Subject:

Dow Chemical Company- Response to the Request for Additional Information for the renewed license of the TRIGA research reactor. License No. R-108; Docket No. 50-264 Enclosed is the response to phone conference Jan 28, 2011.

Should you have any questions or need additional information, please contact the undersigned at 989-638-6932.

I declare under penalty of perjury that the foregoing is true and correct.

Executed on April 4, 2011 Melinda Krahenbuhl, Ph.D.

Director Dow TRIGA Research Reactor Subscribed and sworn to before me this day of April, 2011 Notary Pub i-c Notary P~b~ounty, Michigan SStaq L, McKeon My Commission Expires: NTARYK UaI.C, B'cCOUNT'Y, MICHIGAN AC *Nl,4ID.. .j- y, MICHIGAN LIVOMYMiS,,  %'*JUNE 28, 2011 cc: Sandeep S.

Response to the questions posed in the phone conference Jan. 28, 2011.

1. Provide a Chain of Command from Reactor to the CEO.

a. Organization Chart all US Citizens with the exception of Andrew Liveris

2. Provide Management Level at which budgetary decision is made and level of dollars.

Global Core R&D 2009 budget was 1.6 billion dollars.

0 Analytical Sciences 2009 budget was 50 million dollars. All budgetary decisions for the reactor are made at the Global Director, R&D level.

Reactor Facility budget projected for 2012 is $810,000.

3. Provide support information for decommissioning estimates.

A. Information from facilities used as a guide to estimate cost of decommissioning the DTRR in 2007. DTRR original estimate is bracketed by 1

other reactors of higher power and more diverse function. The DTRR is conservative for the function and size of the reactor.

Power Footprint/Usage Estimated cost Georgia 5 MW 3 stories $7,140,000 Tech Above ground (2001)

Concrete/steel/BORAL and lead shielding 8,000,000 Heavy water moderator and cooled actual cost Graphite thermal column University of 1.5 MW Prepared for shut down prior to $4,200,000 Illinois decommissioning (2007)

University of 2 MW + 2 reactors on site above ground $6,400,000 Virginia CAVILlER (2003)

University of 2 MW 3 stories $9,800,000 Michigan Above ground (2006)

Concrete/steel/BORAL and lead shielding Graphite thermal column DTRR 300kW Below ground installation no shielding, $5,000,000 no thermal column, no beam ports (2007)

B. Square footage, Power and Usage of the current facilities used for "benchmarking". Our current estimate is above the estimate on a $Slicensed power, indicating our estimate does not need to be adjusted.

Licensed power Estimated cost Purdue 1 kW Converted HEU $623,000 to LEU Penn State 2 MW Beam ports/ $12,000,000 above ground/

MURR 10MW Beam ports/ $49,000,000 above ground/

will use SAFE I Storage DTRR 300kW 1 $5,467,000 2

Decommissioning estimate vs Licensed power 50 30 + Research reactor 40

"*I m0[ DTRR 20 E

E 10 oU0- Linear (Research 0 reactor) 0 5000 10000 15000 Licensed power (kW)

C. Mathematical example will be changed for decommissioning estimate instead of surety bond.

As stated in the Response dated Dec. 7, 2010, "The cost estimate for decommissioning the DTRR will continue to be adjusted annually using the inflation factor as calculated in 4(d) of this response."

The inflation factor is based on the Implicit Price Deflators for Gross National Product (FINAL) which are published in July of each year. Since the decommission cost estimate was calculated prior to the annual GNP being published, the previous 2 and 3 year annual GNP figures published as of July in the previous year were used.

2007 Annual GNP Implicit Price Deflator is 106.215 and 2008 Annual GNP Implicit Price Deflator is 108.486 (as of July 31, 2009) - source is the Bureau of Economic Analysis, National Income and Product Accounts Table - Table 1.1.9. Implicit Price Deflators for Gross Domestic Product.

2010- 108.49 + 106.21 = 1.021 2011- 109.609 108.626 = 1.009 This inflation factor was used to inflate the decommission

$5,354,600 x 1.021 = $5,467,000

$5,467,000 x 1.009 = $5,516,000.
