Background
During the Vermont Yankee 2007 refueling outage, in.accordance with the Vermont Yankee.VT-VMW -2:04 V0:
- Rev 2 Procedure, the Steam Dryer-was inspected. The dryer inspection ipoluded inspection of the Steam. Dryer interior welds and components. These. inspections were.done with GEhs.Fire:Fly RQV with color camera. During the inspecttion of the H1B.V04 weld.(Dryer Unit Hood:End Panel to HB-PL3 Plate weld), relevant linear indications; were
- observed."in the heat affected zone on the Dryer Unit side.of the weld. Most of these linear indications.were: previously seen in.0R-25, Reference INF # 002. When.comparing this.outage with last outage, one. new relevant indication is:
%seen (3T" indication) of% similar appearance, orientation.and size as those previously: seen; one indication :was not seen:
(RF025: 3th.indication). Nodiscerniblech*ange was noted in.those indications which correlates to those of RF026.

Evaluation of Steam Dryer Indication Introduction During RF026 steam dryer visual inspections, flaw indications were reported in the dryer end plates for the internal vane assemblies. Most of these indications were previously identified in RFO2.5 and were evaluated by GE as beihg acceptable to. leave as is per Reference 11. The intent of this paper is to evaluateone new indication identified during RF026 and determine whether it should be: accepted as is.
Discussion One new indication was found adjacent to weld HB-V04, located on bank B at the 0' end and: is labeled. as the 3 rd indication on: INR-IVVI-VYR26-07-10 Rev. I (Reference 2).<
This indicationris of similar appearance, orientation and size as those previously seen.
Because of this it is being treated similar to those indications identified in RF025.. The remainder of indications: on the steam dryer listed as: References 1-10 were previously identified and show no signs of growth, These indications are acceptable to leave as is per GE evaluation GENE-0000-0047-2767 (Reference 11) performed in RF025.
Therefore, the one new indication described above.iS the only one requiring an evaluation.
It should be mentioned that not: all. indications identified in RF025 were re-identified in RF026. The reasons for this vary, but can be the limitations of the equipment, crud layers masking the surface of the indication or the technique of different examiners.
Evaluation of Indications GE's evaluation in RFO25 cites IGSCC as being the likely cause of most of the:
indications previously observed. This.is based. on the jagged appearance and location in the Weld heat affected zone (HAZ). The unit end plates may have cold work resulting from. cold forming. Cold working Type. 304 material can promote initiation of stress corrosion cracks when exposed to the BWR environment. The dryerunit end plates are
- located in the dryer interior and'are not subjected to any direct main steam line. acoustic loading. Continued growth is unlikely because all of -these indications appear to have
.stopped without propagating intothe vertical. weld; this is indicative of IGSCC behavior as opposed to fatigue, since weld material is more resistant to IGSCC. The flanges have experienced a near infinite number of fluctuating load cycles and if fatigue. driven, more significant cracking is likely to have occurred after many years of operation. IGSCC in steam dryers has been. typically limited indepth and length since in many cases it is caused by cold work or weld induced residual stress.
The dyer unit end plate, with the indication, is. securely attached and.captured within the structure of the steam dryer bank assembly, The vertical edges of these end plates are attached to the dryer assembly with 3/16" fillet welds, each weld approximately 48" long.
There were no relevant indications reported in these vertical welds. The geometric configuration of the unit end plates is such that the steam dryer assembly mechanically captures the upper and lower edges. The reported horizontal indications were seen in the inlet side end plate flange. The vanes prevent inspection of the central end plate surface, but inspection of the outlet side end plate flanges at both locations found no indications.
If itis postulated that the end plate horizontal indications propagate across the entire 8.75" unit end plate width including both the inlet and outlet side flange, such full width, through-thickness cracks would have no structural impact, Nor is there any concern for loose parts. The separated end plate sections are still attached and will continue to function.
Safety The steam dryer assembly has no safety function. See BWRVIP-06A for additional discussion of steam dryer assembly safety, The flaw indications reported in the steam dryer INR's from RF026 will not likely result in any lost parts at operating conditions.
Therefore, there is no safety concern with continued operation with the Reference 1-10 indications left as is.
Conclusions and Recommendations The dryer unit end plates flaw assessment is based on the followingfactors: (1) it is a highly redundant structure and there is no structural consequence of the cracking and (2) postulated significant flaw extension leading to the flaw reaching the full section of the channel geometry would not create the opportunity for loose parts. Field experience supports this as-is operation decision in the context that the indications will be re-inspected at the next outage. It is recommended, that the new visual indication given in Reference 2 be accepted as is. Repair is not recommended.

The plant can start up with the dryer indications left as is. The new dryer indication is of the same appearance, orientation and size as those previously observed. Since this new indication is located in the heat affected zone and is consistant with the other indications, this is most likely caused by IGSCC. This is consistant with the evaluations by GE.
