SUMMARY

ELECTRAK Corporation has received notification about a problem relating to the use of the fire hazards module of the TRAK2000 Cable Management and Appendix R Analyses Software System. The problem was reported by Pennsylvania Power and Light Company (PPL). PPL uses the TRAK2OOO software exclusively for its cable management and fire protection database activities at its Susquehanna Units 1 and 2 site.
The fire hazard module of the TRAK2OOO software tracks and calculates the Btu and minute values of in-situ fire hazards (cable insulation, flammable fire wrap, mechanical items and electrical items) within each of-the plant's fire zones. The calculated values are then compared with the user-defined maximum value for each fire zone. The user is then alerted when the calculated value exceeds the maximum allowed value. The reported error does NOT occur in this portion of the module.

The fire hazard module also tracks long-term and short-term transierit fire hazards as well as miscellaneous in-situ fire hazards.(A-miscellaneous in-situ fire hazard is defined in the software as one that is NOT cable insulation, fire wrap material, mechanical or electrical.) This category of fire hazards requires a combustible type code be assigned to the fire hazard. Combustible type codes reside in a validation table from which the user is able to select an appropriate code for a given fire hazard.

Each combustible type code has a multiplier assigned to it as determined by the PPL fire protection engineer. For example, code XXX is used for gasoline and has a multiplier of l,000,000 Btu per gallon. When a gasoline tank is identified in the database, the user may assign it a quantity value of 1,000 gallons and affiliate it with the appropriate fire zone. TRAK2OOO then calculates the ptoduct of 1,000,000 and 1000 and assigns 1,000,000,000 Btu to the fire zone.

A fire zone may have many in-situ fire hazards whose cumulative calculated Btu values are summed and compared against the fire zone's maximum allowed value. For example, a fire zone has ten in-situ fire hazards of different varieties (i.e., using differentcodes)whose cumulative total=100,000Btu. The user then modifies the multiplier of a particular code to a larger value, which results in Delta of 20,000 Btu. (The total Btu value assigned the fire zone is now 120,000 Btu).

The error occurs when the software incorrectly adds the modified quantity to zero (0)instead of to the previdusly stored cumulative value, thus resulting in a lower and therefore less conservative value. The error is a result of inadequate testing of modified source code that incorporated a requested erhancement by PPL to the fire hazards module. The request is documented as a Software Change Request SCR-0375.
