AIRCRAFT MOVEMENTS AT THE j HARRISBURG INTERNATIONAL AIRPORT JANUARY l THROUGH DECEMBER 31, 1991 f

I

. 1. Total Aircraft Movements - 99,220

2. Total number of movements of aircraft larger than 200,000 pounds is i estimated to be less than 200.

i

NOTE

For Item 2, the data is based on estimates provided by the Capital City Airport Tower (Harrisburg Approach)*. This facility is responsible for tracking Harrisburg International Airport flights.

j The tower is not required to (and does not) record flights by weight j or plane category.

l The total number of movements (200) is less than .20% of the total movements. This compares to the THI-l FSAR assumption of 3%.

• Effective February 23, 1992, Harrisburg Approach is located at the

! Harrisburg Tower.

C311-92-2030 AITACHMENT III Annual Report Regarding the Periodic Leak Reduction Program Tests (T.S. ,

6.9.1.B.3).

Table I summarizes the results of the Leak Reduction Program tests and inspections, by procedure number, that were performed between January 1 and December 31, 1991. Component identification of those components found to be leaking and the type of repair (if required) are included in Table 1. Leaking components were repaired and retested such that the leakage was reduced from the as found condition to an acceptable level.

The two hour site boundary and 30 day low population zone offsite dose considerations were not limiting for acceptable leakage criteria in 1991. The "AS-FOUND" or "AS LEFT" leakage conditions recorded did not significantly increase the magnitude of either onsite or offsite releases during 1991.

{ TABLE 1 (Continued)

The LLRT MAX PATH dAS LEFT" Gaseous Leakage was 17377 SCCH. "As-Found" MAX

.TH was 17737 SCCM - See Note 1.

=he totM "AS-LEFT" Liquid Leakage was 270 ml/hr. As-Found was 330 ml/hr.

The two hour site boundary and 30 dcy low population zone offsite dose considerations were not limiting conditions for acceptable leakage criteria in 1991. All "AS-FOUND" or "AS-LEFT" leakage recorded did not significantly

_ increase the magnitude of either onsite or offsite releases during 1991.

Per TMI-l Tech. Spec. 4.4.1, total leakage less than 104,846 SCCM is considered acceptable for the as-left leakage condition.

NOTE 1: Per t' e " MIN PATH" method of calculating leakage, the As-Found LLP.T Leesige was 87C7 SCCM and the As-Left was 8839 SCCM. The " MAX PATH" method astumes for two valves in series . hat the one with lower leakage has failed to close post accident. " MIN PATH" assumes the opposite.

NOTE 2: lhe valve leak testing occurred on various dates during 1991 9R Refueling Outage. Repairs were performed on the fol7owing components due to higher than desirable leakage:

1. CM-V4: Replaced leaking solenoid.

2. West Fuel Transfer Tube Penetration Pressurization System Joint Leakage Repaired,

3. MU-V2B Yoke Pushing Replaced During MOVATS.

4. WDL-V304 Lapped Seats.

NOTE 3: Considered relatively minor leakage and below the level that repairs would be initiated to repair the leakage.

RESULTS OF SPECIFIC ACTIVITY ANALYSIS -

PRIHARY COOLANT SYSTEM Technical Specification 6.9.1.B.5 requires certain information regarding the results of specific activity ar. lyses in which the primary coolant exceeded limits lof Technical Specification 3.1.4.1 be reported. These limits were not exceeded during 1991. Figure 1 contains a graph of the dose equivalent 1-131 concentration and Figure 2 cont.' ins a graph of the I-131 and I-133 concentrations. The figures show that all values remained below 1 pC1/ml during 1991.

C311-92-?030 A1TACHMENT VI Technical Specification Section 6.17 requires reporting of " Major Changes to Radioactive Waste Treatment Systems." Major changes are interpreted to mean changes that would alter how the system functions or the predicted releases that were previously analyzed.

Based on the above, no major changes were made during 1991.
