CONTAINMENT SPRAY PUMP FAILURE TO START REF:
G. W. Reinmuth response dated September 19,1972, to a request for technical assistance by J. G. Keppler The problem of the containment spray pump failure to start was pursued during an R0 Region I inspection at the site on November 9-10, 1972, in accordance with TAB's suggestion (R0 Inspection Report No. 50-219/72-05).
-While the failure was not explained completely, the conclusion reached by our inspectors was similar to TAB's, i.e., the probable cause was a lack of control power to the breaker.
During a followup discussion with the DL project leader, it was learned that DL has contacted the licensee regarding the problem. A technical specification change is under consideration by DL which would require the testing of the core spray system following its return to service after it has been deactivated.
It is concluded that R0 need take no further action on this matter.

i Mr. Giacbusso June 28, 1973 l
The failure of relay 16K22B is thou;ht to have been caused by an internal breakdown of the ccil insulation resulting in an "open" in the coil J
windings.
1 The pump starting failure was traced to a wire which had broken off from the key lock svitch. This broken wire may have contributed to a previous l
failure of containment spray system #2 which was reported by Mr. I. R. Finfrock, l
Jr. in his letter of August 11, 1972 to Mr. A. Giambusso.
The wire failure was j
noted to occur at the break in insulation near the terminal connection.
This l
b2cak was not detectabic in the inspection reported in the referenced letter.
l 1
The circuitry and components associated with relay 16K22B were checked to climinate any external cause for the f ailure. The coil and series resistor on 16K22b were replaced.
In order to check the auton,atic reset capability of the system, the systen tiode sv.' itch was then placed in " dynamic test" and a s'arveil r
lance test initiated.
During this test, the broken rire on the key lock switch was found and reconnected and the mode switch returned to " automatic".
The system returned to a stanCby condition and the relay was verified to be energi:ed.
Further voltage checks were made on the relay and found to be satisfactory.
In each of the tuo above ecset,, the containment spray system could h::ve functioacd normally haJ it been called upoa for ener;ency service.
Follouing the failurer of relay 16l 22B, the system would not have "r:: set" autcc tically if the mod: suitch had Lcen noved out of " automatic" t o o u...e othm uoje.
The eperator, houever, would have been aviare of this fcilere due to the presence of the "disabic tne s, stem uanu:dly.
alaru and cruid have recet s
The failurcs of reley coil 16K22P and the broken key lock switch wire I
were isolated events which de not indiccre the need for any furti.cr action.
Enclosed are forty (40) copies of this report.
