Dear Mr. Fitzpatrick:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION REGARDING GPU NUCLEAR CORPORATION'S RESPONSE TO NRC BULLETIN 90-02 " LOSS OF THERMAL MARGIN CAUSED BY CHANNEL BOX BOW" (TAC NO. 76342)
By your letter of May 21, 1990, GPU Nuclear Corporation (GPUN) responded to NRC Bulletin 90-02 " Loss of Thermal Margin Caused By Channel Box Bow." We have reviewed the information provided in your response and have determined that additional information is required in order for the staff to perform an independent review regarding this matter.
Specifically, the information required is as follows:
1.
A complete description of the methodology used in computing the effect on thermal margins including data base, assumptions used and derivation of correlations and equations.
2.
The effect of channel bow not only on the Critical Power Ratio Limits but also on the linear heat generation rate and maximum average planes linear heat generation rate (MAPLHGR) limits.
3.
The effect on the traveling incore probe system (TIP) measurements uncertainty should also be evaluated.
We request that the above information be provided within 30 days of receipt of this letter.
If you have any questions regarding this request, please contact me.
The reporting and/or recordkeeping requirements contained in this letter affect fewer than 10 respondents; therefore, OMB clearance is not required under P.L.97-511.
Sincerely,
/a/
