Matters discussed and comments, on the part of the management personnel, were as follows:
<
December 23, 1975
,
i 1.
The inspector stated that the inspection had been scheduled to review the reactor internal fit up procedures and observe the trial fitup of the reactor internals.
Due to conditions
>
and problems encountered with the Polar Crane and documented by TECO the inspection of the reactor internals trial fitup was not possible.
He further indicated that he had i
reviewed NCR 870 that had been issued on the Polar Crane indicating that the main hook had not been NDE examined as required by ANSI-B30.2 requirements.,. The inspector added that due to the fact that neither TECO or their contractors, Babcock and Wilcox or Bentley, had documented approved pro-cedures to cover the inspection testing and certification of lif ting equipment as required by 10 CFR, Part 50, Appendix B, Criterion V, an infraction in regard to this item would be issued.
Since the use of the equipment had been curtailed an NCR issued and procedures preparation was in progress the inspector stated that no reply to this item would be required.
(Report Details, Paragraph 2)
The licensee stated that the entire matter would be further reviewed and that steps had been taken to generate the l
necessary procedures to prevent this condition from reocurring.
2.
The inspector stated that he had also been informed and had been shown documentation that the stop-work order issued to
,
Bagwell had been lifted. He further added that during a
'
subsequent inspection IE:IIT. inspectors would examine Q painted areas previously coated within containment.
3.
The inspector stated that an unresolved item would be generated as a result of the inspection. This item pertains to review of the results of th'c MT examination of the main polar crane book.

1.
The inspector stated that this inspection h' d been'rcscheduled a
to observe the trial fitup of the reactor internals and to resolve the probicms encountered during the December 22-23, 1975, inspection, lic further stated, that his observation of the lif ting of the reactor internals from the reactor vessel appeared to be in accordance with B&W approved trial fit up
!
l procedure No. 151.
,
!
2.
The inspector stated that he had reviewed the draf t of the i
station Polar Crane operation, testing and maintenance proce-
!
dures. He further indicated that the procedure did not include, f
in the inspection and maintenance section, inspection require-i ments of Chapter 2-2 of ANSI B30.2.0-1967. The licensee stated
that they would review this item.
3.
The inspector stated that the cleanliness of the reactor pool j
and reactor vessel had improved since the last inspection, and that necessary precautions should be taken to insure the cicanli-ness of the Reactor Vessel internals during the cleaning and painting of the containment vessel.

Results of Inspection
- l.
Reactor Vessel Cleanliness Inspection December 22-23, 1975 The inspectors reviewed Babcock and Wilcox Field Construction Procedure No. 156, Revision 0, Approved 12-8-75, Titled " Clean reactor vessels." During the visual inspection the inspectors
noted that the vessel had not been made ready for trial fitup of the reactor internals, scaf folding, cables, and other items were still in place in the vessel.
Inspection January 5-6, 1976 The inspector observed the cleanliness of the reactor pool and
-
reactor vessel, noting that improvements had been made to maintain the area in the required class "B" cleanliness level.

Polar Crane Test and Inspection
,
Inspec tion-Dec ember 22-23, 1975
.
The incpectors requested documentary evidence that the Polar Crane had been inspected prior to a trial fitup of the reactor internals.
Monthly visual inspection records were available and reviewed.
llowever, no records were available to indicate that the crane had been inspected and tested as required by ANSI B30.2.0-1967, Chapccr 2-2, " Inspection Testing and Ibintenance of Cverhead and Gantry Cranes."
In addition, there were no instructions available to control the inspection of the crane.
On December 12, 1975, a Nonconformance Report No. 870 was generated indicating that the hooks of the Polar Crane had not received a magnetic particle inspection since Fbrch 3, 1972. As a result of
'
the NCR,. the 180 Ten polar crane hook S/N 8E770-P1 was magnetic particle tested. The test en December 22, 1975, showed that indications detected in the hook during an earlier inspection were still present in the 6" diameter hole however, evaluations of the test results had not been completed.
'
,
l Original record s in "Redock packet" - No. 93 indicated that the material of the polar crane hook had not received a physical test
'
)
when manufactured, however, a nonconformance report was generated, an engineering evaluation made, and the heck was accepted.
Other s/m i
original test results were'found to be in order.
I Inspection Januarv 5-6, 1976
'
The inspectors reviewed a nonconformance report (No. 881) issued on December 29, 1975, as a result of further evaluation of the MT indications in the eye of hook SIN 8E770-Pl. Also revicued were reports of a inspection of the Polar Crane performed by llarneschfeger Corporation on December 30, 1975, certifying the crane for use.
The Polar Crane hook and block assembly was removed and replaced with the 190 ton assembly from the Turbine Building Crane. The hook of
,
,
this assembly was MT inspected Ly Testmaster.
The MT report indicated i
that this hook was acceptable for use. The hook and bloch assembly
removed from the Polar Crane is being returned to the llarneschfcger Corporation for repair or replacement.
