Alldiscrepanciesfound(whenconsideredonanindividualbasis)appearnon-significant in respect to satisfactory operation of the valve. All problem bolted connections were at least 75% of specified torque.

At least one bolt was checked with a torque wrench on each bolted connection.

If the use of hand tools was required on the other bolts, the torqued bolt was loosened with a hand wrench and then retightened to the same position to give the workman an accurate sense of the anount of force required to properly

tiShten the bolts.with hand tools. 'Ihis procedure is en improvement over the one outlined in the original inspection program.

SPECIFIC DISCREPANCIES FOUlTD ON MOTOR OPERATED VALVES Y0EE/301DTEP BOLTDIG:

1E12-F009 1 of the h bolts was found to be marginally under the lowest allowable torque value for proper bolt preload*;

ho ft-lbs. instead of 50 ft-lbs. specified. This equals 95% of the lowest allowable torque value for the total i

bolted connection.

value based on a previously determined vrench accuracy within +5%

1E51-F063 1 of the h bolts was found to be hand tight. This equals 795 of the specifled torque value for the total bolted connection.

OPE 5tATOR/ YOKE BOLTDiG:

l 1B21-F005 1 of the h bolts was found to be hand tight. This equals 75% of the specified torque value for the total bolted connection.

1 of the li bolts was found to be hand tight. This 1Bf1-F016 equals 796 of the specified torque value for the total bolted connection.

ESSD:TIAL OPEKATOR ASSEMBLY BOLTDIG:

.TIGHTITESS DISPECTION RESULTS (Page #2),

MAIN STEAM ISOLATION VALVES All actuator bolts were visually inspected to essure they were tight against their lockwashers. lio discrepancies were found.

t All tie-rod nuts were checked for proper torque. No discrepancies were found.

MADT STEAM RELIEP VALVES The bonnet and actuator bolt locking devices were inspected on all 18 valves. Discrepancies with locking devices were found in the following L

(all associated bolting was found to be tightened to the proper areas:

torquevalue) ir cylinder tie-rod nut tab washers were bent out of the position (averageof2to3washersoutof8on12 valves) proper 1.

Solenoid valve mounting bolt tab washers were positioned improperly 2.

(cverage of 2 to 3 wachers out of 12 on 16 valves).

On 6 of the 18 valves the tamper seal cable was detached on the 3

threaded plug that covers the relief pressure adjustment screw.

The adjust =ent screws were inspected and found undisturbed.

On one valve 2 lockwires were found damaged on the bonnet / body bolting.

i 14 All of the above discrepancies were resolved under the direction of the Crosby Valve Company service representative.

REACTOR RECIRC FLOW C011 TROL VALVES All actuator bolt locking devices were inspected. Three pairs of actuator' position indicator nounting bolts were missing lockwires on the 1B33-F060A valve.

These lockwires have been replaced.

In additica to the bolt locking device inspection outlined in the original progran, essential yoke to bonnet bolting and actuator rod coupling bolting were inspected to torque valves specified in the vendor instruction manual.

I!o discrepancies were found.

Mr. Warren' Vanle:

Subject:

LaSalle County Station Unit l' Structural Bolting Tightness Inspection Results for Containment Valves I'have reviewed tne subject document which you telecopied to.me on July 9, 1982.

I concur with the disposition and assessment ybu nave i

made in that report.

This concurrence is based on the work that was done to develop tne information transmitted in Sargent & Lundy's June 28, 1982 i

letter.

Altnough they are clearly undesirable, none of the items l

identified in your transmittal if left uncorrected.would have presented a i

safety' problem.

In tne case of tne connection with one hand tight bolt, we believe that the required load would be carried.

This statement is based is carried w.en the' bolt is in place.

The on the fact tnat tne load e

torque values on tne rem'aining bolts would maintain the proper contact on the mating surfaces.

With respect to the locking devices not being properly placed, we again believe the load would De carried since the Dolts were properly torqued.

