Licensee Action on Previous Enforcement Matters a.
(Closed) Deviation 50-424/86-56-01, 50-425/86-25-01:
Failure to Revise FSAR as Committed.
Amendment No. 25 to Figure 9.4.1-2, Sheets 1 and 3 of 3, was issued on September 19, 1986, revising the FSAR as committed by the licensee.
Additionally, responsible engineering personnel have been reinstructed in the project procedures governing FSAR change
.
.
controls and in ensuring that commitments made in response to USNRC concerns are concurred with by other affected organizations.
The inspector has no further questions regarding this matter.
b.
(Closed) Unresolved Item 50-424/86-129-01, 50-425/86-59-01:
" Visual Activity Examiner Qualification."
This item was initiated as a result of the licensee being unable to provide objective quality evidence supporting the qualification of certain licensee personnel to admin-ister visual acuity examinations to NDE examiners. This inspector has reviewed a memo written by the licensee's Corporate NDT Administrator which indicated that as of April 1980, all examiners were trained and/or qualified and endorsed to administer eye examinations.
The inspector has no further questions regarding this matter.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort Construction Progress The inspector conducted a general inspection of Unit 2 containment, auxiliary buildings, fabrication areas, and material storage areas to observe construction progress and construction activities such as welding,
.
material handling and control, housekeeping and storage.
Within the areas examined, no violations or deviations were identified.
6.
Construction Nondestructive Examination (NDE) Unit 2 The inspector reviewed procedures, conducted examinations, observed examinations, and reviewed records for various NDE methods, as indicated in the following sub-paragraphs, to determine whether NDE activities were being accomplished in accordance with the applicable code and regulatory requirements.
The applicable code is the American Society of Mechanical Engineers Boiler and Pressure Vessel (ASME B&PV) Code,Section III,1977 Edition, Winter 1977 Addenda.
The nondestructive examinations were being conducted by Pullman Power Products (PPP), Nuclear Installation Services Company (NISCO), and Pullman /Kenith-Fortson (P/K-F) for the licensee.

Inspector Followup Items (IFI) (92701B)
'
l (Closed)IFI 50-424/86-59-15:
" Heat Trace" - This item identified activated but not installed heat trace cables adjacent to the Unit I containment personnel hatch and adjacent to air handling unit A-1542-N7-001-000.
The
,
licensee investigated the identified problem and has determined that in both
!
areas of the subject finding, temporary heat sources-were removed from electrical items upon completion of the required Construction Maintenance Program.and just prior to or during respective system walkdowns.
The temporary heat tape was apparently not immediately removed from the respec-tive areas, and was punchlisted for subsequent removal.
The inspector
has no further questions regarding this matter.
