite easy for a fire truck to keep up with the evaporation rate.

 "For about 1 hour after the earthquake and the loss of offsite electrical power, the emergency diesel generators (EDGs) were operating and providing electrical power to the systems for decay heat removal. At about that time, the tsunami struck the site and the EDGs stopped working. This was likely due to the failure of the fuel supply to the EDGs. With the loss of the EDGs, cooling to the fuel in the core was being provided by the reactor core isolation cooling (RCIC) system.
The RCIC system uses steam generated in the reactor from the decay heat to power a turbine driven pump. The pump is supplied with water initially from a condensate storage tank (CST). The water for the CST is injected into the core through the feedwater line. Once the CST is drained, the suction of the RCIC pump is switched to the suppression pool where there is another large source of water. It appears that this system provided decay heat removal for about 7 hours after the reactors where shutdown following the earthquake. Typically, electrical power for the motor operated valves is provided by onsite batteries."

How would/does the isolation condenser in bwr 2s & 3s work. Is it direct vent to outside?

Yep, they have a large vent to the roof of the reactor building. 

[Laundry Man]

Or as in the case of Oyster Creek, they exit the side of the building facing Route 9.

I was asked by Mike what happened to the website, "American Nuclear Power Plants" where my book of the same title is located.