The locking devices provide additional assurance that the bolted connect,Will riot turn and tnen loosen.

.Your corrective action to restore the bolting to our specified requirements constitutes adequate corrective action.

l, LASALLE COUNTY STATION UNIT 1 STRUCTURAL BOLTING TIGHTNESS INSPECTION PROGRAM FOR CONTAINMENT VALVES SCOPE This inspection program will be limited to safety-related valves inside Containment
~
and will consist of the inspection (and correction if required) of:
1.
proper tightness, or 2.
proper installation and condition of bolt locking devices-(whererequired).
for valve structural bolting essential for the valve ' function relative to sa'fe plant l
shutdown and containment isolation.
Valve pressure boundary (bonnet and packing gland) bolting is not included in this' inspection program.
The containment valves involved in this inspection program are separated by valve function as follows:
1.
Manual 2.
Motor Operated 3.
Air Operated 4.
Testable Check 5.
Main Steam Isolation 6.
Main Steam Relief 7.
Reactor Recirc. Flow Control For the valves included in this. inspection program, mounting hardware for external valve position indicator switches will be visually inspected to assure bolting is loose bolts will be noted on the tight against lockwashers or mounting bracket; inspection form and tightened with ordinary hand tools.
(
I.
GUIDELINES FOR BOLT TIGHTNESS INSPECTION Manufacturer's recomendations will be used for spec. torque value. Where a manufacturer recommends " wrench tight", the following target torque values should be verified:
BOLT DIAM. (in.)
TARGET TORQUE (ft-1bs.)
11 5/16 47 1/2 5/8 94 3/4 167 7/8 270 1 1/4 808
(
Reference:
6/28/82 B. F. Pandit letter Attachment "A", Page 2, for i 15% torque wrench accuracy.)
Above target torque values are for ASTM A193 B-7 material.
If " wrench tight" is specified for a different bolt material, CECO. Project Construction Engineer will request applicable values from CECO. Project Engineering'and document this infor-mation on the inspection form.
Limitorque operator mounting bolt torque should be verified in accordance with the above requirements or the following values, whichever is less:

MANUAL VALVES Valve yoke / bonnet bolting for. manual valves is only safety significant for valves none are located inside required to be closed for primary containment isolation; All manual valves in containment are provided for maintenance or containment.
A yoke failure on these valves would only allow the' disc to back seat test purposes.
and cause no significant problem. Therefore, inspection of the operator structural bolting 'will not be required.
INSPECTION DOCUMENTATION:
none MOTOR OPERATED VALVES (24 valves total)
The following motor operated valve structural bolting will be inspected for tightness:
1.
yoke / bonnet bolting 2.
operator / yoke bolting

operator assembly bolting essential to the function of the motor 3.
operator assembly - visual inspection to assure bolting is tight against lockwashers; loose bolts will be noted on the inspection form and tightened with ordinary hand tools.

INSPECTION DOCUMENTATION:
none I
MAIN STEAM ISOLATION VALVES (4 valves total)
All actuator bolts have lockwashers, with the exception of hydraulic cylinder tie-rod nuts. The actuator bolts will be visually inspected to assure they are tight against their lockwashers. The tie-rod nu't torque will be checked in accordance with instruction manual requirements.
INSPECTION DOCUMENTATION:
FORM i MSIV MAIN STEAM RELIEF VALVES (18 valves total)
All bonnet & actuator bolting (including air cylinder bolting & solenoid valve' The actuator mounting bolts) are either lockwired in pairs or have tab washers.
arm bolts have lockwashers. All of these bolt locking devices will be inspected to assure they are installed, installed properly, and are not damaged. This Bolt inspection will be directed by the valve manufacturer's representative.
tightness will be checked as directed by the manufacturer's representative, for All other only those bolts with missing or improperly installed locking hardware.
bolts with locking hardware installed in acceptable condition can be assumed to be factory tight since the valves have not been subjected to operating vibration loads.
