- On August 31,1997, during the weekly exercise test of control blade 50-27, when the -
blade was inserted one notch from the full-out position 48 to position 46 and then
- l rsturned to full out, the full-out position indication of 48 was lost. A continuous 4 -withdrawal signal was selected to restore position indhation which resulted in a " rod i overtravel" alarrn, indicating de-coupling of the drive from the control blade. In accordance with existing procedures, power was reduced to below 60%, followed by full insertion of blade 50-27 to position 00 and its being disarmed. Upon subsequent frl, - troubleshocting, the blade _was fully withdrawn (again, without receiving position
~'
' indication for the full-out position of 46) Blade movement was verified during the withdrawal by monitc, ring Lncal Power Range Monitors (LPRMs). The blade was t judged to be coupled since an overtravel alarm was not received following selection of a continuous withdrawal signal after the blade was judged to be fully withdrawn; however, since the full-out position indication of 48 was not received, the blade could
' inot procedurally be' determined to be coupled and was therefore re-inserted fully to n y position 00 and disabled by hydraulic block in accordance with TS requirements.

f ' '(Control Rod Exercise and Control Rod Coupling Check) is to fully withdraw the blade

'9 fully out in order to apply the withd:awal sigrwi to check for overtravel. Since the blade t

1.[The reason fdr operating the blade in the near full-out position of 46 is to minimize the Sp: ! s, TE3ei opersilon of the core and resultant reduction in thermal limit margin that occurs with the subject blade fully inserted. I g '
d hy j m 10 Safety Assessment
-m
{ The primary concern for control rod _ coupling integrity is its impact on the potential
_ increase _in the~ probability of a Control Rod Drop Accident (CRDA) as analyzed in the
' L Shfety Analysis Report (SAR).- Procedural changes include full insertion of the subject blade during reactor operation below 10% rated thermal power, whers the CRDA is a
'~
concern. For occurrence of a CRDA, the drive and control blade must be uncoupled, ithe drive 'must be withdrawn with the control blade otherwise retained in its inserted gg
" . position land then me blade must be subsequently released, falling to the position of
,the drive. Above 10% rated thermal power, the consequences of a CRDA are (negligible, and no restr_ictions on control rod position are required even if the drive and g
blade can not be verified to be coupled.- Therefore, the subject t lade and drive will .
remain fully inserted during any reactor operation below 10% of ' rated thermal power, I Teliminating any consequences from a postulated CRDA.
[ iA secondary concern related to~a potential uncoupling is the inability to ascertain
, control blade position. Since the position indication dispSy is an indication of drive
(;~ _
_position, the indication may not be an accurate reflectiois of blade position if the drive W' '
' land blade are uncoupled. To minimize the effect of this, during blade 50-27 withdrawal Labose reactor thermal power of 10%, neutron flux information in the vicinity of the blade Jwill be' monitored via' Local Power Range Monitors (LPRM) or Traversing In-Core Probe e
. i(TIP) to verify that the blade tracks with drive movement.1 This will ensure the blade is
^
a not sticking and is not separated from the drive.- It is not credible that a withdrawn, uncoupled control blade could be buoyed upward into the reactor core; the velocity limiter at the base of the blade is shrouded by the guide tube and is not subject to lifting force due to core flow.E Cooling flow from the control rod drive pumps averages
, _ approximately 1 gpm per. assembly and is insufficient to overcome the weight of the control blade and velocity limiter.
O l Another concern is potential equipment damage from scram loadings. With the drive in
@"g/ 1s' withdrawn position and the blade not coupled to the drive, following a scram initiation,
~
< the blade could become separated from the drive during the deceleration phase near 1 the top'of the scram stroke. This'woulo allow the blade to centinue traveling upward, f with the velocity limiter impacting the bc ttom of the fuel support casting. This may y" : cause damage to the velocity limiter, and upon rebound, to the' drive spud and blade Elock plug; however, GE has determined that there is insufficient energy to dislodge the 1 fuel support (or tuel) or to cause a threat to the pressure boundary integrity. This poterdial for damage to the velocity limiter and/or spud is not a safety concern: the function ~of the velocity limiter is to control the free-falling speed of a control rod during a CRDA.' The subject rod will not be withdrawn below 10% thermal power where the 4 effects of a CRDA ar;e significant, therefore postulated damage to the velocity limiter 3

v has. no adverse safety consequence. _ Damage to the drive spud or blade lock plug,
- pcardkg their function to couple the drive and blade, is not consequential since they are assumed to be not coupled, and the described mitigating actions assure no adverse effects from the uncoupled condition. The potential for damage to the velocity S L IW and/or spud can be minimized by not scramming under cold depressurized oork,itions, and scram testing, if necessary, from the lowest achievable withdrawn
_ pot} tion.< Scram and insertion performance are not considered to be degraded by 3 # operating with the blade in position 46 since negative reactivity insertion characteristics ' l
- are'slightly improved by starting the scram motion from a slightly inserted position. !
m+ '
g.
- Therefore, it is concluded that operation with the subject control blade withdrawn to a <
near full out position of 46 does not lead to any condition adverse to reactor safety.
