Page 1 of 2 '1 SPECIAL REPORT-SEISMIC RECORDER INOPERABILITY On September 13, 1990 the~High Pressure Core Spray'(HPCS) Piping triaxial peak accelerograph recorder was undergoing surveillance testing and could not be calibrated;.some internal components were- ,
observed to be damaged. On September' 15,,1990 the triaxial' peak / 1 accelerograph recorder for the "A" Reactor Recirculation: Pump-Motor was removed to facilitate motor removal. The recorder vas bench calibrated in accordance with its surveillance procedure-and ,i portions of the as-found data were found outside of the " allowable :
value". On September 17, 1990 the Reactor Recirculation Piping' '
i Support triaxial response spectrum recorder was being-tested a1d portions of'the as-found data vere found outside of thel"alloveble value". This recoejer also had evidence'of internel damage:to some components. These channels were. declared inoperable, ara the unit antered Technical Specification Action StatementL3.3.7.2, 1 i which, if the channel remains inoperable for moreLthan thirty days, requires that a special report be: submitted to.the Commission within the next 10 days. -The thirty day '11mit' for the -
HPCS Piping recorder was exceeded on October 12,11990 1 -The-thirty day time limit for two' recorders.vas exceeded.on October 15 and 17, 1990, respectively. '
The triaxial peak accelerograph recorders are designed to sense and record low frequency accelerations in three orthogonal l
directions. Three diamond tipped scribers? trace a permanent record on metal plates by a seriesLof sensitive adjustable components.-
The recorders are self contained and-the plates are. easily removed for analysis after a seismic event.. The triaxial response '
spectrum recorder also sense' and records lov frequency accelerations. 1It is composei of three= detector assemblies whichL are identical but have orientations;in lthree.different' planes _
(east-west, north-south, vertical).' The recorder uses reed stylus mechanisms t'o trace: metal plates; 'Each-detector has twelve reeds',
each with its own plate, corresponding toLvarious frequencies..
The plates can be removed cad analyzed for a~ frequency = spectrum after a seismic event. Both types.of recorders ~are passivin e nature and are used for data collection.

'l Attachment 1 PY-CEI/NRR-1248L Page'2 of 2 During troubleshooting, It was determined that some'of the.
internal components of these recorders. vere damaged and misaligned. The damage indicated that the recorders were jarred or stepped on sometime prior to the surveillance tests. This.is l
believed to be due to a large amount of work activity in the _ .
l dryvell area where these three detectors are located atJthe start of the second refuel' outage which' began approximately September 10, 1990. The HPCS' Piping recorder was not-able to be reworked,- -
therefore a replacement unit was procured and calibrated inL
- accordance with its surveillance instruction and_is avaiting.
- l. installation. The."A" Reactor Recirculation Pump ~Hotor recorder' l
only required adjustments t'o internal ~ components and'is.avalting' ;
l installation. The Reactor' Recirculation' Piping Support recorder t was reworked and calibrated successfully-in-accordance withlits: i surveillance instruction and is also avalting installation.-
l These three recorders vere _not. installed:and declared operable _due to continued work activities in the dryvell area which potentially would cause repeated damage to the sensitive recorders.::The HPCS=
Piping and Reactor Recirculation Piping l recorders are:in high traffic and work at as. The "A". Recirculation Pump recorder-cannot be installed until:the motor is' reinstalled."LAll-out-of-service seismological-instruments are expected to be restored within 30 days.
. t Ve do not anticipate these_out-of-service instruments to-significantly degrade our ability to detect /re' cord' seismic motion within the-plant. The Perry Plant is a fully. instrumented '
Regulatory Guide 1.112 facility. Vith these three instruments '
unavailable, we vould still-have severalLinstrumented locations including both a triaxial response spectrum recorder and critical instruments at the Containment baseslab'.,LAt this location a '
strong motion triaxial time-history accelerograph'is:available, with the ability to alarm at the Control' Room.. The-strong motion.
triaxal accelerograph provides a: permanent paper / magnetic record-locally at'the electrical equipment room,.and the triaxial response spectrum recorder provides spectral-information directly, ;
to the Control Room. In the' event of detecting'an earthquake' o
during this refueling time period, we vould have the ability.to adequately record the event and take appropriate action.
