Dear. Sir:

HOPE CREEK GENERATING STATION DOCKET NO. 50-354 UNIT NO. 1 On: August 5, 1988 at 1118 hours0.0129 days <br />0.311 hours <br />0.00185 weeks <br />4.25399e-4 months <br />, the NRC Operations Center was notified that a spurious "B" channel ECCS signal had been generated at the Hope Creek Generating Station. No ECCS injection to the reactor vessel occurred. This notification was made pursuant to 10CFR50.72 ( A) (2) (ii) . However, this section

.further states that " ... actuation of an ESF, including the RPS, that resulted from and was part of the preplanned sequence during testing or reactor operation need not be reported." This-ESF actuation occurred while troubleshooting on the "B" channel

! circuitry was in progress. This troubleshooting was being performed using the Hope Creek troubleshooting procedure which requires that the specific plan generated for each proposed job be reviewed with the on-shift STA to determine if the plan could

.cause'an ESF system actuation. During this review, it was determined that an 'ESF actuation- was possible. This

. determination was recorded on the plan signoff sheet prior to the initiation of troubleshooting.

Since the troubleshooting which caused the spurious ECCS signal was'. preplanned and the on-shift staff' was aware of the l possibility, the conditions of 10CFR50.72 ( A) (2) (ii) were met and-no four- hour report was required. Additionally, No LER was required, and none was submitted, since 10CFR50. 7 3 ( A) (2) (iv) contains ~ the same exemption as 10CFR50,72 ( A) (2) (ii) .

l Sincerely, J 8905190350 890505 PDR
