-
Ultrasonic examination of non-regenerative letdown heat exchanger weld number 1 and weld number 2
-
Ultrasonic examination of non-regenerative letdown heat exchanger bolts 1 through 4 inclusive
>

Section XI of the ASME Code,1974 Edition, Table IWC-2600
'
requires volumetric examination of circumferential butt welds in pressure vessels.- Amendment number 22 to the Beaver Valley Unit 1 license grants relief from the volumetric examination requirement for those welds in the seal water heat exchanger.
The license amendment requires that the shell to flange weld and the head to shell weld in the heat exchanger be examined by visual and surface examination methods.
The visual examination of the flexure attachments in the reactor vessel was monitored by the use of a television receiver and the results were recorded on video tape to establish a permanent record of the inspection.
No items of noncompliance or deviations were identified.
b.
Review of personnel Certification Records The inspector reviewed the qualification and certification-i records of the Virginia Corporation of Richmond personnel who performed the examinations listed in paragraph 2a.
The review was done to ascartain that the individuals were properly qualified ir. accordance with applicable requirements.
In addition to the above, the inspector requested to examine the qualification and certification records of the NDE Level III individual responsible for certifying the Level I and Level II personnel.
The requested records were unavailable at the time of this inspection and the inspector stated that the item would be considered unresolved pending availability and
,
NRC review of the necessary records (334/80-07-01).
c.
ISI Data Review The inspector reviewed data related to the following welds and
_
components to ascertain compliance with the requirements of
the facility technical specification,10 CFR 50.55a(g) and the 1974 Edition of the ASME B&PV Code,Section XI including the Summer 1975 Addenda:

The following parameters were considered when reviewing the above mentioned data:
The method, technique and extent of examination comply
.
with the ISI program The recording, evaluation and disposition of findings are
.
in compliance with the applicable NDE procedure and the ASME Section XI Code The examination method is in accordance with the ISI
.
program Findings were properly dispositioned and reinspected
.
after defect removal (if applicable)
The review of the closure head welds 1, 2, 3 and 4 disclosed the following unresolved item:
The ultrasonic data sheet associated with the above mentioned closure head welds stated that a partial examination was per-formed on the welds.
Reasons for not performing a complete examination were not documented.
The licensee is presently requesting this information from the ISI contractor. This item is considered unresolved (334/80-07-02).
No items of noncompliance were identified.
