不定项选择

近几年日本、印度等许多国家积极发展“月球探测计划”,该计划中的科研任务之一是探测月球上氦3的含量。氦3是一种清洁、安全和高效的核发电燃料,可以采用在高温高压下用氘和氦3进行核聚变反应发电。若已知氘核的质量为2.0136u,氦3的质量为3.0150u,氦核的质量为4.00151u,质子质量为1.00783u,中子质量为1.008665u,1u相当于931.5MeV。则下列说法正确的是(   )

A.一个氘和一个氦3的核聚变反应释放的核能约为17.9MeV

B.氘和氦3的核聚变反应方程式:++X,其中X是质子 

C.因为聚变时释放能量,出现质量亏损,所以生成物的总质量数减少

D.目前我国的秦山、大亚湾等核电站广泛使用氦3进行核聚变反应发电
