Dear Sir or Madam:

Qual'f<lch NP ts prnvid.ing this notificmim, as a potemia! 10 CFR Part 21 issue. The TVA Browns Feny Plant notified us of two sepua.t.i, RCSll)resser n,:tuator foilur1:s which we had provided as safety rcfated c,>1n1l<lt1cnts. According to TVA the first failure ,,ccurred ()[! Fcbniary 7, 2022, atier bdl'lg installed for uppmximalely I 67 days. The 2nd failure occurred on Febnwry 9, 2(}22 an,I was in s,*rvic<' for appro,,imately 24 lwurs whlm it failed.

1.0 INTRODUCTION

Tl1e purpose of this reprn1 is lo documem the results of a Failure Evaluation involving two Curtiss-Wright (CW) supplkd RCS/Dresser l'N: SURE-24-10-4 actuators per TVA email/correspondence dated 2/11/2022 and 3/912022. 'I11ese units were originally qualified under HOS Report.s EGS-TR-927700-48 Rev. C and EGS--TR--927700--47 Rev. It Failure I: The CW supplied Actuator was identi.lied as Ta11, # CJ 18 .I l Hll; Serial Number 02.

The item !u.1s a 1111111ulcteturer's sed:il number of 712787()602. *n1e Actuator was (1ri~Jnally dedicated by Curliss--Wrighr for TVA agains\ their Purchiise Order II 7140421 Rev.I, imd originally shipped ()11 Fcbrum:y 81h, 20:1.2 umfor C ufC #CJ! 8111. I.

According to *rv A personnel the Actuator's motor brake foiled within 24 hmm, of op,m11ion.

  • n1ey noted the heat shrink tubing had a lmni mark and removed it  !() fiod 1h1.11 the surface lll()l.llllcd li.lse was Mown an() the wire insulation lmd exposed wiring where wiring wr,s atta~hcd 10 the f.h1rm: via a tie wmp. The it~,111 was then rel urned to Curtiss-Wright for evaluation urn.ler RA-CC l 0711 *I. Sec TV A pmvidcd l)ll()!os in Attachment A.

Failwc 2: Th<:: CW supplied Actuator wa, iden!ilit:d as Tag ii CJ 1703401; Serial Number 02.

The item has a numufacturnr's serial number (Jf 7003810902. *n1e A.:tual()I' was originally dedicated by Cm1iss-Wrighl for 'lVA agai11st their Purchase Order# 1,5271.29 Rev.I, and originally ship1it*d 011 l/22/2021 under C ofC # CJ 17034.1, According to TVA personnel the A,,tuator was installed on 8/24/2021 and failed in scrvk,e on 2/7/2022, (~xperiencing the same type failure as the fir~I failed unit, that being frayed wire insulation in the Actuator's brake assembly rcisulting in an electrical shon, 'I'he item was then returned to Cmt.iss*Wdght for evahwtiou uoder RA-CC968.l-1.

2.0 CURTJsa.WRIGHT FINDINGS Upon receipl of thi: rnturncd Actuators, Curl:iss-Wrighl performed a visuul inspc(,tion which co11Hm1ed wire d,m1age. The wiring had two issues:

04/07/22 14:01:45 8553056216 -> Fax Seruer Margie Bauer Page 010 CURTISS- Report No. CJ18111.FE WRIGHT Revision 2 l) Wires were tension tight to a metal edge instead of having slack as shown in TVA phol()S,

2) Wires were loc,ited next to a cut edge ofthe metal. It is pem1issable to tie adjacent to a bent edge m* a flat surfa,x~, but not wil*(:, touching a ,:,.ut edg,: or 11 h<.11,: thut 1,,,,,

not been countersunk or otherwis-, dclmrred.

Ro()f c.,nise oftht, failure is friclfon between wire insulation & the sharp meti1llic edge that cut through th,i i11su.lution vii, vibm!fon which in tum sh()rtcd the power leads to the frmne. The bk,wn fi.1sc was a sec()ndary failme to the insulation failure iii the wire bundle alfo<:led.

Dise!l$sioo with t.he OEM indic:;ted th:11 the current SURE 24 model has been in production since the 1970's. The only thing that has changed is the brake assembly, which l11l! been in pr(,lduction since the I990's. The OE.YI stated that c11mplaints of !his type arc -1xtrcmely rare and 11()! a co1m111,11 iss11e, CW ,ales history includes two sak,s from our Huntsville office (total qty (>f 11) g.ohig bnck to Febmary 2010, and two sales from our Cincinnati office (total qty of

3:JO RESOLUTION arid CONCLUSION The leads mu~\ be pathed in such ,i way ,is to !lV()id cut/sheared edges without being able to touch or itm:rforc with moving parts. If s1.1d1 a pa.th .is not l)()Ssible, then the wires will rcquim additional protection such 11s a fiberglass sleeve or wire mesh sleeve to protect the insulalion from abrasion.
