In order to meet the requirements of nda measurement, the laboratory of technical research for nuclear safeguards of china institute of atomic energy ( ciae ), is being in charge of developing four sets of nda standards : one set of segmented gamma - ray scanner ( sgs ) uranium standard, one set of sgs plutonhim standard, one set of plutonium isotopic standard, and one set of active well coincidence counter ( awcc ) standard. in this dissertation some pivotal techniques on quality control in developing of nda nuclear standards above were emphatically studied
中國原子能科學研究院核保障技術重點實驗室研製分段y掃描裝置（ sgs ： segmentedgamma - rayscanner ）鈾工作標準樣品、 sgs鈈工作標準樣品、鈈同位素標準樣品和有源中子井型符合計數裝置（ awcc ： activewellcoincidencecounter ）鈾工作標準樣品來滿足核材料nda測量的要求。本論文重點對上述nda核標準樣品研製過程中質量控制的一些關鍵技術進行了研究。 -

We use monte - carlo method to simulate the processes of neutron interrogating uranium by awcc with ^ am - li neutron source for calculating the relationship of neutron coincidence count rate vs. the thickness of uranium foils, the result shows that such standards can satisfy the demands of measurement
我們用蒙特卡羅（ monte rri rlo ）方法，就awcc具體條件模擬計算了鈾標準樣品厚度與中子符合計數率的關系。為了最終計算出中子的符合計數率，模擬計；算分h個步驟進行。
