Dear Mr. Schwencer:
Attached are draft changes to FSAR 3ection 9.1.5.5.5 and Table 9.1-12 which were discussed in the referenced p
telecon concerning reactor enclosure crane performance testing.
The information contained on these draft FSAR changes will be incorporated into the FSAR, exactly as it appears on the attachments, in the reviaion scheduled for June, 1984.
Sincerely, Eug.e J B a ley JHA/gra/050984850 Attachment cc:

O the following procedure:
A dimensional check of the hook is
(
i performed and the dimensions recorded.
The hook is then proof-tested at 200% of its rated capacity.
After the test, the hook is given a magnetic particle examination, and its dimensions are rechecked and recorded.
The hook is accepted.if no cracks, t
permanent deformation, or other defects are produced by the testing.
l l
9.1.5.5.4 Ropes-Samples.are taken from,each wire rope to,be used in the crane and are subjected to.. destructive breaking strength tests to verify l
that the rope exceeds the manufacturer's published value for
. breaking strength.
At least two'such tests are performed on each j
3 rope.
9.1.5.5.5 ' Performance and Acceptance Tests l
Af ter erection of the crane in the reactor enclosure, extensive j
. performance and acceptance testing is carried out, including:
3 a.
Detailed checking of all mechanical and electrical components of the crane to verify proper assembly and j
operation j
b.
Running-in tests at no load.
This test includes all
(
speeds and motions for which the crane is designed plus t
verification of the proper operation of all limit
'e switches.
i c.
Load testing at 125% of the rated capacity.
This test l
includes the full range of movement for hoist raising and lowering and bridge and trolley travel.
l l
)
d.
Performance testing at 100% of the rated capacity.
This test includes all speeds and motions f'or which the crane t
is designed, plus verification of the.oroper operation of all, limit switches.[&rbrbc.e. tesSn3 a+ len h 1007 Icf l

Position C.1.a.
The load lifts during construction were riot greater than those for plant' operation, therefore no separate specifications were prepared.
(2)
Position C.1.b(1).
Box girders are not of a closed design.
i (3)
Position C.1.b(3).
The. crane manufacturer did not perform impact testing on any structural members.
(*)
Position C.1.b(4).
Not applicable - no ASTM A 514 is used.

L component failures.
Fu r t.h ermo re, such testing violates t.he ANSI Standard B30.2 and Title 29 CFR, Part 1910.179(k).
A non-destructive examination (NDE) following the cold proof test is performed on-10% of each critical weld.
Cold proof testing every 40 months, followed by NDE, will not be performed since the crane operating temperature will not be less than 600F.
(27) According to the implementation Section D.2 of the guide, the quality assurance discussion of Paragraph C.5 is not applied to cranes ordered before September, 1976.
Although the Limerick crane was ordered in August, 1973, a quality assurance program was required of the vendor.
- However, this program could not and did not address the recommendations of Paragraphs C.1 - C.4 as suggested in D q aph C.S.b of the guide.
