Dear Mr. Kintner:

Reference:

Enrico Fermi Atomic Power Plant, Unit 2 NRC Docket No. 50-341

Subject:

Post Accident Sampling Analytical Procedures We have reviewed the guidance provided in your trans-mittal of March 26, 1982 to assure the suitability of analytical procedures used for post-accident sampling.

Detroit Edison proposes the following analytical program consistent with your request:

1. Boron analysis will be performed by utilizing the HACH carminic acid colormetric method, if boron injection is initiated. Additional testing uti-lizing the standard chemical test matrix supplied in your transmittal will also be performed.
2. Chloride analysis will be performed by an offsite analytical laboratory. The turbidimetric proce-dure for chloride that is described in your transmittal as inappropriate was not proposed or planned for use in post-accident sampling ana-lysis by Detroit Edison.

3 Dissolved oxygen will be verified to be (0.1 ppm by measurement of a positive hydrogen residual greater than 5 cc/Kg, if chloride is >0.15 ppm.

When ALARA considerations permit, oxygen will be measured directly.

4. The pH will be determined by micro pH probe.-

Confirmatory analysis will be performed by an off-site analytical. laboratory. Additional testing is currently being performed to ensure the suitabi-lity of this method.

5 Dissolved hydrogen will be determined by gas'chro-matography. _ Gas chromatography,has been successfully demonstrated for the determination of hydrogen in-the presence of gamma radiation through testing and analysis by Babcock & Wilcox on TMI-2 post-accident gas samples.

In addition, within 270 days of this letter a summary.

of suitably verified procedures will be provided to the Staff. This summary will indicate the equipment and describe the method used to meet the analytical

. requirements for post-accident sampling.

Sincerely, f./
