Dear Mr. Hukill:

SUBJECT:

REVISION TO APPENDICES B AND C OF THE THREE MILE ISLAND UNIT 1 EQUIPMENT QUALIFICATION SAFETY EVALUATION Enclosed are revised pages to the THI-l equipment qualification Safety Evaluation Report (SER) forwarded to you tiarch 24, 1981. The revised Appendicer reflect changes in the deficiencies for Foxboro transmitters and include a manufacturers recommended corrective action. The potential deficiencies affecting the transmitters were identified during recent testing by a utility owners group. The revised pages should be substituted for the corresponding original pages in the SER. Your response to our request for additional information identified in Sections 3 and 4 of the SER should also address these deficiencies.

Sincerely,

?

Subject:

Potential Deficiency Affecting Foxboro Transmitters, Model Numbers N-Ell, N-E13 or Ell, E13 with suffix Codes /MCA, /MCA/RRW, or /MCA/RR Gentlemen:

Our records indicate that you have received one or more of the Foxboro model nu=bered transmitters listed above. This letter is to notify you that two deficiencies have been discovered in some of these transmitters which may exist in the units shipped to you. The transmitters in question operate at a signal level of 10-50=A.

Similar model numbered units operating at 4-20mA are not affected.

The first issue involves the possible use of incorrect insulating sleeving en transistor and zener diode lead vires in the amplifier. The second issue, involves the use of a specific vendor's capacitor which is not hermetically -

sealed (although claimed to be so). As a result, the capacitor electrolyte can leak under adverse service conditions, specifically heat and time. The failure mode is a decrease in resistance across the capacitor resulting in electrical leakage. The transmitter operation can be affected by limiting the output to something less than full value which, in time, can degrade to no output at all.

Insulatine Sleeving - Radiation resistant sleeving consisting of a silicone coated glass fiber braid has been substituted by a teflon sleeving in some trans=itters.

Tests have shown that teflon will become brittle and deteriorate with a substantial integrated radiation dose. Foxboro testing has demonstrated l

that the teflon sleeving used in these devices will withstand an integrated dose of 10 cegarads with no noticeable deterioration. Tests to 200 megarads produce i.

the brittle conditions which can result in the teflon flaking from the wires.

Based on these tests, operating plants not expected to exceed an integrated dose of 10 megarads have no potential problem and no action is required.

a Where the integrated dose rate could exceed 10 negarads, then units in service shculd be inspected to deter =ine if the proper insulating material has been used. This can be acco=plished by opening the transmitter in accordance with Foxboro Master Instruction MI 20-145.

The a=plifier cover must be re=oved exposing the a:plifier assembly. At one end of the assembly, a transistor and i

a zener diode are counted in the' base casting which serves as a hea sink. The insulating material in question is a sleeving slipped over the lead sites from these two components. The proper material is white and heavy looking. Positive IOXBORQ l

Subject:

identification can be =ade by inspecting one end of the =aterial to establish that the outer =aterial covers an inner braid. Teflen, if used, vill be a single layer caterial and could be either clear or white.

if i= proper insulation is present, then the corrective action is to replace the-o a=plifier (Foxboro P/N N0148PW). Replace =ent amplifiers can be purchased frc=

your local Foxboro Sales or Service Representatives.

If you prefer to have Foxboro Service Personnel inspect the equip =ent and, if necessary, replace the a=plifier, this can be arranged at standard service rates.

Canacitor - The capacitor degradation problem was discovered over ti=e thr'ough tracking failure situations.

Internal corrective action has been taken to re=ove the vendor involved fro = the gaalified vendor list and to purge all stock of capacitors from this vendor. Degradation of this capacitor is a function of ti=e and service conditions with heat being a pri=ary contributor.

This pheno =enen was observed in recent tests of trans=itters usi=g these capacitors. The capacitor in questica is =anufactured by Cornell-Duebilier and can be specifically identified by a type nu=ber in the for= TX-65-XXXX as well as a =onogra= in a box followed by a date code, e.g.lCDE 0874]

It is assigned Foxboro part nu=ber N0141.M?.

To deter =ine if this capacitor is present requires a visual inspection of the a=plifier which can be acco=plished as described above for the insulating sleeving inspection. The recor= ended ccrrective action should the above described capaciter i

be present is to replace the anplifier (Foxboro P/N N0148PW) although is is possible to replace the capacitor with a Foxboro provided substitute. Use of Foxboro Service personnel to perfor= the inspection and replace =ent, if necessary, can be arranged at standard service rates as described above.

f Due to lack of knowledge of specific application, redundaccy, and the like, Foxboro cannot deter =ine if the NRC reporting require =ents of 10CFR Part 21 are applicable.

This deter =ination is the responsibility of the user and any such reporting would be =ade by them after co=pleting their evaluation of the situation.

If you have any questions regarding the above, please contact the undersigned directly.
