subject as above.

B. ~ Telephone conversation between Walt lhaas, USNRCL and ted Taylor, Hatch, Inc. on November 2, 1989.

Dear Mr. Murley:

In response to Reference-A above, the following information,keyed to' Referenced 10CFR21 Report is furnished:

H 4* 1. -Self: explanatory2. - Self explanatory-.

3. ' Hatch Incorporated acknowledges;that it did build the- six Instrument Racks in response to NPPD Purchase

Instead it was agreed by telephone that NPPD would perform fa leak test upon arrival at NPPD and correct any leaks at that :

time. Based upon this phone call, Hatch, Inc. did not pneumati-i

cally test the Instrument Racks nor wrench tighten the fittings i

without. benefit of a subsequent leak test. The-fittings were ;

shipped in a finger tight condition only. See Enclosure 2. |

If these Instrument Racks had been installed in a "as. received condition" contrary to enclosure 2, then Nebraska ;

JPublic Power Division must assume all liability for'any safetyhazard related to.the use-of the six (6) Instrument Racks furn-ished by Hatch, Inc. -In addition, since these Racks were-

*shipped on October 2, 1986 and no deficiencies were reporteduntil November 1, 1989, a period in excess of three years and ;two years past the one year warranty period, it can only beassumed that NPPD did not honor the agreement to perform the

.

5

leak test upon receipt of the equipment, therefore no further :

action is deemed appropriate, by Hatch Incorporated. ;)5. November 6, 1989 - When referenced letter was received

at Hatch Incorporated. !

6. Hatch Incorporated did not manufacture any InstrumentRacks other than the six in question.

7. Self explanatory -

8. No communication of any type prior to receipt on i

November 6, 1989 of reference above, has transpiredbetween Nebraska Public Power District and Hatch .

-Incorporated.

Please note-that a Hatch certified test report covering the,

six Instrument Racks has never been issued. This is because i

John Hubl at Nebraska Public Power District assumed this respon- '

:sibility. In addition, since so much time has elapsed sincedelivery of.the racks and-there is no way for Hatch Incorporatedto.know what kind of conditions the racks were stored in, we can- '

not assume liability for any defects after expiration of thewarranty.

Very truly yours,
