General offices: 1945 West Parnait Road, Jackson, MI 49201 + (517) 788 0550 May 15, 1987 Nuclear Regulatory Commission Document Control Desk WashJngton, DC 20555 DOCKET 50-155 - LICENSE DPR BIG ROCK POINT PLANT -
EQUIPMENT ENVIRONMENTAL QUALIFICATION TEMPERATURE PROFILE Consumers Power Company _ letter dated April 23, 1987 on status of resolution of EEQ inspection findings contained a copy of our EEQ containment temperature qualification envelope as figure 1 in Attachment 3.
During subsequent review of this figure, a drafting error was discovered. Pcints eleven (11)4and twelve (12) are plotted' incorrectly. Pointg1shouldbeat8.6x10 seconds and 115*F and point 12 should be at 2.6 x 10 seconds and 115'F.
Point 11 4
was incorrectly plotted at 9.6 g 10 seconds and 115'F and point 12 was incorrectly plotted at 2.6 x 10 seconds and 115'F. The resultant slight change in slope has no impact on the environmental qualification of our electrical equipment. Attachment I contains a corrected containment tempera-ture qualification envelope. We apologize for any inconveniences this error may have caused.
